Could that not be reverse-engineered from the boot code in e.g. Emulex
UC17 ROMs? They could do TMSCP...

BTW what PROM blower would folks recommend for creating/imaging M9312 ROMs?

Possibly, but some (me) are sticklers for original code. Plus, I am not sure, 
but I think someone said this rom did something really bizarre to fit in the 
available rom space - self modifying code or something...

Data I/O 29B

No way the M9312 can self modify, it is a burn once PROM - 82S137/Am27S32/74S573 (1024x4-TS) and can easily be read and blown on a Data I/O 29B.

If you have a good copy of the original code it WILL replicate on a new PROM just fine.
