This is pretty cool. I have OpenVMS VAX 7.3 running under SIMH clustered with OpenVMS Alpha 8.3 running under FreeAXP. I'm using bridged TAP network adapters for each of them. DECnet, TCP/IP, LAT, cluster comms all seem to work fine so far.
BTW, I notice that FreeAXP can also mount SIMH disks, so I gather they use the same simple container format. (Of course, I don't do that while they're also mounted via clustering I know what havoc that would cause.)
FreeAXP reports about 198 EUP while pegging one processor at 100% on my 4GHz Core I7. If one EUP is honestly 700K instructions per second, then that's about 138M instructions per second. Not exactly the supposed 166M of the real thing, but not bad. However, I did give up on having TCPIP$CONFIG generate an SSH key. I didn't want to wait for it...
A VAX under SIMH can have 512M of memory, but a poor Alpha under FreeAXP is limited to a measly 128M. I gather it's going to be doing a lot of paging.
SIMH can detect when VMS is idle when emulating a VAX, but I gather FreeAXP cannot do so when emulating an Alpha. I seem to recall dim memories of idle being totally different between VAX and Alpha (or was that an even earlier VMS internals change that I'm dimly recalling)? FreeAXP constantly pegs one processor at 100% usage, even when idle. Can anything be done about that?
malmberg March 24 2018 Probably. More people hang out on the comp.os.vms newsgroup.
vaxpert March 23 2018 I have a PE42A and other Alpha system stuff for sale. I'm in So California. Any interest out there?
goodbyespy February 27 2018 To Prohorenko. Please, visit group OpenVMS in the ok.ru
peteherrera February 24 2018 How much does it cost to buy a complete OpenVMS hardcopy documentation set of the latest version
prohorenko February 17 2018 Please help to obtain the license on OpenVMS
malmberg December 12 2017 HPE only makes the most current version of OpenVMS Alpha / IA64 /VAX available to hobbyists. When I had access to the Alliance 1 program it was the same. No public downloads are allowed by HPE.
nmbonao December 08 2017 Is anybody knows OpenVMS 8.2 version downloadable version? or CD copy? Thank you very much

malmberg September 10 2017 https://sourceforge.net/p /vms-ports/wiki/VMSInstal lation/ For the most part just use VMS 6.1 media instead of 7.3. But why run the older release?
DoeveR August 07 2017 Where can I find the write up on running VMS 6.1 using the simh emulator?
