Hello,

my Tektronix 496 Spectrumanalyzer suddenly doesn't make any digitally work,
some key-LED's light and a very slow analog sweep can be seen on the screen.
After looking at the servicmanual and testing the 6800-prozessor good i have
start the internal self-test by setting the DIP-Switch S1033 on the
Memory-Board. After Power-On and waiting for a few seconds the ROM-LED
DS1038 on the Prozessor-Board blinks 16 times, which means that the PROM
U2023 (160-0838-00, Mostek MK36xxx, 8kByte, same as in 492/492P SN B030000
& UP) on the Memory Board has tested bad.

Because i'm equipped with an eprom-programmer, it is possible for me to
program an new eprom myself - i only need the ROM-Image (8K) for the
defective ROM-Device U2023 (160-0838-00)!

I've asked the tektronix support, but they don't have any ROM Image for the
49x-Analyzers.


Do any have a 8 kB ROM Image for the TEK 496 / 492 or do know where i can
get it?
