[rescue] Need AT&T 3B2/300 EPROM images to replace ones missing in my system

I have started working on restoring a 3B2/300, and right away I've discovered
the probable cause for the machine's catatonic state. Three of the system
board EPROMs are missing.
Anybody got a /300 they can dump the EPROMs on? For some reason the AATKL ROM
(3/4) is still fitted, so technically speaking I only need images of the AATKJ
(1/4), AATKK (2/4), and AATKM (4/4) EPROMs.
I am also after a copy of the AARAM (2/2) ROM from the NI (ethernet) board. My
EPROM programmer can't get a good connection on pin 1 of that device and reads
it as all zeros. I'm pretty sure this is the reason the board isn't detected
properly (in my /400).
until further notice
