Rumor has it that George L. Rachor Jr. may have mentioned these words:
Just inherited a Model 4 with twin floppies.
The CRT seems to powerup but no text on screen..
The lower drive light comes on but no other activity.
Is there a common failure mode for these critters?
The foremost 'failure mode' is no boot floppy! ;-)
Try holding the break key and press the reset button (the inset red button
near the numeric keypad) and see if it comes up to the Model III cassette
basic. You should see a memory prompt, like "? MEM Size" or somesuch --
warning: It's been almost 20 years since I've diddled with a Mod4, so the
neurons don't fire quite as well as they used to... ;-)
HTH,
Roger "Merch" Merchberger
