I went to our dungeon with defunct equipment  and  I found out that it was
PDP15. Another machine that used this was a machine build by Polish pioneer
of minicomputers, Karpinski, around 1965 (?); it was a contract for the physics
department of the University of Warsaw. At this time they couldn't afford 
anything commercial, so they hired Karpinski. This machine still works, 
maintained by a dedicated engineer, even though they are getting some IBM PC
that are comparable in computational power to it (there was a front page article
in Wall Street Journal about the PC revolution in Poland).
