M9301-YB Bootstrap/Terminator ROM dumps / listings?

[Josh Dersch]

The 11/34 seems to be pretty healthy, I've punched in some code to do 
some basic testing and the CPU seems to be capable of running simple 
programs and the RAM seems capable of holding data.  So that's good.  
I've also verified that the console SLU is at the right address and 
vector (it wasn't initially, due to a pair of bad DIP switch blocks), 
and I can read/write characters from/to it. Huzzah.

The bootstrap ROM doesn't seem to be executing properly, however. After 
power-on or a BOOT/CTRL It'll run for a fraction of a second and then 
halt, leaving me at address 0 with 161721 displayed.  ROM Data appears 
at the expected addresses (773000-773777, 765000-765777) but I don't 
know if it's at all correct.

I need to scare up a second SLU so I can get an emulated TU-58 hooked up 
to try booting XXDP, but in the meantime I thought I'd see if I could 
verify the ROM contents manually (it's only 512 bytes long).  I can't 
find a listing, however -- the operator / maintenance manual doesn't 
contain it and I haven't found it anywhere else.  I've found a reference 
to a microfiche, "EP-M9301-RL-A" that supposedly contains these 
listings, but it doesn't appear to be archived anywhere.  Anyone have 
this, or have dumps of the M9301-YB PROMs?

Thanks,
Josh
