Re: [1st] 6100 acting flakey
Get rid of the DOS card if installed, get another pram battery from a different source, maybe a video PDS card, about 10 or 20 bucks and allows the connection of a monitor, you can run 2 if you want, this allows you to check the stock video and be sure the problem is not in there. The machine will also runs faster off the video card. If it has enough RAM 40 or so, take it out and reseat it. Also the small reset switch on the back of the machine, try starting it, then push that in tiny switch and hold it for 15 seconds or so. It may restart or you may have to restart by the regular means. Don't forget the pram reset, I would let it chime 3 times I missed or blinked and did not see how much RAM you have on board. If it is 8 megs thats the built in RAM. You will need some more at least 40 to run 8.6 which is where my trusty 61 likes to hang out at. When I bought 40 megs of RAM when this machine was new, it was $1,300.00 for 40 megs. Ya I have mine up to 256 but would not go that high until I have done the above and you know you have a working machine . I am betting the DOS card if it' installed. If it gets running, Newer made some good accelerators, I have one that gets going at 300 mhz, still does a lot of work and the software is dirt cheap but still does what it did when it was the main mean machine. You just take a little time to contemplate Mine runs 15 hours a day 7 days a week, I have gone through 3 pram batteries upgraded the HD. PCI is really the way to go, although PDS was a better technology. But PCI is what was built and if your looking to get a good performer the PCI gives you more choices. A dollar for my 6100 never...It will still be running when ants rule the world. I am sure I missed something but will pull out more info.

Re: [1st] 6100 acting flakey
It probably is a heat problem - it definately lasts longer with the DOS card removed. I've got a small fan that I might mount in there to increase the airflow a bit.

Re: [1st] 6100 acting flakey
I have a G3 upgrade card in my 6100, which with the card being vertical and the heatsync being some strange shape and size, it is difficult to mount the fan on the heatsync itself. So, I got one of those PCI-slot fans, popped the metal bracket off and stuck it out the right-angle slot. It seems to keep everything nice and cool, especially since the hot G3 processor is on the opposite side of the system fan in the power supply. Yes, Arctic Silver may be expensive, but in my experience it really does have superior heat conductive properties. I bought a 12 gram tube (way too much) for about $20 at Fry's, which will probably cover every processor I have (and I have at least 20 macs, and 10 PCs) at least three or four times. The stuff goes a long way. A 3.5 gram tube is like $8. -- 1st-PowerMacs is sponsored by http://lowendmac.com/ and...

Can't imagine much air flows under or over the expantion cards in the corner probably just sits there spinning around if anything. You can prop up the 6100 case on bottle caps to give it an extra 1/2 inch or so which will allow better airflow out the bottom. I used cat litter caps. You could use prescription medication caps, a small block of wood or plastic -- anything to raise the case. A second thought for cooling is to find one of those clock chipper fans that press fit into the heat sink. I think they are a standard 40 mm fan thin enough to press into the heat sink. I have one but can't find it to give an exact measurements. Any good electronic supplier should have one for a few dollars. Just raising the case gives my 6100 with a 300 MHz G3 with an AV card bracket (similar to the DOS card bracket) sufficient cooling in the summer when room temps exceed 90 F. However, since your 6100 still overheats without the DOS card perhaps the heat sink grease has dried out as mentioned in an earlier post by Jeff. In that case following Jeff's suggestions to fix that problem would be a good start. Good luck -- glen. -- 1st-PowerMacs is sponsored by http://lowendmac.com/ and...

Re: [1st] 6100 acting flakey
Date: Thu, 17 Nov 2005 10:50:06 +1300 From: Richard Halkyard [EMAIL PROTECTED] I've recently acquired a PowerMac 6100 with the DOS card installed, and it seems to be acting up. It has a fresh PRAM battery, but will sometimes act as if there is no battery (startup chime but no display), and then act fine with no data loss later. When it is running, it will occasionally lock up, with coloured pixels randomly flashing in the top-left of the display. I've tried swapping and removing all the bits and pieces - DOS card, cache, RAM, hard disk, CD and everything. Its driving me nuts, because I rather liked the idea of having an (old) PC and Mac in one. Any ideas? I've seen similar symptoms in several 7100s and the cause is overheating of the CPU chip. In those cases, the CPU chip was overheating because the heat sink grease had dried out and was no longer doing its job. It's not a certain diagnoses for you, but it's fairly easy to test and will only cost you $2 - $3 and a trip to Radio Shack if you don't already have some heat sink grease on hand. Remove the motherboard from the machine. Carefully unclip the heat sink (push the tabs out from the back of the board). I write, carefully, because putting undue downward pressure on the heat sink has been known to *crack* the CPU in several cases. There will be a white residue on the CPU and on the heat sink. Originally this stuff should have been nice and creamy. At this point it is probably dry and powdery. Gently clean it off using rubbing alcohol (70% isopropyl) or 90% isopropyl and some kind of swab. In a pinch Q-tips or cotton balls are okay if you're careful not to leave little polyester fibers everywhere. Clean it off of both surfaces. Let them dry. Heat Sink grease is available from Radio Shack for $2 - $3. It comes in a little blue and white tube on a card which is usually hanging on a peg board. Sure, you can spend $15 on Arctic Silver, but the RS stuff does the job well enough. Apple a little dab on the square metal die in the center of CPU. Do not overapply. Heat Sink grease is mildly electrically conductive and if it runs off of the chip onto the pins of the CPU it can cause shorts. I killed a Power120 that way once. The grease just needs to fill the tiny spaces caused by the CPU die and the heat sink not being perfectly flat surfaces. Carefully clip the heat sink back into place. Try not to slide it from side to side when installing it. Shoot for a straight approach to the CPU without a lot of side to side sliding. Coming in with the heat sink angled a bit, so that two clips go into their holes before rotating the heat sink down so that the other two clips hit their holes often works well. Resinstall your motherboard and test it out. You may also wish to consider installing a little fan on the heat sink. The fans typically bolted to 80486 heat sinks could be unscrewed and fit nicely in the center of the x100 heat sink. Use small cable ties (also available at Radio Shack) to secure the fan to the heat sink tentacles through the fan's screw holes--i.e. the cable ties go through the fan's screw holes and around one of the arms of the heat sink. You can suspend the fan just above the flat heat sink surface this way. Date: Wed, 16 Nov 2005 22:00:52 -0800 From: Matthew S. Carpenter [EMAIL PROTECTED] I tried to grab it but still ended up dropping it about a foot... Anyway when I brought it to the lab upstairs I couldn't get the damn thing to glitch out...Gad, it made me look like an ass. Probably jolted the heat sink about just enough to make better contact with the CPU. Perhaps rubbed some of the powder into a better position.

I never had any extra cards in my 6100 I imagine the addition of a 486 card or whatever the DOS card is probably makes it even hotter. It's really kind of sad the 6100 had to get such a poor design as far as cooling is concerned. I swear, I'm not going to post anymore on this issue unless requested.
