OTD 1975, Digital announces the #PDP-11/70.
With up to 4 Megabytes(!) of memory.Princeton's PDP-11/45 had 80K bytes of memory. Ran UNIX just fine.
@aka_pugs The 11/74 was cancelled because it was to good compared to contemporary VAX models.

i was trying to remember the boot sequence for a PDP 11/70 from disk.
i think that the 21 addr switches were an octal 17773052 but can't remember what we did with the 7 switches on the right. it was four movements, ending with "start"?
anyone remember better than me?
I guess these switches were, among others, used to read and write memory.
I had to program this computer in binary (not assembler, binary) when I learnt computer science some years ago.
In my memory, the keys were shades of blue.
