I've been having a play with the MESS Super-80 emulation. It all seems to run quite well - many thanks Robbert and the others responsible for emulating this machine. I copied my BASIC tape to a wave file and it played straight in - not bad for a 28 year old audio cassette. I also have BASIC in ROM, but the BASIC tape was the only obviously 300 baud oneI had. Most of my tapes were made using a heavily modded 2400 baud tape interface. My machine was modified to run with a floppy drive using an interface made by MCE. Does anyone know how hard it would be for me to write some sort of floppy drive emulation? I converted most disks to images on my PC a few years ago, so I've already crossed that bridge. I have no desire to run CP/M, since I migrated all my Super-80 CP/M software to a CP/M emulator many years ago. I'm interested in running "Super-80 DOS", which was a very primitive track-based operating system. Hopefully, the primitive nature of S80 DOS would make it easier to emulate!
