If 30720 isn't close enough, you might be able to do it with dedicated code in software (bitbang). But you'll need to use some other I/O pins and and a level shifter. Steve was doing something like this with the cassette port. A third way would be to find a UART that is capable of the baud 31250

Hi Brian, I have been looking for one of these to make a basic rom for my PX-8.  Would you be prepared to send one to Australia? If so lease let me know how much you want including shipping. Sure, send me an address and I'll find out what the shipping will be. How about a socket and and 2

CO files only have a fixed location to run from. You're not trying to run it, just transfer it from a saved RAM image. CO files as files in the file system move around as files are created, deleted, change in size. Just like BA files and DO files. Now "trigger files" are a horse of a different

I use RunCpm on Linux. I also just installed in on an Adafruit Grand Central M4 Express microcontroller. Just connect a micro-USB connector and use a terminal program like Putty at 9600. It uses a MicroSD card so I can just copy apps to the SD card. On Sun, Mar 8, 2020 at 13:01 r cs wrote: >

I'm excited about the prospect of CP/M coming to the Model T. Short of rebuilding everything one cares about for 8080, is there an easy way discern which architecture a COM file was built for? Anyone have good luck with any particular CP/M-80 emulator for the 8080 on Linux? Regards, rcs --
