Hi, Been looking for replacements for the C1 capacitor for a Mac 512 I recently got.  It looks like someone has replaced it with a 4.7uF cap in the past and this Mac has some slight screen issues (screen bounces slightly with disk access) Found a Pansonic ECWF2W395JA.  Would this be a suitable...

Hi all, I just added to my growing mac collection with a couple of 512s. One of them has a 400K drive which is totally dead and I think beyond my ability to repair.  I do have an external 800k drive I tried with it but I got a sad mac when I tried to boot off the 800K external which apparently...

Hi again ;) I have a mac plus that trips my house power soon after it's booted. From another thread I found that the likely culprits are the two small capacitors mounted vertically close to the power switch. I desoldered them last night and noticed that they are cracked. The markings on...

Hi I have a 512K that has a slight display jitter when the floppy drive is accessed and after being on for about an hour will start a nearly inaudible high pitched whine. According to Larry Pina, these symptoms are of a failing flyback transformer. What options do I have for seeking...

I have discovered a lot of oxidation or scorch marks on one of the pins of the J1 connector on my Mac Plus. Is it possible to clean this effectively or should I attempt to solder the wires directly to the analog board?

I've done virtually no soldering work in my life but have become interested in playing around with compact Macs. I have 2 now that need some work done on the analog boards, can someone recommend the basic tools I'll need to get started? Obviously a soldering iron of some kind, but Im lost when...

Hi I just received a Mac plus from Ebay. My plan is to replace my slightly dodgy 512k's Analog board with the one from the Plus until I have the time to do the necessary repairs on the 512k board. Are these boards interchangeable? Cheers!

I recently bought a Mac 512k with the 800K disk drive upgrade from Ebay and I had a few questions for the fine folks here. I thought at first it had some bad joints because the raster would sometimes go to a thin vertical line until I slapped the side. I took the back off to find one of the...
