That "8088 Corruption" hack is pretty impressive, indeed! I admire the twisted mind(s) that conceived of, and executed, its development. Given that it evidently uses a VQ-based codec, I'm curious whether Quicktime (say, version 2 or thereabouts) and Cinepak could produce similar results on a...

Mac128 is correct. Although HD and DD media have similar characteristics, they are not "the same media" that have simply been put through more stringent quality checks. There is indeed a difference in coercivity. The difference is not large, but it is not zero.

Although you can often format HD floppies as DD, it's preferable to find some 720K disks from the PC world and use those instead. These disks are the same, media-wise, as 800K Mac floppies. Just format them as Mac disks, and you're good to go. Office supply stores no longer seem to stock 720K...

Running without a fan is possible, but as you will then have the rough equivalent of a Plus, it's not a great idea. I believe JDW did some research on suitable fan replacements. Try searching through the MLA archives to see if his posts have that information. Or perhaps he might be prevailed...

Since the output consists of two stereo channels and one composite video line, there have to be four connections. A standard stereo headphone connector can't work -- it has to have four contacts (tip, ring, sleeve and ground). It's risky randomly sticking connectors into things -- grounding an...

An alternative to 7.1.1 is 7.5.3 (freely available from Apple; no need to download an unauthorized OS release of dodgy ancestry). If the size bothers you, just use Gamba's "digital diet" procedure to make it the equivalent of 7.1.1. You can read the details at...

And no matter what method you use, practice on some junk boards first. Once you've gained some proficiency with your technique, then go to work on your Mac.

And may it work for many, many hours/days/weeks/months/years more! Congratulations on your persistence! And if it should start to misbehave again, now that you know the lay of the land, you'll be able to zero in on the problem in no time.

The "leaking capacitors" problem afflicts many compacts. A standard troubleshooting step for these models is to open up the Mac and carefully inspect the logic board for telltale smudges around the many electrolytic bypass capacitors (and around the battery). My guess is that you will see what...

I'll likely be wiring up my own cabling directly to the appropriate pins on the jack, so that won't be a problem. I just needed to know if the composite output was always active. If not, that would have presented a bit of a chicken-and-egg problem. I'm happy to hear that I don't need the main...

I've just acquired a beat-up firewire clamshell -- the screen is cracked, and the rest of the poor thing looks like it was run over by a truck (for all I know, it was). Other than that, I can hear the startup chime upon power-up, so maybe it has some life left in it. This clamshell has...

It's dead, Jim.

As in trying to acquire any other skill, practice makes perfect. Grab a junk circuit board, and practice removing its caps. You'll quickly learn how much heat is too much, how long is too long, how not to pull on the cap other than very gently, etc. Once you've mastered the technique, go to work...

That's a lot of work (and probably unnecessary). If you haven't already read the lone pdf document at http://68kmla.org/files, you might want to. In particular, check out the section on the "whup-whup-whup" sound, which might be the same as your "flup-flup-flup." Note for future...

Congrats on a job well done! Nice to see another Compact Mac kept out of the landfill.

This problem can be caused by several things. Some of the more common are covered in http://68kmla.org/files/classicmac2.pdf

I'm surprised to hear that alcohol worked -- that's a bit counterintuitive. I've always used WD-40 as a solvent (NOT as a lube here). It works a treat, as the saying goes. Wipe everything clean afterwards, then re-lube gently with chassis grease of choice.

Checking the supply voltage is certainly a good recommendation. You may discover that the voltages are fine, however. If that's what you find, note that a not-uncommon source of the symptoms you describe is magnetic in origin. The magnetic fields emanating from the drive can easily perturb the...

It has now been several years since I last opened up a 400K drive, so my memory is foggy on certain details. But I can say with certainty that two things make direct contact with the floppy media. The head is one (of course), and the other is a piece of felt on a post (?) that pushes on the...

Yes, I fear that your TiBook has developed a problem with the BGA joints under the graphics chip. This problem is unfortunately widespread (the early iBooks were infamously prone to early failure, but other models have suffered from this problem as well). Some folks have used shims to put...
