Hi.

A really nice package!!

Is there a way to go beyond drive D: ?

Create a drivee.dsk file first.

Specifying a drive E: results in an Bdos Err and Z80 locks up.

I had created a drived.dsk and that is fine.

Thanks

You can attach a two 4Mb drives to I: and J: as well as a 512Mb drive to P:

The main thing to remember when interacting with the images is to
supply the correct diskdef to cpmtools otherwise you'll corrupt the images.

Best wishes

The later versions of the VM has support for 4 4MB drives, I, J, K, L,
but requires BIOS's to support the drives. The tables for supporting the
drives are to large for a 64K CP/M, so there is a 62K CP/M available, that supports all drives. Usually the provided disk space is enough and most
need a 64K CP/M though.

BTW Ken,
on your COHERENT systems login with user udo, no password. In the home dir you'll
find the historical releases of z80pack, when I moved the development from company
UNIX systems to my privat COHERENT systems in 1989. These have no harddisk support
in the VM though, just 4 IBM compatible floppy disk drives, which we were using on
the Mostek Z80 development systems back then.

This is the command I am using to create the 512mb drive:

Ubuntu 20.04 64 bit

cd ~/z80pack/cpmsim/disks

mkfs.cpm -fz80pack-hdb drivep.dsk

This is the results:

You are trying to use CP/M 2, max possible drive size is 8 MB. For the 512 MB drive
you must use CP/M 3 and MP/M, these can handle such a large drive.

Udo,

After spending so much time on getting CPM2 [3] to run where I can make programs I think
I have to reduce my time spent and spend more time on RunCPM from:

https://github.com/MockbaTheBorg/RunCPM

That package works. worked the first time.

Udo I admire your work on Coherent and CP/M but I can't spend endless just getting it to run.

If desired I can provide a simplified install writeup.

BTW, did you ever look over my submissions for bwbasic and focal for Coherent?

No problem, if it works for you then use it. I had a brief look when it became available, works ok,
but doesn't emulate real hardware, so no interesting system programming possible. For me it's
not just running CP/M a bit, I need something like z80pack and that is why it exists.

Of course not, no one can, I also have several fields of interest and must decide what to do,
which is much more than the time I have available for it.

If desired I can provide a simplified install writeup.

Feel free to do this, I'll look at it and include it if it is good.

BTW, did you ever look over my submissions for bwbasic and focal for Coherent?

No sorry, so far I haven't had the time for this, is on my long todo list and sometime
I'll have a look.

Udo,

I have attached two text files.

The RunCPM file is for new installs and updates.

The Applications file shows you basic contents of
the available downloadable ZIP's Disk & User #.
With A[0-9] being the initial included ZIP with the build.

Um how do I attach files?

This is not a Google group. but a copy of usenet comp.os.cpm, so you cannot attach
files like in Google groups. You can attach uuencoded files tho, as usual on usenet.
