Sorry about that. That will teach me to rely on what I call my memory! It has been a long time since I touched the old gal, but i just dug it out to check.
Shift-Fn-Ctrl-Power is the reset combo, apparently. I DO remember having to reset the machine occasionally, however, and that my backup battery was definitely dead. I seem to recall I used to have to reset it with the power plugged in, too, which is not supposed to be the case but I believe was for me. Maybe it had to do with those dead coin cells.
Anyway, among the Apple machines I have used professionally over the past thirty years, the Wallstreet was a particular favourite. I especially liked the keyboard, which for me was superior to even the Pismo’s. I probably wrote 300,000 words on a Wallstreet.
A refurb of my machine is on my “to do” list now that I have retired; I have a rebuilt backup battery ready to go, and a recapped charge board, which is a common point of failure. All I need is to get through all the other things I need to do first…!
