This is a Soviet PDP-11 clone. Possibly a PDP-11/34 clone.
Actually, the very SM-1420 Elektronmashevskogo performance (because there were more Polish), see the processor with the keys and indicators, higher processor - SM5300 recorder, below the processor memory module (2 MB - it's just a miracle, so even with the cache module!), Left - "package" drives the Bulgarian performance (DP: in rsx11m or / dev / rp in Unix), they range from ESovskoy, the volume of 20,000 units 512K, ie 10 megabytes. Package replacement, very comfortable, I had a set and a set of rsx11m DEMOS-16 (UNIX), I change them as needed. Later Dima Pryanishnikov developed and made an IDE controller for UNIBUS, and paketniki turned off, and instead worked some old either 40, or 80 megs of WD. By the way, rk-shnyh drives three-phase (!) Food, they have three-phase spindle motor akkurat ... The fact that the CMEA countries flogged PDP-11, supplies of which were strictly prohibited, there is a whole article PDP-11S behind the Iron Curtain, translation can be found here .
