Happy weekend, all! Latest updates on this issue: Identified and replaced a faulty 4116 DRAM (E204) on my MS11-L. After this, my small hand-rolled standalone diagnostic passes the full 256K. I'll post my diagnostic source over on my blog soon. After this repair, tried MAINDEC ZQMC, called

It has been almost two years since I visited this topic. But just before christmas i got around doing something about it. I interfaced it to the PDP-11/05 using an XY11 board. It seems to be very little information on the XY11 board saved. At least I didn't find anything. But the board is a quite
