I have recently starting writing my own Alpha AXP emulator (a 21264). The ones out there are great, but many of them were not designed to be multithreaded, and have this kind of hack threading into the implementation. The one I'm writing, will be as accurate an implementation of the 21264 as I can make it. It will be able to execute 4 instructions simultaneously, just like the real CPU. I'm also going to take a page out of the alternative meaning of the acronym RISC (Relegate Important Stuff to Compilers). I have seen quite a bit of other code that has tried to best-guess the compile, but using masks and shifts and whatnot (it also make debugging harder). We'll see how far I get, but I'm having a ball writing it (I always said, that if I were not writing code for my job, I'd do it as a hobby -- so that's what I'm doing).
Not booted yet. There is quite a bit of coding to be implemented, I have parts of the instruction, integer, floating-point, and data cache implemented and tested (the IEEE floating point instructions passed 100% of the IEEE test cases). I have not yet, introduced threads (and each CPU will require 9 of them). The system interface is also not yet implemented. The system interface contains all the devices associated with a computer system (disk, memory, network, console, etc. - each being yet another thread). I am hoping to have it booted from the SROM (pre-console system) in the next few months.
I you want to see what I have done, thus far, you can go to GitHub and search for DECemu.
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?
