  1. So I have a macintosh plus 1mb 120vac from 1987 and I have had some problems. so I picked this mac up at savers for $2 back in December and it looked like someone had it in a garage and also had put some bottle with some fluid on it that had leaked into it but had dried. When I turned it on it constantly made the start up sound and would some times respond with the floppy drives, no picture on the screen. The reasons I did not clean it first was to test the before and after affects so that I didn't damage anything in the process, and the other reason was I'm 16 and my dad wanted to only give it to me for Christmas. So a week or 2 later I opened it to see some corrosion but every thing else looked fine. after cleaning the board it would click slowly. So I don't know if it was a good thing or not but I started replacing the caps. I replaced all the caps I could and checked the ones I could not replace with a capacitor reader. After checking every other diode and transistor I switched it on and it started clicking really fast. I suspect that its a flyback after bringing it into my electronics shop, because I go to a vocational school. I don't have $100 right now to buy a replacement, I would buy a analog board online and steal the flyback, but still its a little over pricey. I mean $40 bucks is a lot, is there any other alternative part or anyone that has another idea for the problem. I would love to have this thing working because I have always wanted one since reference of them through shows and the popularity of them. This would not be the first one I have looked at, I'm not a noob I have worked on one in the past that also had a dead flyback because it was left in a cemetery and the screen was smashed in. It has a mother board that's in better condition but its my friends and the mother board is not the problem. I'm at a dead end what do you guys think I should do. https://www.youtube.com/watch?v=2aERGBzecyE here is a video of the sound
  2. Hi, got a Mac Plus for a great deal but all it does is make a pop kind of noise, sort of like my Mac SE did when it was working well, I believe this is the CRT turning on, it also makes a tiny little whine, some of the large caps on the left look like their heat shrink has been pulled downwards. No picture, no chime, logic board looks great though. Can someone point me to a 220-240V Macintosh Plus analog board recap list? Could the PSU and flyback transformer be an issue too?
  3. I picked up a Macintosh Plus the other day. It boots just fine, but the mouse that came with it (model M0100) doesn’t move vertically. Horizontal movement and the button work, though. I cleaned the mouse thoroughly inside and out and confirmed continuity of the mouse wire and circuit paths on the mouse board, per this post. Swapping the X and Y wire pairs resulted in the capstans controlling the opposite directions as expected but vertical still didnt work, while horizontal still did, so it’s not the sensors. Now I’m at a loss where to go from here, since everything on the mouse seems to be okay. Could the problem be with the computer? How would I go about diagnosing and fixing that?
  4. Today I powered on my Mac Plus and I heard really weak start up beep and there was this weird pattern on screen for a few seconds, then the missing disk screen showed up and it booted into a system as usual, except there was no sound. Second time I powered on the Mac there was no sound (not even quiet beep), also there wasn't any audio output from the audio jack on the back.

    Error 01FA00

    Hi everyone! I have an Macintosh Plus with analog board U.S. version and i have this error code 01FA00, I can not find information about this error. I opened the computer and only found a burnt capacitor (C 39, 0.1uf - 250v). already replace it but the problem still, any ideas?
  6. Hi everyone, I have Macintosh Plus, the screen disappears after some time and I usually just slap the side but now it doesn't work the screen Is completely blank (yes I turned the brightness to maximum amount alas nothing changes). Does somebody know how to fix it or what causes it?
  7. I just opened up a new-to-me Plus and found a MaxChill (piezoelectric fan?) glued to the side of the floppy cage. I had to rip it off to get to the screw. Can someone explain to me what this does and why I need it?

    What vintage macs do you own?

    Here i have a Macintosh SE/30s that i found on the side of the road with a bunch of keyboards. Only one of them is working but i need to save up for a Floppy Emulator drive to really get this going!Post what you got below! http://www.agoraroad.com/macforum/vintage-computers/what-vintage-macs-do-you-own/
  9. Hi, I bought Macintosh Plus (with 2.5Mb of ram) with CMS external SCSI hard drive, i also bought sealed and new system 6.0.8 floppy disks, i installed them on CMS external hard drive; when i open scrapbook or control panel or file manager, co-processor not installed error pops up, it keeps happening every time i open scrapbook or control panel or file manager. Please help me.
  10. Hi everyone So I have something that wouldn't really be considered unusual a very sick Macintosh Plus I have yet to see it boot or do anything else than try and kill it's self. I bought this Macintosh Plus off a Friend who had more money than sense and he bought it from Canada and had shipped here to Ireland, sadly he thought it would be a simple plug and play and he never heard of a step down converter. when he plugged straight in the Irish 250V socked it blow the crap out of it and he said it just popped. So 2 months later he offered it to me because he bought a UK one instead and I got it for a tidy €40 which is cheap on this side of the pond even for a broken one. On opening the machine I noticed 2 things the Fuse on F1 was blown looked burn't out and the thermistor on R39 was broken in half. so I replaced both of those think this may resolve the issue but both the Fuse and the thermistor blow again with spark's coming form the new thermistor and I new I did buy the right one but when I took a second look at the board both the Rectifier and Diode on CR20 and CR21 had heat damage on there legs, I have also replaced these and this fixed one issue the Thermistor no longer sparks but the fuse is still blowing when I plug it in. Yes I am using a step-down converter which I have tested that output's 117V to be exact so it should be safe. There is one more thing I can think of which is the Fuse trace lead's directly to 3 spick suppressing capacitor's the first one is a large one which I have just removed to test with a Multimeter (which I know isn't exactly accurate but my ESR meter is broken and waiting for a new one in the mail) and it has showing no signs of life on capacitance on the multimeter so I'm guessing this could be dead and causing the fuse to blow I'm not use it's only 0,1uf 250V this located on C38 and the other 2 are C33 and C37 are these known to case a fuse to blow ?. I would be very grateful for some in put on this analog board I have wanted a Macintosh Plus since my Grandad would let me play on his just a bit of nostalgia, also this Analog is starting to get expensive to repair and I'll need a solution soon before I've replaced everything on the board haha.

    Floppy with an X

    Hello everyone, I would like some advices before buying a Macintosh Plus. The Macintosh plus im looking forward into buying boots straight to the floppy with an X icon even though it has no floppy media. Wasn't it suppose to boot into the flashing question mark icon? thank you
  12. Trying to clean the floppy drive of a Macintosh Plus, now every time I insert a floppy it will automatically eject it. Disassembling the 800k floppy drive I realised that when I put a floppy in it, the motor doesn't spin and then the disk is ejected. Anyone know how to repair it? Any help will be appreciated.

    Finally a Macintosh Plus

    I had a few bad Macintosh Conquests lately. From a local recycler I got a Powerbook 140 & a Macintosh IIcx which don't work. The Powerbook is beyond help, the Macintosh IIcx chimes but probably needs a recap. So I was very happy to find a perfectly working Macintosh Plus for $80. Where I live they are not that common so $80 was not bad. With my trusty Floppy Emu this is currently my favourite Macintosh since it is ultra quiet (no fan and SD card drive). Currently running a 40MB Floppy Emu in HD20 emulation mode. Very Clean Inside
