Hi.
I'm searching for a CP/M emulator for the QL.

Anyone could help me?

Thanks!!!

M.

I've got a copy of Success "The Supreme CP/M Code Emulation System" from Digital Precision that could use a good home. I've had it for quite some time, but have never tested it. Just need a mailing address.

So far as I know, there were only two versions of CP/M

Success by Digital Precision
Sandy CP/Mulator

Success was supplied on disk.
The Sandy version came on EPROM with a disk too.

Not sure which is the better version - whilst we have preserved them both, both are still unfortunately, subject to copyright...

Tim - who wrote Success (it will say it on the manual) ?

The manual says that it was written by Brian Watson. Manual was written by Dr. Helmut Aigner and Dr. Andy Aigner.

Hi Tim,

Success was the best CP/M emulator I used on a QL.

The Sandy CP/M emulator needed a ROM to work.

The Sandy Emulator required an Eprom to work, but I had a little bit of SuperBasic to allow a rom image to work.

I think it is just a matter of patching the Eprom address, the EPROM_LOAD command does load the CP/M ROM image and the emulator does run, but for some reason the rom image is unloaded.

I will have to look at some of my older QL systems to find the code.

Please don't mind a question.
Are these CP/M versions emulating a 8080 or z80 processor?
CP/M 2 or 3?
Is there no real CP/M 68K for QL which runs native on our 68K processor?
Kind regards

Paul,

the above CP/M emulators emulate Z80/8080 (Maybe someone else knows the exact CPU) on the QL.

There actiually was an implementation of CP/M 68k available from a company named Quest, sold in a package together with disk drive and controller plus a bit of hardware that allowed bank switching in the lower memory area to put RAM there.

I'm not sure whether that is preserved (I'd guess, not) however and have actually only seen it in advertisements.

I don't know anyone who has seen any Quest products apart from the Adventure program they sold and the memory expansion cards....

Most of their stuff was so ridiculously expensive that I doubt many people bought it...

Hi,

I have an expansion card that plugs into the QL Expansion port and some 5.25" discs, which is 68K CPM.

I never really got it working, need a 5.25" drive.
