  1. I also have 3 dead ones squirrelled away to either repair someday, or to harvest for parts. I don't need a replacement yet, but I am watching this thread with great interest.
  2. Mac IIx C3 value requested

    Thank you superj2000, very much appreciated!
  3. I recapped a IIx board a very, long, while back and thought I would fire it up tonight. So, I hooked up a monitor and keyboard, pressed the power button and ... nothing. I opened it up, checked the batteries that I had put in it when it was recapped (probably over a year [or two?!?] ago) and both were practically dead. Since it had one of TT's battery boards in it, I put in some nice, newish, fully charged batteries and I tried the start button again and ... nothing. Since it had been a while, I looked up how to 'jump start' a Mac II and when I performed that procedure, the Mac booted right up. While taking a look at things, it looked like C3 was not installed, so I checked the internet to either find pics of the cap that listed its value or the value itself. I can't believe that I did not install one, when I recapped the board, but it is just a set of clean holes where the axial capacitor C3 should be AND I cannot find the values (I would like both uF and voltage). If anyone either knows what it is, or can check their Mac IIx board and pass along the values, I would appreciate it. I did find copies of the II/IIx startup circuit that list it as 47uF, but I would appreciate an answer that is based on what was physically installed or successfully used as a replacement.
  4. I don't know if re-capping will fix the issue, but it needs to be done and it will give you one less issue to be concerned with. When I get a 'new' machine that needs caps, I don't even turn them on, prior to re-capping it. My theory is that if there are no errant voltages from the bad caps, then there is less chance of issues occurring downstream. I do this with machines that historically need caps e.g. SE/30, LCIII, Mac II, etc.
  5. That is good information - it helped me, since I had been wondering about Apple ][ booting, after getting a couple of them last year and testing the drives. I thought that this might be the case, but had not looked into a definitive answer.
  6. The dual USB iBook was the first 'icebook', those iBooks previous to it were all 'clamshell' models. I have found the clamshell varieties to be pretty durable, with the exception of: 1) the power supplies (it always pays to have a voltmeter handy to check them periodically and replace when necessary) 2) tiny stress cracks around the hinges 3) the CFL backlights can dim from age and need to be replaced 4) keyboards, CD/DVD fascia become fragile over time, so be especially careful with those pieces 5) those crazy little apple logos (the leaf or the apple) come loose and fall off My fav has always been the lime iBook, unfortunately, I did not get one before the prices went so high. I did snag a couple of orange ones (my second favorite color) and one of them runs really well as a Linux computer, the other runs OS9.
  7. None of these have what appear to be original caps, even the one on the bottom, with electrolytic caps do not appear to be the 'stock' caps, unless they are missing their markings. https://www.flickr.com/photos/66071596@N00/3847352863/in/photostream/ above is a link that displays an original board prior to re-cap.
  8. 2 x Macintosh Plus and an iMac G4

    I love your iLamp - I had a 15" one that eventually red-shifted on me. I still miss it.
  9. StyleWriter I Problem

    Did you check the voltage of the power adapter? Mine went bad and I had to open it up and re-cap it.
  10. I am getting Mac LC III

    It has the max VRAM according to this... https://everymac.com/systems/apple/mac_lc/specs/mac_lc_iii.html and congrats, they are nice little machines
  11. CPU Upgrade / Overclocking Centris 650

    Not all of the early computers were thousands of dollars, my first home computer was nearly free - it was a TI99/4a that cost a little over $100 with a $100 rebate. I joined the local users group, through which I bought a used disk interface and between the games on disk, the few cartridge ones that I bought and programming on it, the computer was pretty useful, fun, and helped me gain an early understanding of what these microcomputers could do. Three years earlier, I had taken a computer class in high school, which consisted of spending class time writing out programs (in COBOL), typing them into a card punch machine and then once or twice a week going to the school's district office to run the program on a mainframe (once, maybe twice if you were lucky). A few years later, I lost my connection to a college Chemistry qual/quant program over my 300Baud modem, because my Mom got a phone call from one of her friends. Still, it was better than having to go wait in line at the Chemistry building to use the local teletype terminal that everyone else had to use. I credit these early experiences as the reason that I have such an appreciation of where computers, and later the internet evolved. The same issues that were there at the beginning are still there and have yet to be resolved, successfully - storage, security and equal access. I am impressed that you have gained an appreciation for these early machines and I wish you continued good luck in getting your vintage system to do what you would like to accomplish. That is what drives this community forward.
  12. Asante Mac Con issues

    There is some kind of dusting on the cream colored connector, I would check/clean that. I thought there was something in the first main card photo, but its not evident in the following main board photo, so it might be a reflection.
  13. Macintosh IIFX

    Sounds like a nice box for a very nice price - hope that you didn't have to drive too far. Good luck with the upgrades!
  14. Macintosh II batteries

    I checked a spare parts drawer and found one bare and one populated board that I was saving for when I got more Mac II's. I'd prefer to keep them, but if tt doesn't have any more, send me a pm.
  15. Macintosh II batteries

    These were an excellent way to handle the Mac II battery issue, unfortunately it sounds like they are all gone now.
