So, sorting thru stuff I came across this white elephant again. I never found anything to positively identify it but I always assumed it was some kind of buss extender. One board is fully populated with chips and the other connected together with a ribbon cable is totally passive. But this time I found the funniest thing about it. The passive end has a sticker on it with an expiration date. I have to admit I have never found an expiration date on any of my PDP or VAX hardware before. :-) bill
