System 7 seemed somehow "tuned" to run really well on the IIci. Click to expand... Yep, it is the first Mac with the new universal ROM that has 32-bit QuickDraw, Gestalt, and m…

I booted your IIfx from an external hard drive without a terminator at all Tempest. I think it depends a little on your drive too. Terminators are tricky and unpredictable as to …

I just vacuumed the psu fan without even opening it and the case fan while I was at it, and the G4 is now quieter than it has ever been!

I received a reply from Otherworld Computing (on a Saturday, no less!). I'm posting it in its entirety for future reference... PowerPC 750FX and 750GX upgrades support a fea…

sounds like the fan, so yea try blowing it out, and worst case you can replace the fan fairly easily

Today, my Mystic G4's power supply started making an out-of-the-ordinary noise instead of the typical. With the unusual noise, the case slightly vibrates as well. I could tell it w…

This site seems to be selling a new battery with a case and contacts compatible with the Macintosh Portable. Click to expand... Upon further investigation, that company wants y…

Can you give some links of the 6v lead acid battery I should buy and exact specs?I understand nothing regarding electonics and electricity! Click to expand... I've come up with…

I love my Ataris, but they have been put away for most of the past year while I have been slowly moving my music setup around. I've got a box of Dr. T's software which is all amazi…

Yes, after a little trial and error, I had mine at full speed for both OS 9 and OSX. If OWC doesn't solve the problem, I'll get my machine out of storage later this week and check…

Regarding the dead PMG4: The reason it isn't responding, powering up or waking from sleep is due to the Power Management Unit getting a bit screwed up. To fix the problem, I woul…

if I look off the network settings for the G5 Tower that auto-connects, is there a way i could manually enter that info in on the G4 MDD? Click to expand... If I recall, in aut…

Yeah, I wouldn't doubt. I think that was the initial reason it was disconnected in the first place, I guess I just "happened" to revive it for a few months. And I've had an AWEFUL …

If you enable dynamic power management, doesn't that mean the CPU drops to half-speed when possible, as in idling while you look at a CPU speed screen? CPUD and other speed sensing…

Okay I emailed OWC's tech support. In the meantime... Metronome indicates that my bus speed is indeed set to 100MHz. I double checked my jumpers and they are correct for that sett…

The power supplies on that model are known to fail, so that may be what died. As for ethernet, sometimes the computer won't autonegotiate a suitable connection with the central hub…

I have a PowerLogix 1.1 ghz processor that's in a B&W G3. It ignored the motherboard jumper settings as far as processor speed went. I never did try changing the bus speed …

yea it should not be hard to add the termination, but resistors alone do nothing for noise, you need a rc network by the time you figure out what noise is present and do the math …

Hmm, for some reason I'm getting no quote button at the bottom of messages. Anyway, if you're getting 650 MHz when set to a 11:1 ration, then the bus speed of your B&W mus…

I haven't looked at the specs, but it's probably not a big deal to change out the internal terminator packs with the "proper value" of resistor to create an on-board Black Terminat…

Do you use two (3.1V) or three (4.65V) to replace a 3.6V PRAM battery? Or are you referring to replacing the 4.5V square PRAM batteries as pictured above?

You can try contacting support at Powerlogix or OWC.

Yes I desperately need one for my IIfx. I'll send you a PM. Tempest

No dice. I moved the number one jumper to the number four position as shown here to no effect. Apple System Profiler and Metronome still report 650 MHz. TattleTech, interestingly, …
