Has anyone archived a copy of the rev 9,2 firmware anywhere? I replaced the NVRAM a few months ago and just added Option 001 (about $6 for the four chips) and I'd like to try to upgrade the firmware from the current 7,0. Thanks, Steve WBØDBS

The Agilent site lists the single EPROM REV 9 chip (P/N 03458-88897) for $18.21. The multi-chip (4? or 6?) EPROM REV 9 set (P/N 03458-80023) is listed at $139. Looking at Service Note 3458A-12C, it is not entirely clear to me what 'issues' were resolved by REV 9. Several issues are discussed that were resolved by earlier versions before 8 that were resolved by 8 but I don't see what the benefit would be of 9 over 8.

Forgot to ask, where did you get the chips? SMT or through hole?

Joe, The chips are from Mouser - Alliance Semiconductor 62256, low power, 70 ns through hole as the board was socketed from the factory. I will need to dig through some paperwork for the exact part number. Also need to open the unit to see which version of the upgrade I would need. Agilent's price for the single chip isn't too bad but the multichip price is a bit high, especially if I can burn them myself. Steve On Nov 30, 2011, at 9:48 PM, "J. L.

My impression is that it is a pre-programmed chip (or chips) that you just need to install. Perhaps you could get the single chip, read it, break the file apart, program the 'set', and go from there. Thanks for the info re Mouser.
