It has been some time since I have been in contact with the BofA Museum Curator in SF. We live in Concord, CA where the only ERMA is located on the ground floor of the BofA building there. I will have to dig into my safe to pull the letter I have from them when I donated all the boards. As I said, they were missing boards and could not fire it up after they restored it. The person who was commissioned to find anything about the missing ERMA computers (which there was more than one ERMA) was Al Ziff (I think that was his name. He was retired by then. He was the lead person in charge of ERMA when it came to the Bank and my Father in law worked under him from the beginning. They had no idea how it was going to be used and that was their first project. Al found the only remaining ERMA in a BofA warehouse I think in Plesanton, CA. Then organized the project to restore it. The other 5 were destroyed.
There are many interesting stories when they first started and some of them were funny also. Al Ziff and two others of the original 6 spoke at my father in laws funeral and they had some very interesting things to say about it. Those guys stayed friend for many years.
My Father In Law was tasked (after the initial settling in) with working with the people that formulated the magnetic ink used on the checks so ERMA could read them. Also the "special" font. He also was in at the ground floor of BankAmericaCard which was the beginning of Visa.
He went on to also work with the Big IBM computers that took the place of ERMA later on.
He had a massive heart attack and had to retire. When he retired, he had well over a years of vacation and sick leave that he never took over the years. Back then, they could "bank" sick leave, and he worked for BofA well before WWII. After the war (he had two bronze stars), he returned to BofA.
I have seen modules of the prototype computer that became ERMA. In fact, My Father in Law was very much into electronics as a hobby. He had many parts from old computers that he stripped parts off of 9what a shame now!). I remember seeing a memory core with dozens of wires with little ferrid beads where the wires crossed. Maybe IBM????
Any way, I will look in the next few days and see if I can pull the letter from BofA.
Jim Carey was my Father in Law.
