Re: [Simh] EXT :Re: DEC Alpha Emulation

I hear you. My point was it only failed the corner cases of failover, so I think it would have made it to logs. And that should have been good enough. Not perfect, but in practice it would have worked and it would have simplified things immensely. And not having the Adaptec support was in

Re: [Simh] EXT :Re: DEC Alpha Emulation

Now that you mention it, I was mainly thinking about the video cards, which aren’t fully applicable here. Though Network was another area besides disk where I remember it being a bit of a challenge. I wish I’d known that an Adaptec 1542 was an option, finding a card I could afford was a

Re: [Simh] EXT :Re: DEC Alpha Emulation

Be careful. The comment about many of the pci boards were only NT while that is true really is somewhat different. For instance both vms an tru64 (and FreeBSD for that matter) will all boot and run fine with an Adaptec 1542 controller (the 500au in my office only had same in it) The SPD

The Alpha target is the Digital Personal Workstation (PWS) 500au [codename: Miata], which qualifies as a single user workstation from a minimum licensing perspective. Bob Supnik had one in his possession, and gave it to me to do comparisons. The Miata has both ARC and SRM firmware
