I have a developed a knack for finding homebrew stuff on ebay that's listed in a way that all of the title searching in the world wouldnt pull up, lol. This piece was listed as "Electronic parts board ics microchip tester development", lol! I had this feeling that for some reason there would be some extras included with this computer and sure enough there was, always makes these homebrew creations even better when they come with some of parts that builder would have had in his (or her) workshop. Speaking of the builder, the listing stated that the builder was a "microwave engineer designer that passed last year". Shame there wasn't some documentation with this computer.
Anyway, one of the crazy things about this piece is that it is shocking similar to this:
https://forum.vcfed.org/index.php?threads/8085-s100-pinsetter.1244676/
Same exact s100 vector board, pretty much the same circuit and pretty much the same jig, albeit wood vs metal. Mine is a bit later than the above one, looks mine is from around '84. What could this mean? Maybe this is a particular project from a magazine article? I haven't dump the eprom yet, still trying to figure out how to make that happen. Btw, what is up with the 4 pin connector? Why would someone yank the other pins? I mean even if that's all that was needed for serial (you only needs 3 for serial, right?) communication it would only serve to weaken the connection.
P.S.- Did anyone else think "ant farm" when they first saw this computer?
