If it doesn't, we need a clever developer who is very intimate with the Model 100/200 architecture and the 8085 to port it :) Someone in the Color Computer community ported CP/M to run under OS-9 on the 6809. If that can be done, it seems that getting it to run on an 8085 would be plausible.

Are you sure it's not CPM for the TRS-80 model 1? I had a copy of that but it required a switch on the model 1 that swapped out the ROM with a block of memory by fiddling with the address lines. This gave CPM the contiguous block of RAM starting at address that it needed to run. I had

Ah, CP/M ! It's something like the Loch Ness Monster of the Model T-community. A lot of people believe it exists, Few have ever seen it, But until the scientists of Jurassic Park come along It continues to elude us. Greetings from the TyRannoSaurus Jan-80 @ work( - @ )

He's basically built an emulator/VM that runs in OS-9. There was a lengthy discussion about the finer details on the CoCo list, but here is one of his videos demonstrating it running WordStar (wow flashback!): https://www.youtube.com/watch?v=Ysn7Na60ZGA Date: Mon, 1 Jun 2015 08:50:14 -0700

A cousin of these devices, the NEC PC-8500 is a pseudo-CP/M computer. It has WordStar-To-Go built-in and it can be made into a full-fledged CP/M computer by adding the 32KB memory expansion cartridge and the floppy disk drive/drive interface. Just an FYI. On Mon, Jun 1, 2015 at 9:17 AM, Joe

The CP/M machine that I used as an RPFT was 8085 based. I have seen more versions for the 8085 than for the 8080. Frederick Whitaker Sent from my iPhone On Jun 1, 2015, at 11:50 AM, John R. Hogerhuis jho...@pobox.com wrote: On Monday, June 1, 2015, Joe Grubbs jsgru...@hotmail.com wrote:

Too slow for Wordstar cp/m? Back in the day, I used an Epson PX-8 with dual disk drives and a 128K RAM pack -- all of which I still have. It ran a ROM based Wordstar. If you had a 4 page document and you made a small change in the middle of it, you could hit return then go fix lunch, eat it at

[M100] Accelerators

I was just watching a review video of the old Apple IIGS, where he talked about getting a processor accelerator. I Remember the accelerators for the Amiga, even one for the C64. I wish there were a turbo board one could drop in on an M100, replacing the 80c85 with an 8088 (or low-power
