  1. I'm in the processing of diagnosing a floppy drive on a Classic undergoing repair that fails when trying to initialize a disk. I figured it'd be good to see if the disk was any good so I pulled out my Classic II that I recapped last year: Super! Well, let's not ruin the morning, how about the other Classic that's recapped: What an enjoyable time! It's been hot here so I'm wondering if something came unseated. I haven't cracked open the cases to inspect further yet, just figured I'd jump on here and vent first.
  2. OK, so I recently recapped my SE/30 mainboard and it went smoothly, and it resolved a weak sound issue. Little guy worked just fine. Great, I thought, I'll get ahead of the curve and recap my (Astec) PSU and analog board. That goes smoothly as well, and I resoldered a few grey-looking connectors on the ab while I was at it. Reassemble, power on... thin vertical simasimac and no chime. Weird, but OK, time for some obvious checks: - checked voltages, all rock solid coming off the ab, and the usual checks on the mb - double checked the ROM SIM and make sure it's clean and se
  3. Hi there, Recently, I picked up two SE/30 boards to repair. So far, I’ve been having trouble repairing them as both seem to have Simasimac even after cleaning and recapping them. One of the boards has the early stages (artifacts across screen) with death chimes while the other one has zebra bars and no chimes whatsoever. Both persist even when ROM and RAM are pulled out, both have no batteries, and both persist after resetting (both power and buttons on board) What steps should I take next?
  4. All – I'm genuinely flummoxed by this. Have any of y'all seen this happen before? I took a working, recapped SE/30 without a PRAM battery, installed a new PRAM battery off Amazon, and boom – simasimac on boot, no chime, even after waiting for RAM check to complete. Removed the PRAM battery, and I'm stuck with the same simasimac. Would y'all know what might have happened here, or how inserting a PRAM battery in an SE/30 that previously worked might lead to a simasimac? To make sure I hadn't accidentally unseated a ROM or RAM SIMM, I removed all of the SIMMs, soaked them and the logic
  5. So, I got a SE/30 for free since it was in pretty bad condition, screen burn in, dead HDD, and horizontal bars and no startup chime, now I've never had to restore a mac like this, my Classic II has never given me any issues (and of which i have removed the clock battery to prevent leakage) So, i quickly learned these horizontal lines are due to leaky capacitors, so i took the computer apart and pulled everything out. The insides of the computer was not good, the battery had leaked a fair bit, even causing rust on the metal frame as well as the positive battery terminal. The parts around th
  6. Hoping someone can give me some advice. Issue SE/30, no bong, video shows up but the image displayed is that of a static semi random checker board - see attached images About the machine - SE/30 no HD - Removed all old caps, axials and electrolytics and replaced axials with axials and electrolytics with tantalums. - Old caps had virtually no leaking when I received the board which was shipped in an antistatic bag - Condition of board, looks clean but was purchased as untested. I only tested after replacing caps. - Battery did not leak (no b
  7. Hi all, I had an SE/30 board recapped by MacCaps. Originally, board was no boot/no audio whatsoever. It has made progress since being cleaned and recapped, audio now works. However, I'm still left with this as a result: The startup chime is messed up, you can hear it in the following Youtube video: https://youtu.be/D_z18h5slp8 What has been done so far is the following: *Tested with three different SE/30 ROMs (2 known good, and 1 from this specific unit) *Tested with several different combinations of RAM. Since in my possession after recapping I have personally tried
