I bought the Tek 4051 on ebay today; Jason brought it to my house and it works perfectly, with about a half hour of programming instruction my 12 old daughter was plotting a cat face.
https://www.facebook.com/Thelma.Franco/videos/10154277153852670/ I would like to get in touch with other users of this first personal computer, and find additional resources. Do you know where I can find an archive of BASIC programs for this? Has anybody built plug in cards in the back, mine came with a realtime clock and a "file manager", I do not know what that one does. I have some Tek scopes with IEE-488, and I will see if I can get the IEEE interface working. There was a DC300 tape in the machine: biorithm craps blackjack artillery tanks weatherwar The belt is broken in the tape, I have ordered some new DC300's and will transplant the tape. Any resources will be welcome! Randy
