PIO-6834-1M is an internal 1MB memory expansion board manufactured and sold from 1989 by I.O Data.

Super you can just use Amiga 4000 coin cell battery adaptor

Excellent that memory upgrade is 1mb so your base memory will be 2mb, very important.

Use X68000 drives directly? As in connect them to PC to write disks.
Yeah that should work. Would need to rig some extra signals if you want to Eject the disk or just plug it back into the X68000 to do that.

Ah yes @alexh found the PCB info. alexh I do have a X68000 to trade, but there is probably only 2 computers left I want - Amiga 3000 and Sam Coupe.

Once the harddrive (sd / cf card whatever) is set up and you can boot into an environment like LHES then there’s a handy programme for writing XDF disk images onto floppy from the X68000 itself. It’s useful for those games which are a pain to install onto the hdd.

So a few bits of wiring later and ...


I have an inline floppy adaptor thing and several goteks. But so far no luck in this department.

Super. Now your into the realm of configuring the SRAM.

You will need to boot the 'Masterdisk V2'. And load Switch.c to configure.

Gotek, I guess they are flashed with Flash floppy. So can use X68000 images converted to .hfe

I am struggling to remember and currently watching a film with the misses so will look into it tomorrow ;) but your not far off now.
If it boots a disk that is not the right one, you might see a message with 'Human.sys' least you then know it is reading disks.

Update: Film finished, having a look now and my Goteks have S0 and S1 jumpers fitted. No MO or JC.
I can Attach my Masterdisk disk image tomorrow. Sharp released everything public domain so should be no issues attaching :)

I'll need to jury rig a keyboard later too. MIght need help from @arkadiusz.makarenko

One of those USB adapters I mentioned are really good, cheap and quite simple to make. Run Keyboard and Mouse off the same port. Need a ProMicro, USBHost and Level Shifter.

Probably some PIC code about for the PS/2 keyboard adaptors floating about, that probably has less parts as a temp measure to get you by.

Stay up late watching a film and then my daughter wakes up at 4:30am. Feeling brain dead.

Anyway this contains the Masterdisks, just need V2 and it has the SASI bootloader. Plus some other things. I think V3 just has a newer Switch.C My Gotek does not have any config files on the USB stick, just the .hfe's

If you get disks booting then lots of games just need a joystick to work (MSX compatible), Salamander is a good one.
With 2mb memory lots of games work. It's mainly when trying to run off HD that you need more memory.

Hmmm... This one?


Porting this to full USB shouldn't be too difficult.

Testing and debugging might be more challenging.

Right so i cycled through the disks and they do get read. Only memtest actually works. The first three disks give


Memtest seems to work...


And the other 2 disks (unsure of what they are as its just gotek numbers)
