Bus and Tag Telex drive listed (Ebay alert)

The same vendor which listed the CDC Keystone drives also has listed a pair of Telex drives with Bus & Tag. I don't recall who has the incoming 4341, but this would be a great and for the mainframe, compact half inch tape subsystem. I would check, but I believe this would have all you need

They both included ISA cards according to the auction, but I didn't see a photo or more details on which one. The top loading one would be nice. I remember when MPI was manufacturing a similar arrangement for DEC in Valley Forge. The ones that mount in a rack are a bit less involved, but the

Am I misremembering or wasn't denatured alchohol the recommended type when cleaning rubber type computer parts (i.e. rollers in laser printers). I thought isopropyl dried them out.  I don't know the affects on either other than that though.

Re: Compatibility of 1101A and 1101A1

Most often, a number past the letter meant the speed. Usually a 1 indicated 100 ns but I don't know if that makes sense for 1101As. I suspect it still means something related to the speed but I'm not sure what speed that might be. My guess is that it would work at some speed. Dwight
