[Premium-Rx] Racal RA-1795 lost firmware

[antonio]

Hi,
my recently acquired RA-1795 seems to have lost its control program. I can't start BITE self-test, no response from panel controls. All voltages ok according to the manual, even on the processor board.
One of the two UV erasable EPROMs had lost the protective tape on the transparent window, and excessive light might have corrupted the content, even due to storing the set without top cover.
The EPROMs are those located on the processor board, and according to the manual they should host the control program.
Can anybody help me find that firmware?
Thanks,
Antonio I8IOV
