Shortly I'll be building yet another HP2000 TSB machine, so I'm looking for
either of the following:

 

HP 12920B Asynchronous Multiplexer :

12920-60001 Upper Select Code Data Board 

12920-60002 Lower Select Code Data Board 

12922-60001 Control Board 

 

Or

 

HP 12920A Asynchronous Multiplexer: 

12921-60001 Upper Select Code Data Board 

12921-60002 Lower Select Code Data Board 

12922-60001 Control Board

 

Generous bounty and/or trades available for either of the above. Even single
boards of any of the above would be a big help.

 

Best,

 

J
