I vaguely recall that we sold a few cassette cables to early PC users, and I don't recall them being refunded, so they just might work. I'll never know, the only IBM/Intel cpu I have is an old AT that my fiancee got for free at the Trenton Computer Festival and wants me to use to build a word processor for a friend of hers. (I'll probably keep the thing and use my old workhorse nameless 386 for the job despite my memories of my first Linux installation on the beast from an 18" pile of 5.25" floppies -- or perhaps because of those memories). There is _other_ IBM hardware I _am_ interested in -- I'd sort of like an old RT/PC and I _really_ want an RS/6000 with decent expansion, though the ones I want are definitely too new for this mailing list. -- Ward Griffiths Dylan: How many years must some people exist, before they're allowed to be free?
