Hey Mac, I assume we've talked about this in the past, elsewhere (youtube). Maybe I'm wrong.
Yes, the Vixen is an incredibly rare machine. There weren't many made at all. It was the last thing that OCC made before they really went out of business for good. If in fact, you are the same Mac that I've spoken to in the past about Vixens, then you probably know that I had been searching for one since they were released, and only rather recently managed to obtain one.
CP/M software is very portable - most things which don't require hardware-specific calls (i.e. those which work directly with the OS's device definitions such as console, printer, disks, etc) will work just fine.
However, the vixen will only boot vixen disks. Once booted, it will read any other Osborne format natively, and with MediaMaster, can read hundreds of other formats of disks. However- if those disks contain useful software for some other architecture, the jury is out on how viable the code will be on the Vixen. Things like serial port access often require tailor-made overlays or inserts for that machine's hardware, so a program can control it directly (rather than having to reconfigure a card's switches or jumpers for other baud rates, or things like that).
What you really need is:
- a 360k disk drive
- a DOS PC
- teledisk and imagedisk software
- about a dozen blank disks (to get the full software suite)
- a disk image for IMP (Irv Hoff's Modem Program, lets you Xmodem/Ymodem/etc code from another computer)
If you'd like, I can send you a complete set of master disks, all software known to exist for the Vixen in the online image formats, plus a working IMP disk. All I ask is to cover the cost of the disks and the shipping. Probably a total cost of about $15-20.
