using new technology on old machines. Was: PDP-12 Restoration at the RICM

[Simon Claessen]

as long as it is done in a way that it can be restored to its original, i have no problems in using newer technology in older machines. we have a alix sbc build into our tek 4002a 
for demonstrational purpouses, all done without damaging or altering the original machine.
