Steve,
I remember those old 300M units. A real pain in the as* to get everything aligned and about the time you got them working right a head would crash. Boy does some of this stuff bring back things I had forgotten about. I went and found the two old aluminum memory cards that I did save. Each held 64 words of 44 bits each and there was a left and right hand card. It took 200 of them to make a module and they had a card writing machine that would normally sound like you were in a machine shop where they were using presses and about half way through each module it would eat a card and then you had to take everything apart to get the bent card out, replace it with a new one, figure out in binary what needed to be written on that card and then let the machine start again. Some of the big offices had a three man crew that did nothing but write those cards and they had three shifts.
