[HECnet] AXPBox

[David Moylan]

Are you using the latest version of his code? I only mention this because the Ethernet adapter code was updated 4 days ago.

I haven’t yet tried to spin this up myself, so I’m only commenting on what I’ve seen and some of the reported issues on GitHub and comments that phase IV seems to be more stable than TCP/IP.

Cheers, Wiz!!

It crashes on starting DECnet Phase IV. I installed from VSI's "ALPHA0842L1.ISO" and HPE's "OpenVMS_8.3_Alpha.iso". Same crash in NETACP in both cases. Guess we will have to wait for this to get resolved, unless this is a known issue for DECnet Phase IV on OpenVMS Alpha 8.x.

The key thing is the progress this represents.  The fact that you got it running at all would seem to put it ahead of Jonathan D. Belanger’s DECaxp fork.  I believe some folks had gotten ES40 to sort of boot, but I don’t think they got as far as any networking.  AXPbox represents a very important path forward for the OpenVMS Hobbyist community, and I wish the folks working on it nothing but the best!

In all fairness, you shouldn’t expect good performance from any Raspberry Pi that’s being used to emulate a DEC Alpha.  The commercial Alpha emulators really expect you to be running on a high-end system.

The DEC Alpha page on my DEC Emulation website has just been updated to reflect this news.

If anyone has any information on Jonathan D. Belanger’s DECaxp fork, I’d be interested.

It seems quite unstable in places.... and very slow.
I got it running on a raspberry Pi 4 with the 64bit OS.

 Not sure if you guys knew about this emulator forked off ES40, but looks promising enough.
