I guess you should hold off on buying his PDP8 stuff
Between what Eric Smith, CHM and others have I don't think I need
any of his PDP-8 stuff. The Royotron stuff is much more rare since
the punch is used in DEC reader/punches but the info in them isn't
in the DEC service docs.
I normally don't say anything about getting stuff run up on me, but
paying $150+ to have the seller turn around and try selling scans for
$10 was depressing (only good thing is he claims 200dpi, which
won't be all that great).
