Discontinuation Notice

ES40 emulator development has virtually been halted since 2009. The lead 
developer of ES40, Camiel Vanderhoevenis developing both Freeware and 
Commercial Alpha and VAX emulators for Migration Specialties.

FreeAXP  is the Freeware Alpha emulator from Migration 
Specialties.

Avanti  is the 
Freeware Alpha emulator from Migration Specialties.

I (and the ES40 author) would highly recommend that you use Migration 
Specialties’s FreeAXP emulator instead of ES40 if you are just looking to 
successfully run OpenVMS on an Alpha emulator. FreeAXP is a stable and 
supported Alpha emulator for both OpenVMS and TRU64 and is available at no cost.

The lack of a Non-Windows host makes this a non-starter for me.  All I have are 
Linux and macOS systems here. I won't buy a Windows license to run under an 
emulator to run an emulator for an Alpha.  The limitation to 128MB of memory on 
the FreeAXP emulator is also a problem.  Being free, I realize I have little 
firm ground to stand on, but I just wanted to make it known that it's hardly an 
ideal solution for everyone.

I look forward if/when SimH has as good of an Alpha emulation as it does PDP 
and VAX.

I know that but FreeAXP runs on Windows only. I want to run it on Linux and
OS X systems. There are no free stable Alpha emulators available for Linux
and OS X systems.  Only ES40 emulator runs on them.

Subject: EXT :[Simh] Alpha ES40 emulator

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
