Just a quick update on this. I have a BBS (Synchronet) running enough
that I can dial-in from another PC and connect properly. I started with
the Hayesmodem 300, which was painful, and then changed to the Hayes
Optima 144 which was respectable for dial-up.
I had a number of Optima 144 modems, and they all had severe PCB damage
from leaked surface mount caps--more damage than I had the patience to
try to fix.

I was able to rescue/preserve a Hayes Ultra-96 and Optima-288 by replacing
the surface mount caps. I used conventional electrolytics from my spare
parts box, with strategically bent leads, as I trust these more not to leak
over time. You might consider doing similarly, if you care about your modem.
