Gary What I can do is send you the BIOS source & you could look at adapting that for NEC. In theory with Woolly taking care of the disk side of CP/M, only the keyboard/screen I/O, RS-232 & printer I/O will need adapting for all the different models. As Woolly gets developed for the various

[M100] CP/M Expander

Great Ken. Changing thread to "CP/M Expander" Is it really possible to fit all that on OptROM form factor? Would it need a heap of wires soldered to motherboard? Philip On 12/07/2017 7:14 AM, Ken Pettit wrote: Downloaded the remem.bin file and ran CP/M under VT 1.7 on Linux. Works great!

Re: [M100] Alternative he for cpm

Any of those would solve the 64K RAM issue, even REX2 as it stands I believe. What about RAMdisk/Disk & transferring to the outside world? Mike Stein pointed me to some micro SD adaptions out there, such as this: https://www.4dsystems.com.au/product/uVGA_III/ Could an OptROM sized board

Thanks for the congrats, guys. Once I've got some decent Import/Export routines done, I'll make up some disk images featuring languages, adventures (Zork for example), games (if there are many out there). These could be also be hosted on Bitchin100.com as separate remem.bin files, so to be

Re: [M100] CP/M has arrived for the M100

if I understand . Lower 32k space has either m100 Rom or ram. . Upper 32k space has a single ram block. I guess you access the disks using the fine grained ram access? 1kb at a time? On Saturday, July 8, 2017, Philip Avery <pav...@xtra.co.nz <mailto:pav...@xtra.co.nz>> wrote:

Re: [M100] CP/M has arrived for the M100

bank switching to std Rom? In terms of hardware... not easy to map to rex. Rex2 maybe. But one could imagine a hybrid that uses the rex technique for writing to a read only socket to enable at least 3 banks of ram. On Saturday, July 8, 2017, Philip Avery <pav...@xtra.co.nz <mail

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.
