  1. I've seen corrosion from bad caps on Cache cards cause the problem you describe. On your motherboard, there's a good chance that you have corrosion on nearby chips causing some of your problems. Can you post a high res picture of the motherboard? Cache card too if you like. Here was a cache card where one of the chips was so corroded I had to remove and resolder it back down. Then I found two traces that were broken and I repaired those. I didnt take a picture of when I was completely done after removing all the solder and making sure the solder was smooth, but you ca
  2. The simplicity is awesome. At least they use ceramic caps too!
  3. That is a crazy amount of cache for a system of that vintage. And there are diminishing returns the larger the cache gets.
  4. Nicely done and congratulations! Good work, and nice feeling to bring something back to life.
  5. Every LC I have seen (from LC 1 to LC 3) has needed the PSU recapped. This "feels" like a PSU capacitor problem.
  6. I remember waiting for 3rd party vendors to offer cache cards and I got one of the 128k ones as well. I can't recall what I paid, but I do recall it was cheaper than apple's and had more RAM. Here's mine below, I bought it from a vendor in the back of Macweek.
  7. Since we're talking the IIcis, here's a fun tidbit. An easter egg exists in the IIci ROM (I seem to recall that many 68k macs had easter eggs). If the system date is set to September 20, 1989 (the machine's release date) and the ⌘ Command+⌥ Option+C+I keys are held during boot time, an image of the development team will be displayed.
  8. I got my first IIci in 1990 and it was about a year before I got a cache card. Having used the Mac daily, I could tell the difference the card provided, which varied by application. The other thing that can help a mac feel faster is a video card, especially an accelerated one. That way the mac isn't using onboard RAM for video RAM. Combine the cache card with a good video card and the mac (back then) felt quite snappy. Today, since we're mostly using the mac for nostalgic reasons, the gain you get from either of those is really more for sentimental reasons than productivity re
  9. I can second this recommendation, his videos helped me a lot too. I also bought a junk PC motherboard for a few bucks and used that to practice on first. Honestly, after about a handful of caps and chips, you will get the hang of it - after watching those videos on techniques.
  10. Well, it’s not like you didn’t try!
  11. Oh it is fully functional, the intent of the LC was to be low cost, and that meant possibly selling the system without a hard drive, yah, someone actually thought that was a good idea. The 65Scribe guy does a very good review of this model. https://youtu.be/dCqJ6iPHus0
  12. I do now recall that device, now that I see the picture. And, agree, no surprise it is from Farallon.
  13. I do recall during that era there were people who recorded using the serial port. I found the software, I cannot for the life of me remember what the hardware (microphone to serial) part looked like. https://www.macintoshrepository.org/2623-macrecorder-hypersound-soundedit-
  14. You bring up a good point I neglected, the condition of the chip probably needs to be considered. Hot air may be better for delicate chips, as the soldering with flux will remove corrosion and possibly cause pins on the chips to break if they are frail. Though, when soldering back on, you'd encounter the same. I lost a 3080 chip on a LC motherboard using the solder method due to the corrosion. I'm currently waiting for replacement chips to come from China.
