ebay: Are these PDP-8 boards?

Apologies if this appears twice -- Replies to mail from cctalk seem to vanish into thin air. From: "jim s" I'd go a step further -- many of those modules were never part of the RS08 that the backplane implies. I'm quite sure there were no Mxxx modules in an RS08. The Gxxx are right, as are the Bxxx. I don't know what an S200 is, and I don't see one in the RS08 documentation (maybe it's an S206?). My theory is someone used it for a while as a convenient place to store some Mxxx spares from a PDP-8/I. Here's the RS08 module list from table 5-2 (on page 5-2 of DEC-08-HIEA-D, aka RF08_PrelimMaintMan.pdf): B133x2 B134 B135 B137 B152x3 B165x2 B172 B212x2 B301x3 B312 B611 B683x2 G085x4 G284 G285x4 G286x4 R002 R302 R111 R302 R303 S206 Vince
