The one on top is not legible, but the other two are HM62256...

Yes. I used it for nearly 25 years with absolutely no trouble, and then something happened to it. Now I think it's just that there was some kind of configuration problem, and it might be fine if I just put it back together and put it back in. It had a lithium battery which I removed, not needing it to keep memory outside the 71 anyway, and not wanting the battery to leak. I don't remember if my 32KB front-port memory still has the battery in it or not.

When the FRAM is ready to go (and when the house quits needing repairs so I can afford the FRAM), I would like to get that. I use my 41cx every day though, whereas I seldom use my 71B's.
