If you are interested in benchmarking with your cache disabled, I wrote a tool to help you disable the cache. Disabling the cache should make a big difference on Dhrystone results.

I sold my Macintosh IIfx to a cool dude about two years back. It was missing a rubber foot or two. I told him that I thought I had seen one around and that I would send it to him, but I didn't find that foot until last month. He was happy to finally receive it. I also asked him to run Dhrystone...

Howdy comrades, I was asked to build Dhrystone for 68k Macintosh, just for fun. I felt I should share it with you all. This ancient benchmark will measure the integer performance of your Macintosh. Let us compare results, if feel so moved. Dhrystone for 68k Macintosh Results: Macintosh SE/30...

Thank you very much. The MacTCP Developer Kit is exactly what I needed. It even contained the document entitled "MacTCP Programmer's Guide", referred to by Falkenburg, which I couldn't find on the Internet. Thank you comrade!

I'm looking to make some Internet applications for System 6. I'm having trouble figuring out where the MacTCP API is documented. I'd like to use MacTCP because it should allow my application to work with System 6 through 9 (with Open Transport being backwards compatible with the MacTCP API). I...

That's a very pretty machine you have there. It's rare to find one in such nice condition. I picked one up new back in 2003, but it broke. It came with annoying stuck pixels. I've had to send it into Apple for various reasons. About a year ago, the hinges made a funny noise when exercised and...

Be sure to replace those old and prone to leaking caps. Max out the RAM, too. She's a beautiful machine.

I replaced all capacitors on the Portable, including the through-hole ones. The Macintosh Portable through-holes are plated through-holes. This means that solder is supposed to go down through the hole along the sides of the lead. It is easy for me to see that I had proper fill (at least 75%)...

I had two dead Portable batteries. I wanted to re-cell them, so I attempted opening one with a screwdriver, but that totally messed up and and bent the plastic. I have one remaining, but I don't know how to open it cleanly in order to install new cells. I'd appreciate any advice you could give...

If you installed any backwards, that is exactly the problem. You have a lot of Portables. What do you do with them all? Do they all have batteries that work?

It is great to know that the PowerBook 100 adapter is good for charging as well as running without the battery. It is also good to verify that it is a switching type. There doesn't seem to be any special rigging required in order to run off of a 9V supply. I was able to boot into a sad mac with...

Yes, trag's caps are great. I need to get some more from him. I am missing one capacitor in order to complete the replacement on my SE/30. I am also missing one capacitor in order to complete the replacement on my LC III. I was hoping to finish the SE/30 this weekend, but it looks like I'll have...

When the computer first boots up, it displays a funky pattern on the screen. This pattern goes away in less than a second. This is probably a typical memory check or something. In attempting to photograph that, I discovered that some other sad mac codes are displayed before the final code is...

I finished capacitor replacement a few nights ago. Here are some pictures.

After I finished replacing the capacitors in this guy, I assembled it with the second floppy drive in place, connected with a self-made ribbon cable. The drives stack very well and are firmly in place. The upper drive could slide around if I forced it hard enough, but it is held in place with...

I finally got my tools in order and took the time to do some work on this smoking hot babe today. First off, I removed all the nasty caps with my new diagonal cutters. Some of them very easily came off from the PCB all on their own. Others I tugged at a little bit. Some left leads behind that I...

I suspect that most of the solder is directly under the capacitor: the rest has been mostly corroded away. I do see some solder on the outside, but I can't tell if it liquefies when I apply the iron. I don't think it is liquefying when I do apply the iron. This is less a problem with HighK...

The Macintosh Portable web server is interesting. I won't be doing that, though. I am currently attempting to remove capacitors from my Portable's logic board. I used some flux to clear away most of the corrosion on the capacitor leads. There isn't much solder left. I took my soldering iron to...

For those who don't read Japanese, the procedure is pretty simple. I had taken off the floppy drive cover, but I didn't need to. I just needed to unscrew it so that I could fit it into the hard drive bracket with the floppy drive cover on (without the screw heads getting in the way). You just...

Holy crap I found some more pictures. http://square.umin.ac.jp/~itoh/dual_fdd_2.html This guy is seriously awesome.
