Thanks for the response , the Heathkit ET 3400 is a good trainer . The kx-33b
had only data switches and I am guessing , possibly only 16 nibbles of ram .
Not much you could do with it but I thought it looked interesting . I once saw
an add for it in the December 1979 issue of Popular Electronics page 117. I
also ran across an add for the NRI computer I had mentioned earlier PE. 3\77
Pg. 37 from the add it looks to be called a model 832 .If anyone has the
chance to go to any computer shows\auctions lately and has seen these type of
computers I would appreciate hearing from you .
