Sooo, super duper hot? Looks like a bitchen box, but if it really is that hot I might reconsider my machine watch list.

I'd say it's comparable to an itanium or sparc system's heat.

Itanium, yeah, but MicroSPARC is pretty cool. Pretty slow, sure, but it is pretty cool.

There was a thread on here a while back about firmware locking out a second CPU unless you paid HP to send an engineer to unlock it (or obtain a new license?)

I assume you did not run into this issue, which bodes well for the prospect of upgrading mine. Can you comment?

Just out of curiosity, what should one expect to pay for an HP-UX machine like this?

A single (dual-core) CPU system shouldn't be more than about $200. For dual dual-core, PA8900, and extras, it can be a lot more.

Thanks mattst88, I'll do some searching on ebay and try to learn more.

Similar to how SGI stations excel at 3D and graphics work, what are the HP RISC architecture's traditional strengths supposed to be?

Okkkk then... the dual socket C8000 systems on ebay are all over a grand... too expensive for a play-thing.

EDA, CADD and similar high power technical stuff. The market segments kind of overlap with AlphaStations, but PA-RISC was generally a FP monster.

The single cpu 8800 model systems are the inexpensive ones, the 8900 and dual 8800/8900 are more expensive. I got both of my systems for less than the price of a comparable dual 8800.

Yeah I just had to take the time to unscrew it since the hex screws have little spikes in the middle and my wrench was too long so I had to remove the chipset heatsink to unlock the cpu.

The full story to that thread is that the guy turned out to have a PA8800 CPU without L2 cache (only the 768k or L1) which was itself not dual-CPU capable. So, it wasn't that HP was explicitly disallowing upgrades or anything, just that the lowest-spec'd CPUs aren't dual-capable.

Edit: I thought it'd be a good idea to update the linked thread, but I see that I did... back in November.

HP does limit the setup in the firmware to a certain extent - I can't "chip" up my B1000L any faster because the PROM locks it out if I do anything to the multiplier jumpers. This includes "legitimate" settings (ones used by other members of the same family).
