HP-71B Early Date Code
Message #1 Posted by Gordon Dyer on 20 Aug 2002, 7:04 p.m.

I have an HP-71B with date code 2401A00135. This is 1 week earlier than shown in the early date codes page. The VER$ is HP71:1AAAA. It still works ok but is in tatty condition!

Wow.

Does anyone else have one with that ver$? I thought BBBB was the first!!! Is this a prototype?

It is definitely not a prototype, or at least it looks like it was a full production unit, but now very battered and tatty. I can send photos if anyone is interested.

Yes, I'd like to see some photos of it. Thanks in advance.

Does anyone have information on bugs in VER$ 1AAAA ?

It appears that version AAAA wasn't used for very long, as I have a 71b with a serial number of 2409Axxxxx. Made just 8 weeks later, with a ROM ver of 1BBBB.

My earliest non-prototype has a serial of 2410A00149 with VER$: 1BBBB. I have one (prototype) with serial 0000A00035, which shows for VER$: TI%RM4-HP71:0AAAA, but because of the 0000 serial I do not know when it was made.

Yours does seem to be a prototype and is earlier than mine.
Perhaps Dave Hicks will now update his earliest date code page?
