The page for the PDP-10 was the best of the pages I have, and is the original 
page for the site.  As a result it needs a lot of updating.  It looks like even 
the bit savers links need fixed.

I just took a look at Lars page, it will definitely help, and I need to add it 
to my list of links.  I also see that he has updated the link to my page. :-)

Why is the page for the 10 so hard?

Thanks for the information Dave!  I’m glad to hear it’s still being worked on.  
I can well imagine what a pain the firmware is, especially if you’re trying to 
support both the SRM and ARC firmware.  I wish I could help.  From my 
standpoint, getting SIMH to boot OpenVMS would be a big deal.  

Are you working to support a specific platform?  I’m curious since not every 
system supports SRM or ARC, and many of the PCI boards were only supported by 
Windows NT.

Would you like me to put a note on the webpage for anyone interested in helping 
to contact you via the SIMH mailing list?

Re: [Simh] DEC Alpha Emulation

[Hittner, David T [US] (MS)]

Well, Migration Specialties is where the developer of ES40 went, anyway. :-)

I'm working on the SIMH Alpha simulator. It is quite a complex beast, where the 
firmware required to power up the system to the chevrons (>>>) is an operating 
system of small Linux complexity even before you can try to boot OpenVMS, TRU64 
or WinNT.  I think the simulation currently runs some 56 billion instructions 
before encountering a missing hardware simulation, and it's nowhere near the 
chevrons - and hasn't even built the OS interface block or the FW-level device 
tables yet.

If anyone would like to help with the Alpha development, I wouldn't say no. It 
takes a long time to figure what the RISC firmware is trying to accomplish. :-)

Zane,

just had a look at your Alpha page, and noticed that you missed an emulator:
FreeAXP / Avanti from Migration Specialties, 
http://www.migrationspecialties.com/
This is where the ES40 emulator went, AFAIK.

Betreff: [Simh] DEC Alpha Emulation

I'm in the process of slowly updating my DEC Emulation website, which has been 
largely stagnant since 2007.  The first page I'm spending some significant time 
on is the DEC Alpha page, as I'm curious to see what the current options are.  
In reviewing things, I notice that Alpha emulation was worked on at some point 
for SIMH (probably around 2006).  What is the current state of that work?  I 
had a quick google, and the most popular hit seems to be mirrored copies of my 
site.

Re: [Simh] DEC Alpha Emulation

[Zane Healy]

Thanks, I thought I had that one listed.  It’s there now, and the FPGA page is 
closer to being updated.

I’ll have to decide which I’m brave enough to tackle next, the VAX, PDP-11, or 
PDP-10 page.  The PDP-10 one will be the most challenging one to update.

Zane,

just had a look at your Alpha page, and noticed that you missed an emulator:
FreeAXP / Avanti from Migration Specialties,

This is where the ES40 emulator went, AFAIK.
