I’ve only just joined cctalk, so apologies for the delayed response to this
query from May, but I thought the information might be useful to others in
future.
I’m the person working on emulating MIPS workstations in MAME recently, and I’m
a fair way through getting the Rx3230 model to a fully
Interesting with those MIPS workstations.
Does the firmware (PROM) have any interesting commands?
Like 'pr_tod', 'init_tod', 'init' and so on?
found a PROM monitor reference in http://www.bitsavers.org/pdf/mips/

It is a DS1287
The issue is finding out what the contents should be, since it isn't
documented in the surviving manuals.
Some of this was figured out in getting the

If the MAC address is the only concern, you could fuzz it. Write a pattern
into the chip then if the systems prom monitor or BIOS shows the MAC
locate it. It's probably at
I have the same problem with a cloned MIPS machine, a Sumitomo
Sumistation SP300. The biggest problem with my machine is that the
NVRAM holds the ethernet address. If it goes flat, there seems to be
no way to reprogram the NVRAM. If you find any solution for this,
please tell me.

I pulled the frame buffer out of my 2030 and got up as far as the
monitor on port 0 at 9600. My NVRAM is dead so I'm digging around
trying to find another DS1287. The

Some useful information in there, but I have the original MIPS keyboard
and mouse.
