All, I have 4 Mac Classic II that I am working on. All have been recapped and run through ultrasonic cleaner. I have 1 fully functioning logic board. I have used that logic board to check all the other analog boards/speakers. All speakers/screens function with this board so I know it is a...

I have three different SE FDHDs that I have been refurbishing over the years and noticed that they all suffer from the same problem. After successfully booting to desktop and running for a short time (5 - 10 minutes) they will all end up freezing with a person unable to move the mouse or use...

Hello all, I'm recapping three Mac 128k analog boards. I took the easy path and ordered the cap kits from Console 5. I am on the 2nd board and noticed that the old C6 (22uF 50V) cap has a resistor attached to it. The other two boards did not have the resistor attached and the old capacitor...

Hello all, I have two 128k boards that I’m working on. The first will bong on startup with SadMac 04919A. 04 = Memory Test-Mod3 test and identifies a bad chip or chips. A sub code of 000A sub code meaning is Line 1111 (I don’t understand what that means). Also, I don’t understand the...

Hello all, I have a Mac IIfx that has been recapped with an Apple 630-4222/630-4230 high resolution display video card installed that has also been recapped. The computer runs fine. I am using an apple color plus 14” display (M1787) and getting vertical lines on the screen. I know the...

Recapping another IIci board and noticed that one of the small black diodes is missing from Q3. I assume it is the same diode that is on D3, D4, D5? I need to purchase a replacement, but haven’t figured out what to purchase. Any help would be appreciated. I have attached some pictures for...

I have had a project IIci for quite some time. I recapped it and ran it through the ultrasonic cleaner; the board looks very clean. When I go to start it, I simply get a click; either from the soft start on the keyboard or the power button. I figured it was a bad PSU, since they seem to go...

I had a friend drop off a color classic board with some really bad cap leakage. I am trying to save the board so I took the caps off and everything looks okay except down at c9 and c10. I can put solder mask over the exposed traces at c9 and the pad that was gone at c10 is the negative side...

Hello all, I accidentally removed the L221 inductor from a Mac IIsi PSU when I was removing caps and don’t know what value it was. If anyone can point me in the correct direction, it would be much appreciated. I have circled it on the photo for reference.

Hello, I finished a couple of recaps of SE 30 boards. One is working and the other is showing me the posted picture on screen with a normal start up chime. The problem board has been run through the ultrasonic cleaner. I have swapped out the RAM with known working RAM from another board and...

I just ran into something that I haven’t seen yet, any help would be appreciated. Mac SE FDHD, logic board had removable battery type.  Not the soldered battery.  Running 6.0.8 with a Blue SCSI hard drive. I replaced the battery, no corrosion visible.  Cleaned machine and rebooted.  Everything...

I have a Mac Classic that I'm working on.  I've recapped the logic board, cleaned it up (with ipa) and placed it back in the machine.  I now get the "ding", which was missing previously, upon boot up.  However, prior to the recap I was looking at a checkerboard pattern screen; now I'm looking at...
