I have many expansion cards dated 1969 to 1974 using the Tektronix 72 pin expansion bus which I believe is present in the 4023 smart terminal (AKA 8008 CPU microcomputer). I have the expander/debugger card, many ram cards, serial IO and others. I also have dozens of proto boards for this bus. Some of the cards I have were designed or modified by the engineer at Tektronix as this was his personal collection.
I don't know the market value of these pieces of gear but I do know they are very rare and information on them is extremely hard to find, as is any of the terminals that can use them. Feel free to drop any information you may have on these or make me an offer on the lot. I don't want to piece these out - I'd rather sell them all together.
