    high pitched noise coming from Apple II Plus power supply

    I was gifted a Apple II Plus, it was untested by the person who gave it to me. I took the power supply out and measured the voltages which were consistent with the values written on power supply specs. I then decided to connect it to the mother board and turn it on. As soon as I did I noticed a...

    Extension Cable/Wireless Adapter Option for Keyboard?

    Hi everyone, Are there any retro wireless adapters that could be used with an ADB keyboard/mouse setup? Alternatively, are there any places that sell 5-10 ft long ADB extension cables? I have a less than ideal set up, meaning my Quadra tower is more than a few feet away from my desk. The Wombat...

    how to remove cpu from Quadra 840 AV

    Hi everyone,  my apologize for the delayed reply. Thank you all for your input. I was able to successfully get the cpu out by following trag's advice and using a flat head to gently lift the cpu out of its socket. The main reason I need to take the cpu out is that the board does not work. The...

    how to remove cpu from Quadra 840 AV

    Hello, Can someone kindly tell me how to take out the CPU out of a Quadra 840 AV? I was able to take off the heat sync, but I don't see any kind of lever or button to press to release the CPU from the board. The service manual didn't mention anything on removing the cpu either. Do I just pry it...

    Black screen upon 840 AV bootup

    If it were a dead hard drive, wouldn't it still boot up? It would just give the question-mark sign when there is no hard drive. Right?

    Black screen upon 840 AV bootup

    I tried reseating the VRAM, but I didn't hear any bong. I don't have a video card that would work with a 68k, I'll see if I can get one from somewhere. I have a schematic for the board, but honestly I have very little experience with reading schematics.

    Black screen upon 840 AV bootup

    Hi everyone, i have a Quadra 840 AV board that has been recapped and worked in the past. Recently it's been giving me some trouble. When I turned on the motherboard, I saw that the boot screen came up as expected. When I restarted the thing, all I got was a black screen...no boot up...

    How to take off CPU and heak sink off of Quadra motherboard

    Hey everyone, I'm having some trouble removing the heatsink on my Quadra mother board. I see two little notches on either side of the heat sink and am guessing that's where it is latching onto the cpu housing. It looks like it's on there pretty good and I'm not sure how to get it off without...

    Would you have to worry about terminating the drive if you use an SCSI to IDE adapter?

    Using Modern Hard Drives on Old Macs?

    Hello everyone. This has turned into an amazing thread! For the past two weeks I have been reading and re-reading people's postings to get an understand everything. I am having some troubles with my 80 pin HDD being detected by my color classic. So I read up on getting a passive terminator (the...

    Choosing a Starup Disk on OS 7.1

    Thats very interesting. I was starting to wondering if I had installed OS 7.1 incorrectly, or had a corrupt disk or something. But if you are having the same issues then it makes sense that the SCSI HDD is causing.

    Choosing a Starup Disk on OS 7.1

    I'm just using 7.1 and 7.0.1. I don't have system 7.6 or anything else to boot up with. I mainly just want to test that this thing works. once I know that it works I'll go out and find 7.6. So is this why it's not working? Cause I'm using an OS that does not support this kind of a feature? So...
