So got my Macintosh Classic up and working but when inserting a floppy in the drive it will spin for about a second then nothing. Nothing on the screen changes and I've tried another drive same thing and then when trying my floppy emu both internal and external it will just freeze when selecting...

Sorry a macintosh classic

After recapping my logic board and plugging it into the analog board the voltage for the 5-volt rail was set way too high like 6.5v (I was able to measure before it shorted) and then as I was measuring voltages snapped and Mac turned off. Now the 5-volt rail is shorted to ground. So it seems...

It's been a while but I never did end up fixing it because the logic board booted but never actually worked properly only booting from floppy disks hard drive being iffy crashing during copying processes completely unreliable

After a bit of Fiddaling, i've found that the pads for the capacitor on c5 are shorted and when testing continuity on the 5v rail and ground they are shorts so what can I to find this short to ground

After recapping my Macintosh classic I was still getting the checkerboard pattern and while I was probing for voltages the screen went out and there was no High voltage on the CRT. I did check the fuse, replace the mofset, and after checking the voltages the connector from the logic board to...

I have two Macintosh classic analog boards but one does not work so I wanted to switch it out with the working one but the yolk connectors don't work. So I was wondering do the pins line up or do I need to swap them around if I were to remodel the wires and if I'm able to what's the best way I...

I've already fully recap them analog born and the voltage I'm getting is just barely 11 volts with the pot turned all the way up and 4.3 volts. I've already replaced all IC's on the board in thoroughly clean the board with 99% IPA and lots of scrubbing. I've already replaced two diodes and...

Already done

Ok After changing those diodes it really is trying to boot because I see the standard boot screen but I'm still getting low voltage and it still has a wavy screen and won't do anything else. I probably just going to replace all the transistors and I was wondering about those transistors part...

Okay thanks I found them and do you know the specs for those diodes or the item number for them?

My mac classic ii I recently got when I turned it on it would have a wavy screen pattern and after that, I recapped all Capacitors analog and logic. I tested logic on the working mac analog and the logic board works fine. I have also replaced all ic chips on the analog board after all this and...

Ok, I've cleaned it and nothing but I've been doing some testing. I can boot off the hard drive but only the pre-made system files (Like off of a disk repair floppy) and I can copy that system file to the hard drive and boot off that but when I try to install an os it will never boot and when...

Well I've tried all the jumpers on both my drives but nothing works and I think its a logic board issue now are there any chips I should look at or anything like that.

Do you know where I can find the scsi Terminator jumper?
