HP2000 fans... alert!

I have come across a stash of 12920/12921/12922 mux card sets. These are the cards that are required to run pretty much any version of HP's Time Shared BASIC. I know some of you are working on getting up the dual CPU versions of HP2000/TSB, but a lot of people here have just one CPU. These people could get HP2000/E up and running - that version works on just one cpu, and no special microcode is needed. I know that the 12920/21/22 mux sets are pretty difficult to find, and as I said, they are required. If you ever want to get TSB up and running you should get in on this deal. Most everything else needed to put together a TSB system is still fairly available, except these mux sets which are quite rare. The guy who has them will want real money for them. I suspect he will want somewhere in the ballpark of $100+ bucks per set (it's a 3 card set). I'm going to buy a set to use for a 2nd TSB machine, plus another set for a spare. These cards probably wont be easily found again as they've all but disappeared (to my knowledge). I don't believe his mux sets includes the distribution panels, but the pinouts to build your own cables are well known. If anyone is interested, please let me know off-list immediately as I'm getting an order ready to snag them. Jay West
