Hi,
I'm working on a mis-behaving HP 8904A and am trying to find the latest
firmware to burn into an EEPROM.
The HP p/n is 08904-87011 - the rev should be 00790A or later. Its U12 on
the main CPU board (A2) in the unit. The chip is a TC57000AD-150 (1MBx8),
which I can't read to check (my eeprom reader can't handle it), but I could
get a third party company to (re)program & check. I have the service manual
from the Agilent web site.
This unit is now long discontinued by HP, so no luck from them - If anyone
knows where I could get a copy of the firmware (at a realistic price - this
is a hobby!), I would be very grateful.
Thanks
Mike
