Thanks Kent. Yes - it's the 6 screws on the bottom and the screws that
hold the handles to the back. Then there's 6 screws in the metal bottom
that hold down the keyboard assembly.
Found something interesting - and badly designed - when I got in there.
There's a circuit board that hold the keyboard scanning chips. It hangs
upside-down from the metal from of the Pratt-Reed keyboard assembly.
It was held on in four places with ... glue! Which, of course, after
30+ years, had lost its grip, leaving the board dangling by its wires :(
A trip to the hardware store for some 5-minute epoxy, and it should be
good for another 30 years!
David
