[HECnet] AXP Emulation

[Sampsa Laine]

Why is SIMH so slow though?

As far as I can understand, one MIPS is roughly one VUPS, correct?

So how come I get 14 VUPS on the same host running SIMH whilst my Hercules install peaks at 180?

Are the architectures that different (obviously they are) or what is it?

This seems like a natural for SIMH, since it already has a large
amount of necessary prerequisites (a lot of device emulation,
framework pieces, etc.).

There is Alpha support in the development track version of simh.

Is the architecture well enough defined in
publicly available documents?   I would guess yes but I don't know for
sure.   Are there secret bits that are critical and hard to obtain?

The architecture manual pretty fully documents it.
