Are images of UCSD-P for the Pascal Microengine available somewhere ?
That would be version III of the UCSD-P system.

Hans Otten had unpacked text/code files supposedly for the Microengine
on his
pascal.hansotten.com web page, but this seems to be under reorganization
currently.
I could look at home where this is on my disks. It is not a bootable
image, though.
I am also looking for such images, as well as the boot prom listing/dump
(not the MICROM
contents - well, could be fun as well) beyond the stuff that can found
on bitsavers.

What boot PROM? Unless yours is different than mine, It has no boot
PROM, nor a place to install one if you wanted to.

Looks as if there are several incarnations of "the Pascal Microengine",
or rather, a boot prom is likely on the winchester controller, not the
floppy-only main board.
The WD9693_PasIII_OSref_Jul82.pdf describes a boot PROM at
0xfe00-0xffff, namely when talking about "SB1600 PROM" and "ME1600
PROM"
on pages H-1/H2.
In absence of such a PROM, it's apparently the microcode that issues the
few commands to setup DMAC/FDC for autoloading.
