  1. I recently acquired a TAM from Japan which works great. Inside, I was surprised to find an Interwire G3 L2 accelerator card. Unfortunately, there was no hard drive and no drivers for this card. Does anyone know where I can find a compatible driver for this card? I saw another thread which suggested that a generic Powerlogix card driver would work, but none of the drivers I’ve found actually do. The slot itself is fine, as a sonnet crescendo card that’s I have works well, but it normally lives in another machine. Second, the motherboard in this TAM is different from another TAM that I
  2. Gotcha. None of the other capacitors look bad at all. No leakage or bulging, so I’ll take your advice there. Any idea why the safety cap blew? The machine was connected to a surge protecting power strip, and the fuse (though it looks foggy in the picture) didn’t blow. Could something else have jacked up the voltage on that circuit?
  3. That’s exactly what I’m about to do. I’ll let you know how it goes.
  4. BTW, guys thanks for the tips. I’m just getting my little collection started and I’m sure I’ll be asking more questions.
  5. I think this little baby may need more love than that. After using it a little bit, one of the caps on the analog board exploded after a couple of minutes, filling my workbench with smoke. Luckily the case was open or there might have been some auxiliary damage. The machine still seems to work, and at first I couldn’t even see which capacitor was damaged. But, as I was expecting to re-cap anyway, I guess I’ll just be doing that sooner than I thought.
  6. I got it to power up! Don’t know if it’ll actually work 100% because that pin connection is not soldered, I just added some pressure to the connection by replacing the risers with ones that were about 1mm shorter and crossing my fingers. Now to see if I can get the HD20 that came with it to spin up...
  7. I reseated the ROMs, but noticed that the chip labeled RP7 on the upgrade board had its pins out of the socket. Looks like a previous owner tried to troubleshoot it by ripping out the MB and unseated them. I reseated it, but no love. I reseated the RAM as well, but still no love from the MB. I removed and reseated the SCSI upgrade, and then the memory upgrade itself and found what may be the problem. That same chip that was unseated is connected to a swiss-machined socket on the MB via y’all Swiss risers and the pin had broken off inside the socket. Any ide
  8. Hey all, I bought a pallet of old macs from a warehouse sale, and one of the machines was an old 512k with some weird upgrades. It looks like someone added more RAM and a SCSI port (which was threaded through the external floppy port hole). I can’t tell if this is one upgrade or two. I’d like to get this little machine working again, but it looks like whoever upgraded this machine made some strange changes to the motherboard, so I’m not sure if they can be undone. Is anyone familiar with these upgrades? The RAM upgrade is called Mac’s
  9. Is there a ‘master’ list of components and steps for performing this upgrade? I’ve found several ‘guides’ (including this one) which all refer to each other, and have missing or contradictory component lists. I’m looking for something like: 1. Get these tools 2. Source these components 3. Clean the board with this solvent 4. Look for these defects (or trouble spots) 5. Follow these steps I’m attempting to repair a color classic and I don’t have any spare boards if something goes wrong. I’d normally be glad to go through decades of comment
