[edit] Removed x86 comparison

I removed the x86 comparison (again), because the naming of the AX and BX registers is surely a complete coincidence. On the 8080 and 8085, the registers weren't very general, and in particular A was available for a lot more operations than B. But on the 8086, AX, BX, CX, and DX are fully general-purpose registers, and there's nothing special about AX and BX to make them similar to A and B of the 2100. It's natural when naming four general registers to call them either A, B, C, and D, or 0, 1, 2, and 3. Given that there is no substantive similarity between the 2100 A and B registers and the x86 AX and BX registers (or EAX and EBX), a comparison or even mention is far too speculative for the main page. --Brouhaha 22:34, 20 July 2006 (UTC)

[edit] Comments

I can't verify that the 2114C ever existed. It's true there are specs and literature advertising it, but I've not been able to find anyone that actually had/has one.

I'm working on restoring an HP-2116A in my spare time. Feel free to use any pictures from the gallery that you like and/or link to it. HP-2116A Gallery

It might make sense to list the memory sizes in kilobytes as that's what most people expect to read these days. The listing is correct though, all HP literature at the time listed kilowords instead.

If anyone has more old HP hardware they want to get rid of, I'm happy to take it off their hands. (grin)

A more prominent link to some of the simulators would be nice. SIMH is probably the most popular free one.

The claim is that 2114-6 machines stopped being sold in 1970? My HP-2116A was installed in January of 1970, so I would imagine B and C models could have been sold for a few years after that.

Well... this is Wikipedia... feel free to edit the article. I don't think anyone will revert a comment like "Although HP also developed the 2114C model, but it did not appear to be sold before the line was retired" or something like that. I added the sole SIMH link because it's the only emulator that I've personally used, but again, feel free to edit the article. Articles like this one are tough because proper "Wikipedia"-proper references are tough to find on the web and lots of libraries seem to throw away any pre-1980 computer books (that's my experience anyway) which might be used to reference old architectures like this. Maybe Jay West (or yourself) needs to put up a HP 2100 history web page on classiccmp.org that can be referenced by Wikipedia. Thomas Dzubin _Talk 13:13, 28 March 2007 (UTC)
