Can you guess what computer these logic boards came from?
The only thing I can say for sure is
1) They're not from a Digital Equip Corp computer that I have ever seen (not the right size)
2) The Philco PD993659 chips have a silscreen date of 1968, 17th and 18th weeks.
3) These boards are exactly 14 cm tall (not including the handles)
