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. Bob Stek
