Dave -
Your timing is good for asking about a ProcTech tape archive. I've been
working with another Sol owner and will soon have a CUTS programs CD-ROM
(just use a portable CD-ROM player in place of the cassette player) with as
much of the original software as it's been possible to find (TARG, BASIC5,
TREK80, FOCAL, PILOT, etc.). I also have a tape from Proteus, the ProcTech
users group, which I can send you immediately. Email me you address and
I'll pop it in the mail.
