[Simh] Alpha ES40 emulator

[Tim Stark]

Folks,

 

While I am waiting for SIMH version of Alpha emulator, I tried ES40 emulator
from Sourceforge.net.  I converted ES40 repo to git repo and uploaded it
into my github. 

 

I tried to compile but got many errors.  I figured them out and applied
SMR11's sources to my git repo and successfully compiled it on Ubuntu 17.10.
You have to execute reconf first to rebuild autoconf files to be compitable
with Ubuntu 17.10's autoconf packages.  I updated it on git repo done.   I
found SMR11's video clips for how to install OpenVMS Alpha 8.4 system on
YouTube.

 

I tried to configure NIC on es40_cfg but it crashed after I selected 'nic'.
I have to manually enter nic block into es40.cfg.  I tried to started es40
emulator and it crashed after I selected one of NIC adaptors. I got opening
adaptor error. 

 

I have some trouble with finding cl67srmrom.exe through Internet.  I tried
cl67srmrom.exe from V61.iso but it did not work so well.  It crashed after
printed PALcode message. 

 

I searched for good version of cl67srmrom.exe through Internet and got
binaries from Sourceforge.net and replaced it.  I successfully booted SRM
firmware into POO>>> prompt.

 

I tried cl67srmrom.sys and it failed to boot.  I examined its executable
file and it looks like MOP header.  Does anyone know any MOP header specs?
Look at first 256 bytes of cl67srmrom.sys:

With good version of cl67srmrom.exe, I successfully booted into POO>>>
prompt.  

 

I successfully loaded and run OpenVMS Alpha 8.4 and followed installation
prompts. 

 

During installation, it crashed system with access violation error.  I think
that ES40 still have some bugs with some opcodes and NIC configuration.

 

Does anyone have any HCORE tests for Alpha processors?  I am looking for it
in long time! 

 

Thanks,

Tim
