Re: [volt-nuts] "*WAY* too expensive for even Keysight to redesign"
Aside, there are private fabrication houses that make short runs of
obsolete chips in order to keep mission critical electronics running,
such as in aerospace and military applications. I'm not sure what
Keysight would actually do, but I would presume not only do they
stockpile key parts, both active and passives, as well as full boards
for board level swaps, but periodic re-checking their inventory for
functional integrity can be a never ending task as components age
beyond their expected operational life. If parts truly were to
become obsolete even beyond private fabrication, their management
should design replacements boards and field test them way in advance
of parts becoming extinct, until they decided the product was not
worth maintaining.
From the site you linked: "Our life cycle management program assures
you of a dependable, quality source of obsolete IC's forever. "
Now it was my turn of having a good laugh.. thanks for that, I didn´t
knew that this service existed.

No mention that the price may go up exponentially each time you ask for a
quote, and don't try to buy two dozens. They probably won't make a run for
much less than several thousand pieces, and there will be steep lot
charges in addition to a very high unit price.
Been there, done that...

Oh they'll do a few dozen, you'll just pay for a whole wafer...
...each time ;-)

Ehh, dudes... a m68k compatible chip is not unobtanium.
Besides, the HP3458A is written mostly in K&R style C, using
IEEE floating point so porting it to another chip is not a big deal.

And now that you mention it, there are FPGA/ASIC 68K cores as well.

And now we returned to an emulated version of the original core, as my
joke predicted.... :D

Yes, these folks do not market like the commercial side but there is a small industry supplying obsolete parts. They are not usually not focused to sell to the public. Sometimes, they just hunt around for NOS stored in some forgotten warehouse, then they test components to insure like new functionality.

As others have suggested, it likely will not be not cheap, so the cost to maintain old devices with obsolescent parts over the total cost of a redesign has to be a strong consideration.

Sorry folks, sent too fast. Errors corrected.
