HP8568B firware eproms anyone ?
My HP8568B has started to do weird things, and as far as I can find
out, the A15U37 Eprom is hosed.
According to the label, the HP partno for the contents is 85660-80080
The chip has a HP partno of 1818-3329 but looks like a regular
AMD27256 Eprom to me.
Anybody out there with a 8568B who are also able to email me the
contents of the four eproms on A15 ?
I'm not sure if the firmware of the 8566B is different from the 8568B,
anyone know ?
I think this is the second report of eprom failures I recall on the
list, should we start to make a EEPROM library for futures sake ?

I'm pretty sure that the '66 firmware is different than the '68, or I'd
offer to copy mine for you.

That's not a bad idea, though it does unfortunately raise copyright
concerns...

I would expect so, but on the other hand wouldn't be surprised if they
were the same.

Not as long as the firmware is used only in original HP equipment.

There is such a library maintained by Bruce Lane at Bluefeather
Technologies. He only archives firmware of instruments no longer
supported (off support), and I believe he has at least some level of
permission from the test gear companies.
You might try the hp_agilent_equipment list at yahoo - this has
quite an active group of people on it who have 8566/8568s and a couple
who I think may have the firmware you want already available as a file.
Of course *I* am looking for Austron 2200A firmware for the same
reason...

I would tend to agree on the copyright concerns. I'm retired from HP/Agilent,
and happen to know the guys that do the support on them, so I just forwarded
these messages to one of them. Perhaps we can get a solid "OK", or at least one
with such strings attached!

I work for Agilent. In my lab I have both an 8568B and an
8566B. How would I read out the contents of the eproms?
I don't know much about eproms.
I looked up that part number; it is an AMD27C256-200DC.
There are a bunch of reliability reports on it, so that
sort of confirms that yours may likely have failed.

Any EPROM programmer should be able to read it out. I usually store it in
HEX (aka Intel HEX format) and BIN (aka Binary) formats. While you are at it,
I would backup all the EPROMs. Maybe we could have Agilent put them up on
their web for support services.
Cheers,
Magnus

Hi Rick,
I'll try the ones at the bluefeather archive first, if that fails
I may get back to you.

John Miles (jmiles@pop.net) on hp_agilent_equipment (yahoo) has a lot of
experience with the 8568 and 8566 analyzers and is probably your best
opportunity to find what you need. I know he had an 8568 which he sold,
but not before copying the EPROMs.
