I have about 6, a few with the 64k multiunit for the RAM driver. I have a dual-serial Rpi that provides 4 floppies using Vfloppy and a serial console on the other port. I need to start selling some! On Wed, Mar 11, 2020 at 14:51 Tom Wilson wrote: > Also, if you're looking for an 8-bit CP/M

Also, if you're looking for an 8-bit CP/M laptop, the Epson PX-8 is exactly that. It runs CP/M from ROM and uses a RAM disk for storage. (Strangely, it uses a cassette for mass storage.) I had one of those, too, once upon a time... and I also don't know where that went Tom Wilson

REX2 was an original attempt at a module that supported CP/M. It did not survive! I think I made 6 of them total. Those 6 worked fine as a standard REX. With only 128k of RAM, it would have needed some pretty fancy software to turn a flash chip into a read/write disk drive. REXCPM takes a

Speaking of the REX3, was the REX2 ever released? It sounds like it would run CP/M and have flash storage: http://bitchin100.com/wiki/index.php?title=REX2_-_custom_REX_for_CP/M_support Jon On Wed, Mar 11, 2020 at 2:30 PM Tom Wilson wrote: > Kids are great for that. I had my daughter crimping
