Hi, i intend to replace the stock fan of my Quadra 605 with a more silent one (Gelid Silent 6, 60x60x15 mm). The connector used to power the fan is J13 on the logic board and has three pins, but only two of them are connected and they are +12V (topmost pin, next to the silk screening J13) and...

Hi, as most of clips which holds the 30-pin SIMMs in place brake off by just looking at them, this has also happened to the previous owner of the Mac II logic board i'm currently working on. Has anyone a good working fix on how to secure the SIMMs in place when these tiny nibbles broke away...

Hi, i'm currently reworking a old Mac II logic board and think about how to best replace the two 1/2 AA batteries. How have you solved this? The most simple idea to me was to just wire and solder double battery clips on it and just use regular AA batteries in series: This will give the...

Hi, maybe a very noobish question - but how to change to keyboard layout on a US 7.1.1 to German? There isn't any option in the Keyboard settings: On 6.0.8 that was only possible when a International version was installed, but i thought that this changed in 7? Best regards, Egon

Hi, does anyone has the installation disks for MathWriter II? They are absolutely unable to find anywhere on the net. Someone over at the emaculation-Forum also directly contacted the author and he's also unable to provide them - he also told the poster that it would be OK to release them into...

Hi, i'm currently restoring a Quadra 650 back to it's fully glory and thinking about which heatsink to use for the 68040/33. I have two options: Option 1: Original Apple 68040 Heatsink: The stock one already on it. Option 2: Using one of these: (Aluminium, 50x50x11 mm, would glue it on top...

Hi, is there anywhere a specification on the physical dimensions of NuBus cards available? I want to create a 3D printed Nubus card which can hold a SCSI2SD (or ZuluSCSI) with the SD card available from the slot cover. As a last resort i could simply measure the Apple NuBus video card in my Mac...

Hi, i just picked up a Quadra 650 locally which is missing all of it's RAM except for the soldered 4 MiB. As i don't have any 72 Pin FPM SIMMs around, i think of buying "Offtek" branded ones which seem to be completely new sticks built out of new components. Has anyone already experience with...

Hi, are all B/W 9" Compacts using the same (e.g. interchangeable) CRT tubes? The CRT on my Plus is really worn out and i might be able to pick up one from a SE for small money, but don't know if it will fit. From pictures i saw they really look (absolutely?) similar. Cheers, Egon

Hi, i just swapped my GeForce 2MX in a DA for a (original Apple) Radeon 9000. The system boots into 9.2.2, but after it has been loaded, i'm unable to do anything with either the mouse or keyboard. The mouse can move, but no clicks are recognized. The keyboard does not work entirely. However...

Hi, i just started playing around with the IIgs (in Emulation) and have a few questions about this system, which eventually someone is able to answer: 1. As far as i understand, ProDOS is the base operating system with GS/OS as the graphical shell on top of it, similar to the combination of...

Hi, my Macintosh II seems to be dead in the water, power supply isn't starting up, even when using the jumpstart method of supplying 5 V between the white pin and ground. So my assumption is that the PSU itself has some issues. Are there any known issues with the Astec AAI3780 power supply which...

Hi, in a few days i will get a Macintosh II Revision A without memory, so i will need to order new one. I read some articles that with those early revisions it could be problematic to put 8x16 MB or 8x4 MB in it. Can anyone confirm this? According to...

Hi, as the title suggests, anyone has information about the Disk Copy 6.3 file format? I'm currently preparing to implement read and write support for images in this format in Mini vMac, but can't find any information about it. Would love to have something like...

Hi, i got a non working SE/30 (did not come up, no chime, ...). At first i thought it was a defective logic board as the caps nearly felt off just by looking at them, so i replaced all of them, but still no luck: - After powering on, the chime is played, the hard drive starts spinning up and...
