I just got a 1984 Macintosh 512K yesterday, and will be documenting the adventures with it here. Here are the first pics I took before anything was done: As you can see from the serial, this Mac started life out as a 128K. Pretty cool. It’s the best of both worlds in my opinion. The awesome...

Some GREAT news! I sprayed the sensor on the 400K drive with alcohol, scrubbed it with a toothbrush and it works! No more clicking and it boots from the drive now! So now I don’t have to buy another drive. Awesome!  8)

Thank you! I’ll definitely check out DogCow’s blog. A quick little update on the 512: it works fine, but the internal 400k drive doesn’t, unfortunately. It has the “click of death” and the optical sensor doesn’t appear to be the problem (stepper still turns with it unplugged).  So I think I’m...

It has arrived!!!! I can’t believe it. I have wanted one of these for ages. How could it possibly be any cooler?     It’s a 128K that’s been upgraded! Presumably by Apple, as the badges have been changed out too, which is not something an individual would have likely went through the...

Just got this in. Good old M0130 400k drive, made in 1985!    Was sold as parts because it “does not accept a disk,” and boy were they right! The entire mechanism was ceased, worse than I have ever seen on any other drive, but it’s working great now after about an hour of work. Makes the...

There is a 1986 and a 1988 revision. I own both, but don’t remember the notches. I’m assuming it’s the 1986 revision that has them on only one side and the 1988 revision that has them on both sides. I’d have to look at them again.

Yeah, you could fairly easily upgrade it if you really wanted to. Would probably be easiest to just find a motherboard from an FDHD/SuperDrive. I actually quite like the 800K units though, as they can still work with the old 400K external drives and I believe they also are compatible with the...

Yes, the Mac serial number decoder incorrectly reports any M5011 as an FDHD. My older M5011 literally says on the back label “1MB RAM 800K Drive 20SC Hard Disk,” yet the serial number decoder shows it as an FDHD. Another issue is, the FDHD wasn’t released until 1989! So a 1988 FDHD is...

Are you sure about that? It may be that you have a late-model SE that uses the newer “copyright 1988” label instead of the “copyright 1986” one. I have one myself. Also, there is one very wrong piece of information that I see online quite a lot; it’s that the M5011 is automatically an FDHD...

It must have been used very little if it has no burn-in, as most compact Macs have at least some by now. I think all of mine have it to a certain extent.

Nice! Those aren’t bad machines to start out with. :)  That SE looks almost new with very little (if any) yellowing. That Plus used to be a 128K or a 512K, and it has had the Mac Plus upgrade kit installed. Pretty cool, because it still looks like a 128K/512K from the front. That’s the only...

This is cool! While I don’t personally need a new SE board, this is an awesome project, and I’m sure plenty of people could use this for repairing bombed SEs. I’m a huge fan of the SE. It’s one of my all-time favorite Macs.

It’s what a lot of hard drive manufacturers used for PCB insulation, so I guess it’s fairly effective (when it’s not rotten).

Not entirely. There are several areas where the circuit board can make contact with with drive body. That foam is there for a reason.    I remember on the first replacement I got for a CP-3041 IDE drive, I installed it (with no insulation), sparked and fried instantly. Second one, used some...

Very cool. That bracket is a beast!

Can’t answer your question about the CPU, but good grief! That’s an amazing find there. I’m assuming it can be upgraded to 4MB also?

Yes, the older tray-load models have a fan. Why is that a bad thing? I think it makes them more reliable, as I seem to see more dead slot-load model than the tray-load ones. I’d say they are a little bit easier to service than the slot-loaders also.  I love the tray-load models personally. My...

I think those fail for the same reasons the PC on the IDE versions of these drives do. One of the machines I am very fond of is the Compaq SLT/286, which uses the IDE version of this drive. The reason the PCB fails in the IDE versions is the foam insulation between the PCB and the drive frame...

Also, here’s an inside-shot of the SE with the Rodime installed: You can always identify a Rodime from the bottom. The big, silver stepper-motor is always the giveaway.    Now to find an analog board with the old squirrel-cage/cross-flow fan and this’ll be done (just the fan itself would...

@Franklinstein ah, ok. Can’t wait to see how that turns out when you get the chance to mess with it!    Yeah, I knew the Rodimes weren’t know for good reliability. I too think it’s pretty cool that they were Scottish. You don’t see a lot of computer-related tech from there it seems. They did...
