Thanks, Lyle!
I am looking for a set of boot proms that would enable me to boot from the
RL01 that is connected to my PDP8/A
I've uploaded the two bootroms you need to boot a RL01 on a PDP-8A using a
KM8 (M8317). You'll need to burn the images into 82s126 chips.
I've also
uploaded the corresponding level 8A schmatics/manuals which have this level
of ROM described (IIRC on the third page of the KM8 portion of the
schematics).
I did a little digging - it appears that the MMI 6300-1 is pin
compatible with the 82s126 (and is open-collector as well). I know I
have a few 6309s lying around because we used a pair of them for boot
ROMs for the first model of COMBOARD. I don't know if I have any
82S126s or 6300-1s, though.
You can pick up the images and manual...
Thanks much for providing those.
