Hi!

A "super cap" may not last long in 1985 circuitry.

Dunno. I've got a Fisher tuner based on a Toshiba chipset (a 4-bit
microcontroller with integrated memory and a separate display driver)
that uses a supercap to keep the memory running.

Does is seem pretty common for those older supercaps to leak what looks
like machine oil?
