Hi,
as far as I can remember, there is and was no NCR Memory Chip 7412.
7412 is most likely the date of production. Year 1974 and Month December (12).

Thanks for the 605 web site. I was a corporate specialist on the 725, 721, 8250 and 8270 and traveled all over fixing them. Knew it well back in the day but that was about 40 years ago. Brought back many memories. Rich

This Link "http://www.geocities.ws/NCR605/" is still working, but when you are reading this site over the different pages, suddenly you are spattered with advertising, porno and other mess.

I saved the pages, removed every javascript-rubbish and put the "cleaned" pages on my server.

You can now look at the pages at "busstech.de/ncr605".

Regards Heiko

That is an excellent read!  I hope he did the follow up with Don Eckdahl, and that someone can find it.  One comment about Carl Rench's recollection, the man in the 80's that he mentioned as Tom Jang was in fact Tom Tang.  I worked in his organization for a lot of years.
