    Apple II serial card identification

    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.

    400k drive does not detect inserted disks

    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...

    Advice regarding sparks on 512k analog board

    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...

    G4 Cube: Replacement PSU with 3.4Amp sufficient?

    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...

    changing multiplier on G4 CPU card

    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...

    black screen when booting from 9.2.2 to 10.4

    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...

    iMac G3 does not power on

    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...

    LC 475 prone to cap leakage as other LCs

    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...

    SE / SE30 PSU voltages okay?

    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...
