In my recently purchased Apple IIe there was an serial card but which lacks two ICs. Unfortunately I was not able to identify the card and subsequently I could not check which ICs where originally installed on this card. Does anyone recognize this card? I searched the internet but to no avail.

My 512k is slowly taking shape. I previously repaired its 400k drive and make it insert and eject disks properly. I removed the dried grease and reapplied new one. Also as my drive lost its upper head pressure pad I made a new one from a paper based cotton bud. Now that I have a working machine...

I have an 512k Macintosh on the bench which I'm about to revive. I did not turn it on upon receiving the machine cause the analog board showed burn marks on the coil connector. I know this type of damage from my Plus but not that severe. I replaced the connector and the plug on the CRT...

I got a second Cube recently but unfortunately its missing the PSU. I want to build a replacement PSU and want to use a ready made one. I can order a 28V PSU which has a rating of up to 3.4Amps. This is around 100W. It should be enough to power a stock Cube, right? Granted, using it with an...

I want to downgrade my new G4 Cube from a active cooled 1.2 GHz CPU to a stock configuration to make it fanless. I got myself a 466 MHz CPU card from an later Sawtooth I believe. To make it Cube-"compatible" I have to raise the CPUs multiplier from 3.5 (466 MHz = 133MHz bus * 3.5) to 4.5 or 5. I...

I got myself a G4 Cube for a reasonable price. It has its problems I have to work on. One is a disc drive it was damaged in a way I never ever saw before. Someone managed to jam a floppy disk into the DVD drive. It was not visible from the outside. The only thing that was more than unusual is...

My "new" B&W tower is getting shape. I upgraded it to 1 GB RAM, found a working USB2 card and replaced the hard drive with an SSD. Also a "new" Radeon 7000 is on order. One issue I noticed is a little bit strange. I reinstalled both OS 9.2.2 and 10.4.11 in a dual boot configuration. OS9 on the...

I got myself a nice B&W G3 tower. I'll upgrade it with parts I have on hand. I have a NEC made internal ZIP drive I put inside the G3. But the drive sticks out around 5 mm. I dont think thats gonna work with the drive bezel I have to aquire. The screw holes do align and there is no other method...

Hello there, I got a Mac Plus of unknown condition recently and I'm attempting to revive it. The logic board does look good after a little deep clean. The analog board is what makes me trouble. I recapped it with Panasonic caps, replaced the Rifa and tried to start it. The moment I turn on the...

I got two early 2000 iMac G3. Both of them are in different need of repair. One powers up perfectly but has a cracked case and a scratched screen. The other one looks way better but does not power on. I could make one good machine out of the two but rather would try to repair the non-working...

I was renovating one of my Compact Macs floppy disk drive. Its gear broke in pieces. I took the chance to clean and grease it. Upon reconnect it i heard a short electrical crackling. I imeadiately shut down the machine. Upon inspecting i found an broken/chipped component on the disk drives PCB...

I got myself a lot of three LC475 and one LC. One is missing its RAM and VRAM modules, the others are complete. The batteries are flat, so I cannot test them right away. The boards look dusty but okay and they do not have any signs of cap leakage. I'd like to ask if the later LCs are also prone...

Another part in my SE30 journey. I assembled the machine and tested it. A few days ago I cleaned/lubed the floppy drive, a Sony MP-F75W, as per https:// www.youtube.com/watch?v=2LWfjsvc8OA. In the assembled machine the drive worked at first. I could read data and write data, initialize disks...

I'm in the process of re-assembling my new SE30. I recapped the analog board an and did an initial smoke test. An old HDD did spin up, so I think I didn´t screw up the analog board while recapping. I did not touch anything inside the PSU at the moment. I checked the voltages with nothing...

When things work out the way I hope I soon will have an second compact Mac, an SE30 in good working order. I want to equip this machine with an BlueSCSI and want to use it as some sort of bridge machine for my other compact Mac. I learned that a simple Mini DIN can be used build a machine to...

Hello there, I'm new to the classic Mac world and bought me an SE FDHD recently. Unfortunately this was battery bombed and probably beyond repair. I got me a replacement motherboard which once was an original Apple repair part. The board does look ununsed. I installed 4 identical 1MB SIMM...
