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.

Subject: [volt-nuts] 3458A firmware update
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
