Hi, The Z-RAM board from Madison Computer has been discussed here before. It turns out there's another CP/M system for PET/CBM: the SoftBox from Small Systems Engineering. I have started a page about it: http://mikenaberezny.com/hardware/pet-cbm/sse-softbox-z80-computer/ The SoftBox is an external unit that attaches via IEEE-488. It's actually an IEEE-488 controller itself. A terminal program is loaded on the PET that makes the PET act more like a peripheral. The PET waits for SRQs with commands from the SoftBox. The SoftBox controls IEEE-488 peripherals like drives and printers directly. It also has an interface for a Corvus hard drive. When used with a Corvus, the system is very fast. It's a nice CP/M system. I've spent some time disassembling it and have been working on a CBM-II port. You can find all of that at the link above. I have not found anyone else that has a SoftBox. If you have one, I would like to hear from you.
