Yes the machine sounds as if it is healthy, even the display is present. The boot up will hang if it cannot read back from the display – so it would not beep. I would guess the contrast line has insufficient swing.

I even make a program: 10 beep 20 goto 10 run and it beeps over and over until I break. Since I am able to do this, wouldn't this mean that my RAM is OK? Thanks, Chad <snip>
