The DEC Alpha Emulation Webpage
Last Updated: 02FEB2018
- (2018-02-01) Working on major page updates
- (2006-01-22) SRI is working on an Alpha emulator
- (2003-04-03) Added Alpha page.
It is now 2018, and I really need to rewrite the introduction to this page. I'm currently looking to reduce my reliance at home on vintage hardware, and to lower my electricity bill. I've started using SIMH/VAX heavily, and would love an Alpha emulator for the Apps that I can't move over to SIMH/VAX. Plus from what I'm seeing, current Intel-based systems can emulate an Alpha-Based system faster than the fastest Alpha.
At this point I don't know why anyone would want to emulate an Alpha. If you are a hobbyist looking to run OpenVMS, take a look at the VAX emulation available, or buy an inexpensive used Alpha. Having said this I've been watching the ES40 emulator with great interest as at some point this will no longer be true, and at this point it is the emulator with the greatest promise for Hobbyists.
If you are a commercial user I would seriously recommend looking at an upgrade to Itanium if your applications will run there. If not I would recommend looking at one of the newer models of Alpha that are still available.

Step 1. Obtain an emulator:
- Work is being done to add DEC PWS 500au support to SIMH. Current efforts center around implementing the emulated hardware required to be able to boot the the SRM prompt.
- SRM support is required to be able to boot OpenVMS or Tru64.
- ARC support may come later, but would require VGA emulation. ARC support is required for Windows NT.
- Anyone interested, and able to assist with the effort should contact David T. Hittner via the SIMH email list.
processor simulator (now at v3.0e)
appears to implement an EV4 CPU.
- SimOS at Stanford, also see this FTP site, and this FTP site. (Dead Links)
- CHARON-AXP from Stromasys (originally SRI), supports OpenVMS, and Tru64 UNIX
- PersonalAlpha from Emulators International, a subsidiary of SRI, runs on XP and is available for personal use. It emulates a system with 96MB RAM, Ethernet, two disks, and Ethernet. Based on the information they provide on the website, it appears that they have limited the speed, and with it only emulating 96MB of RAM, you will run into serious performance problems there. I've not tried this product out as I prefer to run OpenVMS on real hardware.
(no longer available)
- AINT (Dead Link)
- Virtutech has some sort of model libraries that emulate an EV5.
(Virtutech is no longer around, the link points to Wind River)
- ES40 emulator
(development has been discontinued)
- FreeAXP from Migration Specialties
- Avanti & AvantiFlex from Migration Specialties
- Runs OpenVMS 6.2 thru 8.4
- Runs Tru64 UNIX V3.2C thru V5.1B-6/Pk8
- AlphaVM-Free (no longer available)
- QEMU is not able to run OpenVMS or Tru64 at this time (Feb. 2018).
Step 2. Obtain Installation Documentation:
Step 3. Obtain Software:
- OpenVMS 8.4 and select Layered products are available through the Hobbyist Program
- Tru64 UNIX - eBay
- WASD VMS Web Services
- Process Software's Multinet TCP/IP Stack is an excellent alternative to the stack that HP ships, and they offer it to Hobbyists with a valid OpenVMS Hobbyist license.
- Process Software's TCPware TCP/IP Stack
- Process Software's PMDF Internet Messaging
- Process Software's PreciseMail Anti-Spam Gateway
- Oracle RDB (OTN Account required)
Step 4. Obtain Further Documentation
Step 5. Adding Additional Software
