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 for hooking it up from what the listing says for two drives.
Located in Sacramento, Ca, would need freighting & shipping, as auction is marked local pickup only.
Hope someone saves them. Probably way more compact and less fuss the 3420's. I doubt anyone will find many 3411's which would be the next most desirable, since it also has a builtin controller if you get the 370 version. With the 3411, you have to watch out for IBM 36 or some such which looked the same, but only had a single Bus cable to the host. But I digress. the 18" x 18" x 18" block of steel you don't have to deal with in the 3803 and probably 900# of just the controller makes a lot of difference.
