That and we reaching the point where computers and radios that contain
or are married to them are over 10 years old (some a whole lot older,
think Pioneer).

I'm halfway willing to officially sanction
all discussion of antique radios
;)
That half might get you punched in the nose.
Actually, there are no good antique radio groups/lists - all are watered
down. There is a good military radio list, however.

My Racal RA-1792 receiver is completely computer controlled and that was
designed nearly 20 yrs ago, although mine was only made in 1989.
My radio is fitted with the remote control board and the plan is to write
a program to control it over the network (using an appropriate age computer,
of course) and stream the audio over the network too. Then I'll be able
to play radio (almost) anywhere in the house...

.. a couple of years ago a friend asked me to repair two Sherwood "Micro CPU
100" Stereo FM tuners from ~1974-76 which had an embedded RCA 1802 microprocessor.
This was a high-end consumer product in it's time.
While the construction was atrocious (high-end consumer construction,
still in the low end of the spectrum of electronics construction) they were
interesting (and 'collectable' / 'significant') as they would have been
one
of the first consumer products to use an embedded microprocessor in something
other than a 'computing product' (i.e. not a computer or calculator).
Actually it might be nice to build a list of such 70's era products that
(non-obviously) contain embedded microprocessors.

That's a closely guarded secret. The chip collectors like to buy up such
items and strip them for the collectable ICs.

Perhaps I'd better not mention that a certain Fluke data logger contains
a 4040 + support devices for the main control processor and a second 4040
+ similar devices on the paper tape interface card...

There was a TNS1000 microcontroller that had been masked-programmed to
play 1 of about 20 different tunes. In the mid 1970s there was a rash of
doorbells using that chip, both as commercial items and as magazine
projects. At least one of the latter was called the 'Microchime' from
what I remmeber.
