another hidden pdp11

hello all, yesterday my wife and I emptied our garage(25 years of diverse things stocked inside).I found again my hp1000,I saw a vax8200,a a lot of things that suddenly made me rich :-))etc...and I found something I had totally forgotten ,bought a long time ago as a part of lot bought at the near army base:a Tektronix microprocessor emulation system,made of two (big!!!) racks a 8510 and a 8310.I opened them just to see ,and immediately I saw the two purple dec handles in the 8510.... A lsi 11/2 was here.I brought the rack inside ,removed the dust and spiders, connected to the terminal line labeled 'auxilliary' a VT320 and powered it up,after a few tests,I found the correct speed (2400 bauds) and got the odt, using the run/halt switch of the front panel. I has 32k of ram,the console is at correct place,but the fdc is not at 177170,so I doubt it can boot standart rt11.Unfortunately I found an error in the memory:bit 9 of the first 16k bank is stucked to 1,it may be only a ram chip (4116)to change,the 2nd bank is correct,a few test programs were ok. So if you see such a machine it can be useful. I'd like to find maintenance informations about the Tektronix boards. I'try to repair the mem board,and will continue to play with it.
