New 3000 simulator looks back, not ahead

Hp2112bCommunity members on the 3000-L newsgroup have been examining a new entry in the emulation of HP hardware. However, this simulator creates a 3000 under Windows that only runs MPE V. The MPE version of SIMH — a "highly portable, multi-system simulator" — is a Classic 3000 simulation, not something able to run PA-RISC applications or software.

Some 3000 users are embracing this software though, maybe in no small part because it's free. It's been more than 15 years since HP supported MPE V and the CISC-based systems that launched the 3000 line starting in 1972. One of the experts in PA-RISC and MPE/iX computing, Stan Sieler, briefed us on what this freeware simulator can do, and what it cannot  — in addition to not running MPE/iX.

Currently only Charon from Stromasys runs PA-RISC. Thus, the SIMH runs only the Classic HP 3000. At the moment, it’s an old version of MPE V (Q-MIT, release E.01.00)

And, the machine probably has no networking support. It probably has some kind of serial datacomm support, but I haven’t looked at that yet (all my use has been via the simulated console, LDEV 20).

I’ve put several hundred CM programs on the “machine” to see which will load and run. Many won’t, because they use newer features (e.g., FLABELINFO intrinsic which came out on the T-MIT with the Mighty Mouse).

So, you ask, can you put a newer version of MPE V on the emulated 3000?

The answer is, I don’t know. If I recall correctly, the machine isn’t emulating (yet) the “Extended Instruction Set,” but the authors claim MPE has a run-time emulator for them, so perhaps that won’t be a problem.

It comes with a version of MPE V, if you download the two packages that the release notes file mentions.

It’s fast. On my Mac, it runs CPU bound stuff about twice as fast as a 400 MHz HP 3000 would.

This is classic software running on classic hardware, so it's strictly for the hobbyist. Or someone who still has MPE V apps running their company. The software is downloadable from Trailing Edge in a pre-compiled .exe file.

The discussion has already generated 40 messages on the 3000-L, easily the biggest discussion of the year.
