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. Allison
