FRAM71 : Threads, Articles, Presentations, Manuals, etc.

[Howard Owen]

I imagine 1AAAA machines are rare. I've never seen an HP71B eBay auction that called out that version. (Some auctions omit the ROM revision, of course.) With a FRAM71, you can have your collector's cake and feed the enthusiast too.

If you do have one, and would consider swapping that old, troublesome early ROM 71B for a modern, updated 71B with shiny new ROMs, please drop me an email.

Why do you want a 1AAAA? Doesn't it have the battery drain issue?

I assume the hardware is identical?

Or do you want the whole set ?
