I didn't know of its existence before, but apparently Konami used the HP 64000 as a development tool for their MSX (and maybe other system) game titles. It's mentioned in an interview with the programmer of Metal Gear 2 Solid Snake.

From what I understand the HP 64000 was used to emulate hardware and prototyping micro computers. It only emulated the main micro processor and RAM, but had about a dozen internal slots, called "Emulator pods" that could be used for interface purposes.

From the HP 64000 wiki, it had these "pods" available:

Model Remarks
64191A Emulation Probe Motorola 6805
64202A Emulation Probe Intel 8080
64203A Emulation Probe Intel 8085
64212A Emulation Probe Motorola 6800
64213A Emulation Probe Motorola 6802
64215A Emulation Probe Motorola 6809
64223A Emulation Probe Intel 8086
64224A Emulation Probe Intel 80186
64226A Emulation Probe Intel 8088
64232A Emulation Probe Zilog Z8001
64242A Emulation Probe Motorola 68000
64252A Emulation Probe Zilog Z80
64256A Emulation Probe Motorola 6801/6803

On MSX.org there was also a discussion about it with an interesting remark about slowdown in MSX games, relating to the HP 64000 Z80 pod:

Quote:
Fantastic! And that explains why all Konami megarom games always seemed to be designed for a machine with a faster Z80 processor, thus run on 3.57MHz MSX machines skipping frames constantly: The 64252A Z80 emulator pod had only two possible speeds:

1) 3.6MHz without waitstates
2) 4MHz with waitstates when accessing the memory


Seems like an interesting machine from a historical perspective. I see it's not available in MESS, so this is just for documentation purposes. Maybe it makes for a good candidate to emulate somewhere down the line.

And lastly the "very sexy" centerfold image smile

The 64000 uses a custom HP SOS processor. It's may be the same as the one used in the HP 9845. There is a fair bit of technical information on it on bitsavers, and I own a couple of them as well as have the software. http://www.hp9845.net/ has a bunch of info. I thought someone had simulated it, maybe I was thinking of the HP80.

Lots of people used the HP 64000, back in the day. It was probably the ultimate Inline-Circuit-Emulation solution for the time.

I read in an interview that their best selling games at that time for msx and nes sold in the range of 600,000 to 1,000,000 copies. That does put things in perspective.
