Well, occassionally we stumble across something that is kind of unusual
at a great price! Yesterday at TRW, Dave (senior moment, can't remember
his last name but former member of this list) told me about a Heath 3400
microprocessor for sale. Turned out that the guy had the Heath
Microprocessor trainer AND and a mostly unbuilt (resistors only soldered
in the board) Heath I/O interface; both were in the original box and
included the original manual! I have seen very few of the Heath
interface units, and finding one that was essentially unbuilt was ...
inspiring :)!!!
