[Info-vax] Use SimH/VAX to boot infoserver software?

[Timothy Stark]

You can dump 256KB rom image by using command on SRM prompt

>>> Examine /p /l /n:ffff 20040000

Note: if it uses 512KB ROMs, then use /n:1ffff instead of /n:ffff.

I will write a program to convert output to binary image file.

I do not have that model of VAX.

Do you have a utility or a script that can be used to dump that firmware
image in a format that SimH can use in the case someone wants to donate it?

I would doubt that the MicroVAX 3100 and MicroVAX 2000 would be similar
architectures.

The MicroVAX 3100 supported different memory and I/O configurations, some
models had 2 SCSI adapters.

https://www.openbsd.org/vax.html

The drivers in netbad and /or openbsd may give enough information to add the
emulation of the hardware for the MicroVAX 3100 models.

Being able to implement an Infoserver on a small commodity computer would be
very useful.
