some time ago I made some attempts to build a homebrew Senior PROM. I
got to the point of being able to boot a program and (by generating an
NMI) enter the Senior PROM utilities and even save RAM to disk. But I
wasn't able to generate a 'resurrect' disk (i.e. a standalone bootable
copy of a running program) since that needed the Senior PROM utility
disk which didn't seem to exist (specifically, I could find copies of
utility disks for version 1 & 2 of the SP, and an EPROM from version
3.01, but not EPROMs from version 1 or 2, nor a disk for version
3.01).
Mike Maginnis just passed on a copy of a senior prom utility disk for
version 3.0 which (from the similarity in the version numbers) I
believe has a good chance of working with the 3.01 roms.
Unfortunately I don't currently have access to a system to test this
out in, so I'm posting some links here in the hope someone else may
way
the 3.01 eprom (in a form suitable for burning to a 27256 for a
platinum iie ) is at http://www.jamtronix.com/senior_prom/senior_prom_301_combined.bin
the 3.0 disk image is at http://www.jamtronix.com/senior_prom/sp30.zip
a longer version of what I've done so far (and a bit more context on
the Senior prom etc) is at
