Hmm. The reference to the 1401 and 36-bit words is wrong. The 1401 was a character machine, with each location consisting of 6 data bits, a word-mark bit and a parity bit. Based on the following reference to the 36-bit words of the 701, perhaps that was what was meant. Yes, I programmed a 1401 in autocoder. It was my second computer and second assembly language. By the way, it is possible to see a live 1401 at the Computer History Museum in Mountain View if you are there at the right time. The smell of the mechanical card equipment sure brings back memories.

Magnetic memory picture brought back memories (pun intended). Lucky enough to work for Dr An Wang at Wang Labs in MA.  Dr Wang is credited with the write-after-read which made magnetic core memories possible.  They were still used in some of the machines they were building at the time (yes I am that old).  When you're a young technician and have desktop programmable calculators and machines that ran BASIC readliy accessible to you, very cool indeed!


And YES, core memories were actually repairable.
