- A hearty thanks to all who participated here. I have edited it down to the
- relevant points. Hope this answers some of your questions, too.

- Help !!! Where can i find a Screen saver program for the c-64, to kill the
- monitor after 5 or 10 minutes of non-use. (To prevent screen burn-out) Thanx

- Screen Saver is a program seen mostly in MS-DOS machines. It automatically
- blanks the screen after a preset period of time to keep images from being
- burned into it. Courtney

- Shouldn't be hard to do, though. I haven't seen one for the 64, but to avoid
- discrepancies with video hardware, the one I use at work just sets colors to
- black on black. A little ML routine in the ever-popular cassette buffer
- should do it.

- Well, your C-64 shouldn't ever NEED a screen saving type of program, its
- not using the same kind of technology that MSDOS and RGB monitors do.
-
- Tell us why you think you need it, OK? There is a direct VIC II chip
- register which will blank the screen, but if something HAPPENS to your
- software/system, you'll never know what happened.

- I've left my computer on for *hours* with the same screen...didn't cause any
- problems at all.

- Sure you need a screen-saver, if you leave your monitor on with one program
- all the time. Even the old Atari 2600s used to char up TV sets when they
- first came out... now all the game programs change the title screens around
- so they don't take a set. Most people don't leave their 64 on all day,
- every day, so it hasn't been a problem. My 128 monitor has the BTP-128
- status line starting to burn in, though.

- I've seen a screen saver for the 128. It's public domain. Haven't seen one
- for the C64 though.

- I'm burning out the monitor to my XT at work by having a main menu
- sitting up 8 hours a day. Finally had to put in a screen saver. Never
- had the problem with the 64 or 128 cause they are usually just turned
- on to play or work with a program, then shut off.

- Well, I'm not a technical type, but someone once explained to me that the
- C64 constantly updated the screen thru the raster and that you never had to
- worry about damaging your screen...

- Beats me, McGee...I only live here!

- EVERY monitor is constantly updated by the raster. This will not help to
- prevent screen burn in as the same pixels are constantly being illuminated by
- each pass of the electron beam. A simple way to solve the problem for those
- who leave the 64 on for extended periods of time with the same screen in
- place (for instance, business users who don't wish to wait for a reload each
- time they go to the computer) is the most obvious -- turn the contrast
- (and/or brightness) controls all the way down. If you can't see it, it
- won't hurt the screen.
- When you're ready to resume work on the computer, simply turn the controls
- back up. Doesn't cost a dime, requires no installation, and works every time.

- Thanx all for the input. Thought it might be nice/needed for a bbs set-up. I
- use one on my ST so figured i needed one for the c-64. Gary

- Gary,
- A BBS is probably one of the touchiest things to ever operate on a C64,
- and if the 'feature' isn't built into the BBS, you're treading on dangerous
- ground to add it. Several BBS's *do* come with a screen off/on toggle, like
- RAVICS and COLOR64, that I know of personally. I just leave the monitor
- turned off on my BBS...saves the screen *and* the power bill. <smile>
-
- I'll move these messages over to category 4 where they might be of
- interest to someone in the future.

- DEB: Turning monitor power off is OK. This will not affect the computer or
- the program in progress when using the 64 The monitor, with the 64, is a
- completely passive device. The 64 doesn't know (or care) whether the monitor
- is on or off. The only problem you
- *might* encounter shows up only if your power up/ power down occurs very
- frequently. This is a rare one but worth noting. Like a light bulb, the
- filament in the CRT must go from cold to very hot each power up. This causes
- mechanical stresses which will eventually cause it to burn out - no crt -
- Very, Very rare prob. Your method should be harmless.

- In the January, 1988 copy of "RUN" magazine, on the almost last page, there
- is a program called "Blank-it 64". It will blank out the screen after three
- minutes. Hit any key and the exact screen reappears. I imagine you could
- change the length of time if you wanted. It works very very well. There
- have been times that I have left my computer non because I had to run out to
- the store while it was printing, or was cooking or the phone rang or
- something that took me away from the screen and it was nice to know that it
- would blank out on it's own if I was away longer than expected. By the way,
- the program in "RUN" is pretty short. In the February issue there is
- supposed to be a program that will blank the screen for the 128.
