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.

Regards,
Mike
