Hello people! I recently acquired a Mac Plus while doing a clean out of my grandfather's old factory. The keyboard and mouse were FUBAR, as they had been left under an old can of paint which leaked all over them. He said that there was also a hard drive somewhere, but we couldn't find it. I scrubbed as much old paint of this Mac as I could, and besides from a rather even coat of yellowing, it seems to be in pretty good nick. I took it home and plugged it in, and it made the start up bong and the floppy drive made noises, but the screen never fired up. I cracked open the case and besides some dust, everything seemed to be in relatively good shape. No caps were leaking, and nothing looked corroded. I also discovered that this Mac had 4Mb of RAM. Nice! I came to the realisation that this Mac had deeper problems. I noticed when I found the Mac, that it had LOTS of screen burning, which indicated to me that the CRT as a whole could have just bit the dust, or that the flyback transformer was completely screwed. Further poking around inside the machine also revealed that the CRT power connector looked like it was burned or melted. I thought while I had it open, I'd perform the cap change just in case, for longevity if I ever got this thing working. I couldn't find all the correct caps, so I used some higher volt ones, and there was one blue non-polar one that I didn't change at all. Upon firing this up after the change, it worked! I have no idea why the cap change fixed it, non of the caps seemed damaged in the slightest, I verified this when I removed them. No residue or anything! So now I have a semi working Mac, but I have 2 issues which I'm unsure of how to fix. The computer makes a REALLY REALLY high pitched squealing noise. I think this may be the flyback transformer, but I'm not sure. UPDATE: When I fired up the machine to take the photos in this post, the noise was gone! I'm unsure if it will come back, has anyone else had this problem? It's also VERY hard to insert floppies into the drive. The seem to be stuck on something, I'm not sure what though (I've made sure it's aligned correctly). Also, sometimes when I put them in, the jitter around in my hand like crazy until whatever mechanism in there stops, and I can finally insert the disk! And on top of that, the auto eject doesn't seem to be working, but I'm not that familiar with macs that boot directly from disk, as my other mac (a mac classic) is currently not working AND it has a hard drive. I also have no boot disk to test this machine further. Let me know what you guys think!
I recently picked up a Macintosh SE for $5. The hard disk was dead, as I expected. I put in a boot disk and turned the computer back on. However, I soon realized I was using a System 1.1 Boot disk, which is not compatible with the SE. I don't have an ADB mouse/keyboard, only a 128k/512k/Plus keyboard and mouse. I tried pulling out the disk (I didn't know about the pinhole by the disk drive when I was doing this) , and it came out. I noticed that a small metal bracket is now in the middle of the floppy drive. Is this normal? I noticed it moves upwards when the mac is turned on. I am having someone make a system 6.0.8 boot disk, and I want to know if the disk drive needs to be repaired before I can use the boot disk. If it's just a "cosmetic" problem, I can still use the drive fine by pushing up the metal piece. Thanks in advance
While I'm waiting for parts and money to come in for various motherboard repairs, I decided to fix up a few floppy drives. I took them apart, cleaned them up, applied grease on the sliding parts, and reassembled them. All (six total) but one works fine and boots Norton Emergency Boot Disk on the IIfx. This one drive does not boot. The head goes to track 0 in an attempt to boot, then goes to track 80 and then spits out the disk. I do not know if this disk drive was dead to begin with, I just gathered them and cleaned them up without testing them first. The heads look OK (no broken springs or crooked heads). No broken solder joints from what I can tell The NEBD (Norton Emergency Boot Disk) still works fine on other drives, so nothing magnetic has interfered with the disk and killed or altered it from this drive. When booting from the hard drive and putting a disk into the floppy drive, if says that it can't read the disk and asks if you want to format it. Trying to format another disk also fails. It looks like as if this drive has gone "deaf" to reading floppies. Any ideas on fixing it?
