Thanks again!
No question, RAM disks are usually the fastest form of data storage; on the
other hand you can take your FAT-compatible SD card or USB stick over to your
PC where 'transfer' is convenient and also pretty quick...
A REX or even something equivalent to a modified XR4 could probably
Mike here is the latest programming Info doc for remem.
I think the advantage the remem offers is super fast ram disk. Basically
the cpm disk is memory mapped. Other than that remem is way overkill and
complicated...

I suspect he just hadn't noticed the speed button; where is it on the real M100

Actually, when I was testing AsciiPixels a year and a half ago, I
noticed VirtualT was a fair bit faster than a real M100 when it came to
LCD controller access, so I added additional delay to the emulation in
2.4MHz Speed setting. Perhaps It was a little too much delay. If you
run with Max sp
...When are you going to speed up Virtual T?
Not necessarily a bad thing - If it works on the emulator
it may well work on the target hardware :)

Hey Ken,
When are you going to speed up Virtual T? The guy in the video says it's slower
than a real M100 !

Hi Jason,
Welcome to the worl
As I said, I'm not sure what the availability of those uDrives is these days,
but there is Z80 code out there for them and IIRC even CP/M BIOS routines. They
do tie up the serial port though, although you could probably bit-bang SPI or
something similar instead.
There are also parallel<>USB ad
Any of those would solve the 64K RAM issue, even REX2 as it stands I

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 yo
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.

An amazing thing indeed...
However, if all you want/need is to run some CP/M program(s) or work with old
CP/M data disks there are quite a few CP/M emulators out there for pretty well
any platform, as well as programs to convert among different disk formats.

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 8201
