Thanks Gary
Are you meaning to use CP/M on a real NEC? That would depend on whether
any new hardware developed will apply to the NEC. Once it works on a
real M100, then the BIOS changes required for NEC would be relatively
minor I should think.
I'm curious as to what sort of CP/M programs you found useful on your NEC?

Philip,
It is an amazing thing you have done.
I used to have an 8201A with the PIC-Disk system that provided a full
blown CP/M operating system. After losing that original computer and
disk system to theft, I was left without access to 20 disks of CP/M
files and programs and back-ups of my 8201A memory images for quite a
while. I did end up resolving the situation by the use of some
software called 22Disk, which let me gain access to the disks on an
MS-DOS machine.
But, I still had all these CP/M programs that were unusable to me.
And now, I am wondering, would it be a relatively easy operation to
take your M100 + CP/M solution and port it over to the NEC
PC-8201A/8300 platform? Hoping it may just be a few differences in
BIOS calls and I/O port mappings. This is definitely something I'd
want to try to achieve.
THanks for your work on this!

Rubrik: [M100] CP/M has arrived for the M100
Well, it's arrived as far as Virtual T. It will need a new hardware
device developed to use on a real M100.
Over a decade in the making (started in 2006), I present 64K CP/M 2.2
running in VT with Remem enabled. The Remem is used as RAMdisk, to
emulate two disk drives of about 241KB each.
To share this with the group, it would be easiest to share my VT
remem.bin (6MB). Together with my instructions in pdf, you'll be
on the
air very quickly.
John Hogerhuis: May I send this to you to host on the bitchin.com
<http://bitchin.com> site?
Ken Pettit: Will my windows variant of remem.bin work with all the
other
variants of VT 1.7?
While in theory it will work on a real M100 with Remem, and with
additional software could use a NADSBox to talk to the modern
world (SD
card) - I think as these two items aren't readily available, it would
best if a new hardware solution is developed. Now that it's
working in
the M100 environment, it's relatively straightforward to modify
the BIOS
to work with any RAMdisk, other storage device or even a wireless
solution.
Thanks to Mike Stein for some beta testing.
Philip
