I was given an old Tandy 3 microcomputer. The button on the right side
of the keyboard says "48K." Was this computer a newer version of the
TRS-80 Model III? I am going to try and restore this computer. Right now
it has a video problem. The screen lights up and has zig-zags on the
screen. Also the contrast and brightness knobs are frozen and move just
a little bit left or right.
