Hi Roger
Well there's really only the serial & printer ports remaining. All other
I/O is done. I thought I'd wait until any hardware is developed to do
those. I've fully implemented interrupts, while CP/M doesn't use them -
we can, & make use of the system ROM routines for I/O. After Import &
Export utilities, I'm pretty keen to get it working on my real M100 with
Remem.
This is all my code, I started afresh from the mtcpm effort. However I
will release it after any hardware is developed & it is a fully working
system.

Phil,
I was thinking more of the bios calls. The drivers for hardware.
Also, will the source code be released?

Hi Roger
I did those as part of the installation. Starting off with the
assembly listing of CP/M 2.2, I was able to build it up one step at a
time. That's different than the traditional Regeneration process of
pulling the binary down from a floppy disk.

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 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
