The Sinclair QL Forum

Is there a way to get 68k/os working on a real ql ?

without the special eprom card ? , or has someone re-created that card .

It works in the emulator - so probably just a case of 'cutting the ROMS' so that you can run it from there - there is also a supporting Microdrive image required - so you'll have to create that too.

I have the 68K/OS image on one of Tetroids ROM switchers - and it certainly boots into the OS - but I don't have the mdv image with the extra bits on - so I know it boots at least.

Have a look here https://dilwyn.qlforum.co.uk/gst68kos/index.html

I think the files are there, but not as an MDV image. If you can figure that part, you might be halfway there.

the rom does work , now to learn how to use it

is the asm also available as rom ?

are there any other roms available ?

is there someone who has recreated the pcb ?

How should one create an mdv dump which is also recognized by this OS? As far as I know, GST uses a totally different way to read and write the mdv.

is there a copy of the pcb developed by someone ??

as i see the os is in rom on the pcb .

For those who ever wanted an original GST Sinclair QL EPROM expansion card with their 68K/OS Z570V218 and the associated Microdrive Cartridges 68K/OS and 68K/ASM, there's currently a set on ebay (ending 2024-04-24):

BTW: This auction also includes HiSoft DevpacQL and CP/MULATOR. I'm not the seller nor related to him.

It would be great if someone of the QL community would take good care of it and - after refelting the Microdrive Cartridges - make backup copies of those Microdrive Cartridges. Maybe one day, someone adds 68K/OS Microdrive support/emulation in a Q-Emulator or even on hardware Microdrive substitutes.
