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!

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…

As for the Daystar Diskrunner, I know next to nothing about it. What machine would a Diskrunner be well paired with? I would have thought that, by the time of the IIci, say, it wo…

Daystar DiskRunner caching SCSI card :O so jealous right now. Your haul of SE/30 PDS cards makes me want to :scrambled: xx( Very nice little treasure trove.

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…

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 …

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 posted a number of photos of some of the interesting things on the group's Flickr site.

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 …

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?

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

Gottcha. Well I went to work on it today (finally), and the machine is dead. I always kept the computer in sleep mode while I was logged in and the computer was locked, and apparen…

Tempest, Would you be looking for a black terminator? A couple of days ago, I found my old one (got rid of the IIfx some time ago). John

According to the hard drives article (page 120) in December 1990 MacUser, "the Mac IIfx differs from previous Macs in that it requires so-called black terminators with built-in fil…

It would appear that both power supplies are good, and the 3rd power supply that Tempest sent is good as well. This is the one that tested bad before. I'm thinking that the bad c…
