WANTED: Patch for Risc PC support of Acorn's software PC Emulator (!PCEm)

Post by flibble »

In theory there's a patch around that makes Acorn's software PC emulator (!PCEm) work on the Risc PC rather than just the 3.10 era machines.

Does anyone have this patch?

As a backup, does anyone have a patched copy of the program?

I've got several copies of this (all appear to be identical) beneath Utilities in my RISC PC 600 hard drive.

This is a zip made with Spark FS on the RPC 700, so it should preserve file types etc.

Interesting, what version of Windows runs under PCem? Does 3.1 run, or something even earlier?

PCEmu is an old 'real-mode' 8088/8086 emulator so the latest Windows that runs is 3.0, 3.1 dropped support for it. I've read a compatability note that suggested Windows 2 and 1 also worked.

I paired Windows 3.0 with DOS 5 instead of the 3.30 that normally shipped with PCEm, this let me get around the 32MB HD partition limit that was in 3.30.

I also installed the DOS version of BBC BASIC from Richard Russell's site, it's working well.

But I've yet to figure out the mouse driver ... this makes using Windows a bit of an arse.

ISTR that no mouse driver was needed for Windows 3.0, since it was "hardcoded" to support a Microsoft bus mouse, which was emulated by PCEm.

For DOS of course, you needed the Microsoft mouse driver, which was supplied with PCEm, but the standard DOS (delivered with MS-DOS 5.0 and PC-DOS 6.3) mouse driver worked fine, once you figured out that autoexec.bat/config.sys stuff. Very IIRC.

Have fun

Ta for the pointer (no pun intended), the mouse was already working. I just hadn't realised that mouse didn't work unless PCEm was in non-windowed 'single tasking' mode.

When I ran PCEm to see what versions I had, it went into single task mode and I couldn't get out of it without pressing the reset button, which was annoying as the RPC was doing other things at the time. Is there a less destructive way to exit?

I had to read the manual ... down with this sort of thing.

Press the middle mouse button to leave single tasking.

Manuals here,

Does Alt-Break also exit PCem single tasking, or is that just for the podule PC card?

Great, I will try this when the RISC PC isn't doing something else. Currently it's been running VKiller for the last 22 hours, and still only about 60% finished!

Killer's surprisingly slow... you might find Kiwisoft's Slayer a bit quicker, if you can find a copy. It was released as open-source some years ago.
