The problem with the straight replica is that the parts for an RX8E have
I do have an adaptation of the RX8E for modern components and Posibus. I
have built one of those (but it has nothing to do with DEC board physical
sizes). Another list member and I are hoping to get around to debugging the
prototypes "real soon". You'd need an M8350 (or Posibus PDP-8) for one of
Another possibility would be to "fix up" the RX8E with modern (well,
obtainable anyway) chips, and make that. (But I like the Posibus idea
better, as more PDP-8s can play.)
As to the cost, it's pretty reasonable. Could probably be done for about
$12-$15 or so per board, in reasonable quantity (say, 30 units). Plus
parts, shipping, etc. probably still under $50.
(We paid more for the prototypes, but then we didn't spread the cost over 30
