Hi Dave,
That is an issue that needs to be re-emphasized. You can't read
the EPROMS in a 7L18 without using multiple rail supplies. +5V

frame
There is also a tekscop...@yahoogroups.com which is a LOT more tolerant of
random questions.

teksco...@yahoogroups.com is the one to go for.
Someone has also started a Microwave equipment group too.

Hello all,
I have an old 7L18 spectrum analyzer that used to serve me well on the
higher bands.
Unfortunately, the controls have got into complete disorder.
It seems like one or both of the ROM's are dead.
Anyone have / knows where to find ROM images of the 7L18?
Thanks,
Adrian
