  MARCH's 2 PDP 11/05 computers by Bill Degnan - 08/02/2009 11:01
On my way home from MARCH's computer museum I took home two 11/05's for inspection.

More on this later, but I was able to get one of them to read and write memory from the front panel, the other I was also able to get funcitonal aside from a stuck 7th bit in the 4K Core memory card.

UPDATE: THe system with the bad core does not respond to any front panel input, the "working" system today would not power off when switching the key to the off position.
