Description
Since I didn't see any info for this anywhere online, I figured I would share my findings!The X68000 PRO internal SASI connection will work with a standard HD50 50-pin SCSI cable to a SASI/SCSI device, which is a lot more convenient than having to build a cable or find a 20-pin SASI cable, which is used in all other units.
For beginners of the X68000 who want a solid, easy-to-use unit, I would definitely recommend starting with the X68000 PRO or PRO II models.
Granted, the other units all look way cooler, but natively they only have two expansion bays (PRO has four) and they require a proprietary SASI/SCSI cable, which can be challenging to find and/or build oneself.
On the back of this unit, I have wired it up with an AztecMonster Compact Flash to SCSI adapter, with a 2GB CF card running Human68k 3.02.
Nicer setups will most likely have the drive inside, but this is necessary to make imaging and swapping CF cards much easier for the time being.

Certainly!
I will check my notes (PMs) and will get back to you shortly.
Good luck with your X68000 unit, hope you have lots of fun with it!

Oh mate! Thanks a lot....I'm waiting for you since I have found the same board you installed here www.artmix.com/CF_AztecMonster… and it seems great but as a Noob for the Sharp "world" I'll be waiting for your precious tips and help on how to install it....
Many many thanks actually

I got your note, but I will just respond on here in case anyone else comes across this question.
Yes, make sure to use a standard 50-pin flat-ribbon SCSI cable with the Pro models.
The cable should be like this: www.amazon.com/Connector-50-pi…
You won't need a passive or active terminator for this, either, as the AztecMonster has built-in termination, which is a nice feature.
Even though the Pro models have SASI controllers (basically SCSI v0.5), the SCSI-based AztecMonster is backwards compatible with it, and should be detected at POST automatically.
I did notice that the 50-pin flat-ribbon SCSI cable is keyed at the top-center of the connectors, but it will still fit into the Pro models; it might break the edge of the SASI connector on the board, but it is just plastic and won't affect the connection at all.
If you don't want to break it, you can just grind off the keyed part of the cable, and it will slide right into place on the Pro motherboard, or optionally get a non-keyed 50-pin SCSI cable.
If you are just planning on running Human68k on the AztecMonster, any flash-based CF card will work.
But if you are planning on running NetBSD on the AztecMonster, I would recommend getting a CF-based 6GB 3600RPM MicroDrive.
The only reason I recommend this with NetBSD, is that data corruption can occur on flash-based media when using NetBSD on the X68000 units, and I believe it is due to a timing issue with the reads/writes on the flash-based disk; these errors and data corruption do not occur at all on the MicroDrives, though.
Again, if you are just running Human68k, any flash-based CF card will work perfectly; I have had the best luck with sizes between 2GB to 8GB, but the size you choose is entirely up to you.
Good luck!

HI,
actually thanks for sharing your experience and I got it all!!! Just to know and have your precious opinion, a mate from Sharp groups reported me this link www.itead.cc/scsi2sd.html what do you think about this SD-Card solution?....Now that I have your confirmation an ordinary 50-pin Scsi cable will work, it is really great!!!!...I immediately look for one and then once you reply to me to choose up the better Card solution btw the Aztec and this last one, I'll proceed with the order....
Cheers

While I have not personally used the SCSI SD card adapters, I have heard they work with mostly good results, depending on the model.
The SCSI2SD model that you posted does work most of the time to my knowledge.
If I were in your shoes, I would absolutely go with the AztecMonster, if it is available, especially since it supports SASI and SCSI out of the box, and it works 100% with all Sharp X68000 units, along with Human68k and NetBSD, but it is totally up to you.
AztecMonster units are becoming very rare, and hard to obtain if they are new, since I don't believe they are made any more, and if you have one available, I would get it anyways since they work great for other legacy/retro computer equipment as well!
👍: 0 ⏩: 1
That's perfect! I know mate, my first choice was the AztecMonster but I had a look at the price and this one would cost around 130/140$ shipped and the
SCSI2SD 3.5" 50-pin SCSI to SD Card Adaptor would cost around 80$ shipped....moreover I read that there is this SCSI2 50pin to SCSI1 DB25 Converter Adapter ( here is the link) www.itead.cc/scsi2-50pin-to-sc… and so maybe use it as external but I do not actually know if it works this way. Yet, both solutions seem great, what do you think now in the end with the last information I have just given? I swear this is the very last time I bother you on this topic.....until the arrival of the Card and maybe I'll need some help....( hope not so not to tease you anymore....)...ehehehe!!!!
You are very kind to me sharing your time, I appreciate it!
Cheers

Nah, if you want an external solution, stick with 50-pins and use these two cables:
6ft 50 pin Half Pitch D Subminiature HPDB50 to Centronics CN50 Male M SCSI Cable
www.ebay.com/itm/6ft-50-pin-Ha…
57" SCSI 50-Pin IDC50 2-Drive Cable w/ External HPDB50 Female Connector
www.ebay.com/itm/57-SCSI-50-Pi…
If anything other than the AztecMonster or SCSI2SD solution is used externally, then an active SCSI terminator will be needed.
Oh definitely, I hope you get everything to work and will have some fun on that system of yours! ^_^
👍: 0 ⏩: 2
....but if I used the external solution, Would I be able to use both aztecmonster and SCSI2SD or I need a HD?
sorry again...I'm about to decide and order everything but as you may see I want to be really certain on what to do...
Cheers

So, it seems that the best solution is going with one of the two cards AztecMonster or SCSI2SD and directly connect it internally so not to have any issues, right?
In this case to me it would be enough to get a 50pin SCSI cable and go for the goal.....maybe trying with an external connection will get me onto trouble and config might not appear to be simple and easy to go.....sorry mate as I told you I am quite a noobfor whom it may concern the Sharp world....but your opinions and suggestions are leading me on the right path...
👍: 0 ⏩: 1
Yes, either the AztecMonster or SCSI2SD should work; 100% on the AztecMonster across the board for sure.
It really doesn't matter if you setup the adapter internally or externally, as both will function the exact same, so the only real difference is that internally it would require only the one cable, while externally it would require two separate cables.
I ended up setting up mine internally, though it is physically sitting on the outside (see pics above) since there wasn't a good spot in the case due to the other expansion cards and Xellent30PRO CPU accelerator being used.
But again, other than the cabling, the software setup and configuration, as well as performance, will be identical, as both internal and external SASI ports use the same chipset and bus.
Hope this helps!

last sentences then I'll stop putting you off....As I'm currentrly living in Milan, Italy I have just found these ones for a possibile external connection to my Sharp....this one is the SCSI cable tel me if it is ok....and below I added a link on an adapter ...what about??....
www.amazon.it/gp/product/B00A2…
www.amazon.it/Centronics-Gende…
👍: 0 ⏩: 0
ok I see.!! so both are valid....just tell me one thing, why does the external solution, still with one of the two cards, need two separate cables?....
👍: 0 ⏩: 1
The first link you posted will work, but the M-to-M gender adapter plug in the second really isn't needed.
I've never been able to find a "Centronics CN50 to IDC50" cable, which is why the two cables I posted were necessary.
If you can find one of those cables that does all of that, though, then go for it!
Externally, it would connect in this order:
X68000 -> (cable 1) Half Pitch D Subminiature HPDB50 to Centronics CN50 -> (cable 2) IDC50 2-Drive Cable w/ External HPDB50 -> AztecMonster/SCSI2SD
Internally, it would connect in this order:
X68000 -> HPDB50 to HPDB50 cable -> AztecMonster/SCSI2SD
Both will have identical performance and the exact same software configuration and setup, and both will have the same behavior overall.
I had to setup my X68000 Extpert-HD unit with the external solution since I needed to boot NetBSD off of the SCSI card instead of the internal SASI controller, and you can see the two cables in use here:

Hi...I got my Sharp and I have to unbox it but first I want to make some games myself, I have a 5.1/4 floppy drive and some HD floppies to use....can you help me out?
I know there some programs but the one I'm using, Omniflop, is hard to configure and even if my OS that is Win 7 - 32 bit recognizes it I'm not able to create my copies.....could you give me some tips/procedure and/or aother programs which allow me to perform this easy apparently operation?
Thanks in advance as I always....
Ps: I ordered the SCSI2SD with cables and once I get it I'll that one.....
👍: 0 ⏩: 1
Ah yes, OmniFlop is what I used as well to create the 5.25" diskettes for the X68000, either blank or from images.
I never had any luck with it within Windows 7, not to say that it won't work with that OS or anything, but I had the best luck with Windows XP.
The computer I used with it was an older Pentium 4 model, circa 2003, with support for 360KB/720KB/1.2MB 5.25" floppy diskette drives in the hardware (BIOS).
It is important that the computer you use with OmniFlop has hardware support for 5.25" floppy diskette drives, otherwise the software will think that it is a 3.5" diskette drive, and won't function properly with the OmniFlop software.
Also, when formatting, make sure to use the X68000 formatting options within OmniFlop.
They can be tough to find, but they are definitely in the list, despite the list being huge!
Nice, hopefully the SCSI2SD arrives soon.
👍: 0 ⏩: 2
in the meanwhile I'm asking you if there is a particular procedure to perform once I get the SCSI2SD and plugged into the Sharp to allow this one boot from the SCSI2SD though and so make it recognize the image in the Sd Card full of games and already prepared as I found on various Sharp forum sites....
tks again!!!
👍: 0 ⏩: 1
Sounds good, and yeah, your Windows 98 system (depending on the year it was manufactured) should hopefully support 5.25" diskette drives in the BIOS.
Nope! In fact, if you have the SD card already imaged, you should be able to boot right into the SCSI2SD.
If the unit doesn't boot to it right away, a change may have to be made in the X68000's firmware (battery-backed 16KB SRAM); also make sure your battery is good.
The firmware can be modified by booting into a Human68k diskette and running the SWITCH.X utility, and then modifying what disk drive the system boots from the HDD (STD = FDD).
You can also adjust how much memory your system physically has access to, along with quite a few other settings.
All you really need for this is the keyboard, as the mouse is not necessary for any of these functions.
More information on the firmware can be found here: www.gamesx.com/wiki/doku.php?i…
More information on the SWITCH.X utility can be found here: www.gamesx.com/wiki/doku.php?i…
If any changes need to be made to config.sys, you can do so by typing the following: ed.x config.sys
This will edit the first startup configuration script the OS reads upon booting, similar to how MS-DOS reads its own config.sys or AUTOEXEC.BAT files.
Hope this helps!

Hi there,
just a question on the spot as I' m trying to write some floppies for my Sharp x68000.....which format/floppy do I have to use in order to finally accomplish my mission and def play them all on my Sharp?...I have plugged my 5.25 floppy drive and it seems that my old pc sees it correctly but when I come to the end of Omniflop procedure it says that media is not ready and to check again.....I'm on my Win xp and the hardware is seen by the system but now my doubt is referred to the media I own....I was told they are HD 1.2mb disk....
If I cannot accomplish this mission I actually want to achieve I'll wait for my SCSI2SD patiently.....but I'd like to write my own floppy ..damn it!!!!
Thanks for your usual prompt aand kind opinion
👍: 0 ⏩: 1
Make sure that rectangular hole is cut on the side of the 5.25" floppy diskette to put it in write-mode, otherwise the diskette will be read-only.
Also, make sure the diskette is an actual 1.2MB 5.25" diskette, and not a 720KB or 360KB diskette; not all of them are created equal.
You want to use the X68000 format within OmniFlop for 1.2MB 5.25" diskettes: gamesx.com/wiki/doku.php?id=x6…
"78/2/8x 1024 Sharp X68000 78-Track 1248Kb" & "77/2/8x 1024 Sharp X68000 77-Track 1232Kb" should be the two available options, and either should work.
Also, choosing the "Format-Write" option is also recommended since it will format the disk before writing the image contents to it.
Again, make sure the diskette drive hardware in the BIOS is set to 5.25" 1.2MB, otherwise the OS may identify the drive type/capacity incorrectly.
Hope this helps a bit!

Hi there,
hope everything is ok!! At last I got it!!!! Tested my Sharp X68000 Pro II with floppies formatted and the written through Ominflop on Win XP and here we go everything turned out for the best!!! I took me time to test here and there, finding an old Monitor I luckily stored in my cellar time ago, use a female-to-female vga connector and thanks to your suggestions/tips too I got it worked!!!!! Now the last challenge would be to plug my SCSI just arrived from HK and plug it externally to finally accomplish my best retrogamer achievement....ehehe I can say that there is much more satisfaction inserting my own floppy game and this way makes me feel like a child before his Xmas gift.....I'll keep you posted to give my last report on that.....
Cheers

Oh man, that is so awesome, great job getting everything to work!
I'm really glad that it is all working well and that you can enjoy the system to it's full extent, at long last.
Yes, merry Christmas to you, haha, the X68000 is definitely the gift that will keep on giving.
Nice work on that monitor connection, too, sometimes those can be a bit tricky with the adapters.
Hope to hear more from you, and if you have a chance, upload a pic or two of your setup, I would really like to see it! ^_^

Hi mate, are you fine?
I have been enjoying my sharp x68k and in short I'll be sending you some pics ( if possible here..)...I have almost received all the components to plug the scsi2sd, cable, adapter and now I was wondering if I needed a micro sd card of only 1 gb or I may use a 2/4/8 gb one, might you answer this question?..I do not know if a card size more than 1 gb ( or 2 though) is supported by the Sharp system and last but not least question, in you opinion does the external scsi port supply power for the scsi2sd ( I read there's a chance but not sure about) and if not, how can I power it?
Internally I know there a molex cable ( hope it is 5v otherwise I risk to grill it with 12v) but externally I have some serious doubts....maybe you are able to clear them all...
many thanks
Max
👍: 0 ⏩: 1
I believe the file system which Human68k can utilize up to 4GB on a single partition, but any size SD card can be used; the additional space will just go unused with the original partition.
The largest SD card I have used is a 2GB with Human68k, and a 6GB MicroDrive with NetBSD on the X68000 units, but I'm sure any would work.
Unfortunately, the external SASI port on the earlier X68000 units, or SCSI port on the X68030, does not provide power, and only provides data.
The molex connectors inside use ATX-standard 12v/5v power, and I believe each molex cable is capable of 25 watts of power (total), though the SCSI2SD drive probably only uses a few watts at most.
I am using the internal molex cable to power mine, but finding external molex power supplies are pretty cheap and easy to find, like this one:
www.amazon.com/AGPtek-Drive-Ad…
It is also possible to just feed the molex cable through to the outside of the case, or even use a molex extension cable so you don't have to stretch the internal cabling, but either will work.
Hope this helps and that you are doing well!
👍: 0 ⏩: 1
ok I'll do as you explain me here....using the internal molex or an adapter btw just a tiny doubt about this internal molex, if I plug it directly to power my scsi2sd would it give the right 5v power or as you said it gives both 5/12v I have to modify it?...I do not want to risk and grill my card.....
tks for yr constant hepl...
👍: 0 ⏩: 1
All AT and ATX-based molex and berg connectors are normally 12v and 5v, I've never seen any that are just 12v or just 5v, unless of course they are missing two of the cables, such as what are on some computer fans.
You won't fry the board with it, unless of course you plug it in upside-down, but that's kind of hard to do.
I do surprisingly have one power supply that was from an external 8" FDD drive carrier which uses 24v and 5v, but these were normally only found in the 1970s and early 1980s, and are extremely rare.
If you are truly concerned that your SCSI2SD drive might not work on the molex plug you've got, just plug in any other drive, especially an optical (CD/DVD) drive into it and make sure it works, and then you should be good.
The reason I'm recommending testing with an optical drive is because all 5.25" optical drives utilize both 12v and 5v rails (12v for the motors, 5v for the electronics), and are cheap and easy to test with.
Or any molex-powered HDD will work, too, as they all use the 12v and 5v rails as well (SCSI and PATA only, though).
One last thing, take a look at the very top photo above, and you can see that the internal molex plug is being used on my AztecMonster with both the 12v (red) and 5v (yellow) rails.

ok, that's good and very clear explanation! Now that I have found a 2gb micro SD card and all the cables I may try and plug my Scsi2sd so during these we days I'll be able to open the Sharp and check everything, molex and stuff.....anyway if I have a doubt or sth might seem to me too weird, I'll be back to you...

I haven't got round to opening my Sharp yet these days are busy approaching Xmas, anyway I have just uploaded the pic of the power connector the guy who sold me the Sharp x68k sent me once....have a look at it and tell me what you think about, now if its voltage was correctly 5v I'd need finding a 3-to4 molex adapter in order to plug my SCSI2SD without grilling it....is that right?
cheers
👍: 0 ⏩: 1
Interesting, I've seen some of the older X68000 vanilla and ACE units use that, but by the Expert and PRO era of models, those were mostly done away with.
Yes, that cable is both 12v and 5v, with a single ground in the middle for both, if I'm not mistaken.
Once you have a chance, please open your X68000 PRO case up and take a look, there should be at least one standard 4-pin molex cable in there, especially since it is the PRO model.
I could be wrong, but I would take a look to double check.
If not, I can dig around and find the page for what needs to be done to convert that 3-pin adapter.
Let me know if you have a chance!
👍: 0 ⏩: 2
I lost my msg and do not know if I sent it to you thoroughly so one thing (sorry if repeated) .. just in case my Sharp has the 4-pin molex cable will I be able to plug into my SCSI2SD being sure to power it properlly through 5v?...I mean if the cable has both 12v and 5v does the card get directly what it needs or I risk to grill it if it gets 12v?.....I swear this is the very last question on this topic....ehehehe!!!!!!
cheers
👍: 0 ⏩: 1
Yep, the molex cable will be both 12v and 5v, of which the SCSI2SD card uses both of, so you should be good.
Hope you have a merry Christmas as well! ^_^
👍: 0 ⏩: 1
I asked you that because even in the Technical Specs here www.itead.cc/scsi2sd.html it is reported the SCSI2SD card uses only 5v that's why I wondered if connecting the molex which also has the 12v would not damage it.....that's all
👍: 0 ⏩: 1
Ah, you are right, the specs do indeed say it is 5v only.
However, the molex plug on the unit have for pins, so it just won't utilize the 12v, even though it is plugging into it.
This is much like how modern solid state drives using a SATA power connector will only use 5v (very rarely 12v), even though there are 5v, 12v, and 3.3v rails going into it.
Hope this helps, and thanks for that link!
👍: 0 ⏩: 1
yes, you mean that I' ll be able to plug the 3-pin power into the 4-pin of the SCSI2SD card and that's it!! If so it is good to know!!!!
Many many thanks mate, I wih you all the best and once I come back from the mountains on 30th those days I'll be off and ready for every try on my Sharp.....anyway it is a very good and "fascinating" old Computer....Japanese did right in the past, here in Europe we have always had Amiga that it another giant and "charming" World.....
👍: 0 ⏩: 1
Well, I'm not sure about the 3-pin power adapter itself, but if it is indeed there, and a 4-pin molex power adapter isn't found, I do know there are ways to convert them so they will work.
But we can take a closer look once you get back to make absolutely certain that it will work.
The Sharp X68000 really is a great workstation with so many cool features, and I can't wait for you to start fully enjoying yours.
Hope you have lots of fun up in the mountains!

Hey mate I read somewhere that I could connect my scsi2sd card to a micro usb mob phone power cable that is actually 5v cool isn't it?..so I can skip the power issue if my Sharp, as I think, will not power directly it from scsi external connector.....now I'd need a walkthrough guide to start installing it....I found the way to format the 2gb micro sd card with winImage and now it is ready to go....I'd need a guide to be followed step by step not to make mistakes!!!!

Nice work on prepping the SD card!
Huh, I looked and didn't see the pictures you posted?
That's ok, if you use one of these power adapters, it will work with your SCSI2SD:
www.amazon.com/AGPtek-Drive-Ad…
If you can post those pics of the cables you have, maybe we can take a look to see what kind they are, and if there are ways around them, but if you are going to keep the SCSI2SD external anyways, I would just use the power adapter in the link above to power it safely.

I have just clicked on submit above and you should see now the pic of the connectors anyway that is not important since I decided to plug it externally and I'll power it through a usb mob charger that is really 5v output so bingo!!...now I have plugged my card, done with the image on the micro sd and ready to go but.....what here comes the hard way, which guide/what do I have to do from now on with my Sharp pro II model 653 to accomplish my way to Heaven....? I'd need a step by step guide to do everything correctly. reading here and there on line I found sth but nothing precise and as I do not want to commit any mistakes I should follow a sage way above all because the language of Sharp computers is Japanese and once I do sth wrong I won't be able to figure it out !!!...Any ideas?...

Um, wow, that is a very modern power supply in that X68000 - 12v CPU connector (early 2000s), SATA power, and two FDD Berg connectors, not to mention the 20/24-pin ATX power connector.
That must be a modded X68000 Pro unit, but if it powers on, that's pretty darn cool!

Hi mate, I'm back 'cause a strange thing has just happened to me, as you may see from the pic I uploaded I got a message from boot screen but I cannot figure out why that....
yesterday I set everything as I wrote to you here connecting my scsi2sd and set parameters and carried out commands correctly as written here below....the only thing I did after my installation yesterday was to unplug my scsi2sd and put in a safe box but obvioulsy I did it after switching the system off.....incredibly weird!!!...I tried to connect the scsi2sd to my pc to see if everything was ok and I noticed that I had to re-set the parameters but even if I clicked on save and reload after theoperation it seems that the card does not store ( saving) the parameters set out....apparently it said "successfully saved and loaded"......hope you can help me out....maybe do I have to re-install the master floppy again and make the operation again to set sasi etc....?...
use scsi2sd-util.exe
- connect the SCSI2SD device via a microUSB cable to your computer and launch scsi2sd-util.exe
- from the File menu select "Upgrade Firmware..."
- select the above firmware file and let it update
- click on "Load from device" button
- On "General settings" tab:
Startup delay = 0
SCSI selection Delay = 255
all options should be disabled
- On Device 1 tab:
Device is enabled
SCSI ID = 3
Device Type = Hard Drive
SD card start sector = 0
sector size = 512
sector count = 2048000
- click "Save to device" button
- click "Load from device" button to verify the settings have been stored

If the battery is bad in the X68000, that will reset the SRAM parameters (what tells the X68000 to boot from which disk).
If the setting is still set to boot from the HDD (SCSI2SD), then it might just need to be reseated with the cable.
I've had the AztecMonster from time to time not show up in that boot list in the picture you posted, and will wiggle the cable, reboot, and every few times doing this, it will finally show up and will boot properly.
This is nearly 30 year old equipment at this point, and booting a SCSI device from SASI can from time to time present strange boot issues like this, but with a few reboots, wiggling the cable (sounds weird, but it works), and making sure the SRAM battery is good, it should finally boot into Human68k just like you were doing before.
I believe you are definitely doing everything correctly, just do your best to have patience and learn the behavior of your X68000 unit, as each unit individually seems to have a different operational behavior that it unique into and of itself.
My X68000 Expert-HD never has the boot issue that my X68000 Pro has, but at the same time, the Expert-HD has other quirks that the Pro does not have, so go figure.

I tried several times to wiggle the cable and plug and unplug it but it seems to be a sram issue as reported in a screen just uploaded here similar to mine i got on my Sharp so I think that I may need to replace the battery....could you tell me the right operations to perform and , hoping it'll be easy to find once I open the case, which battery I should buy to correct replace my od one?
I remember you that my model is the CZ653C so the Pro II.....so I accept suggestions for the right purchase ( type and model of the new battery) then once replaced if i need to perform any other operations or it will be enough to repeat the sram procedures in order to get it fixed and stored into the Sharp sram.....
many many thanks mate
