[HECnet] AXP Emulation

[hvlems at zonnet.nl]

What I meant is that the os fit was done in firmware. Not, like the VAX, where the instruction set was designed to match demands from the os. IIRC the queue instructions aren't part of the Alpha instruction set. 
On or off topic? It's Digital Lore, right :-)

Correct, Windows started off on four platforms so the intimacy of VMS with the VAX was just not there. But VMS was a lot farther away from Alpha too.

I don't think that's accurate.

Most operating systems are not closely tied to a specific platform.   And in the case of VMS, the Alpha architecture had some specific attributes that were meant to make porting VMS easier.

I agree.   Alpha architecture was done with a posteriori and first-hand 
internal knowledge of VMS and where it was headed / what it's customers 
needed.   I had a pre-release AXP Architecture Handbook which would 
confirm, if I could lay my hands on the tree ware.

But this is OT, I suppose.
