Truely rare:
PDP1/4/5/6/9 Collectively there may have been 3000 total.
<PERQ 3a, PERQ 2T4 (a lot rarer than the 3a, BTW), HH Tiger ?, AMT DAP
<(?), Tandy Deluxe CoCo, PDP11/74, HP95-C (OK, it's a calculator), Philips
11/74, there were at most 4 possibly 5 constructed and all 4 within DEC
were disassembled and used as 11/70s or scrapped. The fifth was at CMU
and that was also scrapped. NEver made it to production as it was more
powerful that vax780 and would never pass EMI/RFI standards that were
appearing.
