Hi Philip,
First of all, WOW! Excellent work! I wasn't aware you had been working
on this silently in the background.
Yes, the remem.bin binary should work with any variant of VT 1.7. The
only real compile differences between platforms is the GUI, and most of
that is hidden by the FLTK libraries.
Funny you mention we need a new hardware solution. Over the past two
weeks, I actually resurrected my old PADS layout tool based NADSBox
design and started porting it over to Allegro. My PADS license has long
since expired but I have an up-to-date Cadence Allegro license. The
thought was to do another run of NADSBoxes. The only real change needed
is to select a new / better SD card socket.
I also have and idea for a project that would replace REX (sorry Steve),
and would allow 64K All-RAM mode in a real M100 without ANY hardware
changes using the OptROM socket only. It would also provide REX
functionality. The only real concern I have is the amount of juice it
would consume from the battery. It would also have integrated WiFi. I
already selected parts and even started an Orcad schematic for it.

Well, it's arrived as far as Virtual T. It will need a new hardware

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
