Hi all,
I recently got a couple early Model 4's with white CRTs and Model III video boards. I tried connecting both monitors to the one machine that has a PSU (second machine is missing the PSU and I'll need to get one - any ideas?).
With the drive open and a disk inserted I can see the "diskette?" text on the screen, but its barely recognizable and mainly looks like a bright streak across the entire display, as if the raster collapsed to one character tall. I thought maybe this was the flyback, but if that was the case, it would just be a single scan line across the center of the screen.
One other symptom is that the floppy drive makes no sound, but the light does come on. I have not yet replaced the filter RIFAs, all of which are wrecked, but I understand the machine should still operate w/o them. Any help would be much appreciated!
