   Happy news from the tundra!  According to all the FAQs on the
matter, the bloody batteries are soldered to the main CPU board,
but in the case of my machine the battery was actually socketed!
(I think I must have a very late one.)

   So, we're back to the original question -- "Where can a
TL-5186 be had?"

   Well, for some very low-current apps, soldering-in seems to be the
only way to go, and if there's going to be lots of vibration (e.g.
spacecraft) "hard-wiring" is the norm (save that those apps use welds
and wire-wrap).  But office-environment equipment?  Foo!
