Q: I have an old Centris 650, OS 7, with SuperMac CRT monitor. I've got vertical stripes covering the bottom half of my monitor screen. Anyone know this problem?

Moved one of those monitors just yesterday! SuperMac was know for large monitors that ran off NuBus cards. I would start by removing the card and reseating it a couple of times. You may have a bad connection. Otherwise, some component may have failed and it is improperly scanning the bottom of the screen.
While you still have the top half, go into the monitors settings and identify the screen resolutions that are available and/or in use. If the monitor dies, you will have to zap the PRAM to reset the monitor settings to a new monitor, unless you have an exact match with which to replace the old one.
Name a large city near you and maybe we can identify a mac user group in your area. I helpped a client move several hundred large monitors a few years back. I do not know if he still has the monitors but there were several SuperMacs in the collection.
Good luck,
