I have a Macintosh Classic I which has been recapped, logic board and the analog board. After recapping the logic board I tested it. The thing booted up as it did prior. I moved on to the analog board as the CRT was just a bit wobbly. While testing after that recap it will seek the floppy...

Does anyone know the part number for the analog board yoke connector? This is a 630-0395 model board with the larger connector. I have one that is fairly yellow and would love to replace it.

I'm repairing a Classic logic board which corrosion hit the IC at Q1 near the SWIM chip. Before purchasing a new part I wanted to confirm that I had identified the part correctly. Does anyone know if Q1 is the -10v voltage regulator pictured on the datasheet below...

I am working on extracting images from a clipart collection called "Electronic Clipper". The images seem to be compressed with Disk Doubler and a program called SQUEEZE or possibly COLORSQUEEZE™ Decompress. The first disk user guide mentions that the collection should have a disk with Squeeze on...

Does anyone know the equivalent EPROM chip for the Macintosh II? I assume its either 4x 27C512 or 4x 27X128.

I recently acquired a Macintosh II which had a 030 accelerator card in the CPU socket. I'm wondering how to safely remove this so I can inspect underneath. Any pointers?

Normally my Mac Classic II works just fine. But if I connect up a spinning disk to the external port and attempt to copy a large number of files off to the internal SCSI2SD I get the error message "The disk at SCSI #0 has been remove while in use" and the SCSI2SD disconnects. I end up rebooting...

I recently acquired an Apple IIe. I'm trying to get it to work with my Floppy Emu but not having much luck. That said I don't really know what I am doing when it comes to Apple IIe. I last used one back in the 80's when I was 10. The Apple IIe seems to startup fine. Self-test checks out. I put...

Does anyone have one of the battery holder boards described in this document? I'd like to recreate it for my unit. http://tim.id.au/laptops/apple/legacy/macintosh_ii.iix.iifx.pdf

I recently connected a Macintosh Classic (7.5.5) to Ethernet via an Asantetalk bridge. I can successfully mount a file share from a Basilisk II VM and copy some files from the Classic to the VM. There are two odd things. 1) originally when I tried to mount a share from the Classic into the VM...

Wondering if the modern M68HC000 version of the 68000 chip family can be a drop-in replacement for an M68000FN8. Anyone tried this? I'm pretty sure the only differences is one is CMOS the other is HMOS. This Atari forum post seems to indicate it...

What EPROM parts are compatible with the Macintosh Classic logic board?

What's the best way to get source new pads for the bottom of old ADB mice that have lost them?
