    Trying to fire up my Apple II Plus

    I have had an Apple II Plus for a while, but never got around to messing with it. When you turn it on, it beeps once and the floppy drive spins and doesn't stop until you press the reset button. It doesn't load any disks, and it doesn't sound like it is trying to read the disks. I have pressed...

    Aztec LC PSU still ticking after recap

    I just recapped an Aztec PSU from a Mac LC, and when I go to turn it on, it just ticks. The solder connections look fine, is there something I am missing? The voltages I am getting are: ~4.5 from the blue wire, ~1.25 from the yellow wire, and ~.60 from the orange wire.

    SE/30 A/B Capacitors

    I am currently working on my SE/30 and recapping the PSU. I would like to replace some, if not all of the capacitors on the analog board. I see a few bright green and bright blue capacitors on the board. Could this be indicating that those are high frequency capacitors? If anyone has a list of...

    SE/30 A/B issues

    Once I recapped one of my SE/30 boards, I popped it into the machine. When I turn it on, the screen turns on and off and you can hear a click each time. The screen stays on for about half a second then shuts off then back on. When the screen comes on, the fan speed decreases from the load of the...

    Classic II Motherboard issues

    It's never worked since day 1. I have removed and cleaned and reflowed the RAM and EGRET chip, as well as a few corroded voltage regulators. I think I might have fried a ROM but don't have any spares to test with unfortunately. Any pointers?

    Replacing Portable HD with SSD/SD card

    After the hard drive in my Portable failed, it has been sitting untouched. I have plenty of spare hard drives, but they are 50 pin and the 32 pin cable on the Portable looks like it is permanently attached to the hard drive board (correct me if I am wrong). I don't want to have to mess with all...

    Compu's Conquests

    Well, I recently saw Hap selling a Portable for a pretty good price, so I snatched it up! It has a few cosmetic issues, but not in places too noticeable when sitting on my shelf. It does need work, and I will be recapping it as well as having the battery repacked. I paid $140 shipped for...

    How to start a Portable?

    Well, I feel like a complete idiot. I just bought a Mac Portable and can't even figure out how to turn the thing on. There is no power button from what I can tell. Can someone help me out? Maybe it's the battery?

    Q950 restoration project

    I'm frustrated to say the least. Why? Let's start from the beginning. I finally got a case for my various 950 parts that have been sitting for a while unused. I put them all together, and I get a chime, then an immediate death tone. It did this from the start. I removed some cards to connect a...

    Vintage TV for $5!

    I saw this at a thrift store a while back, then I came back today and it hadn't gone anywhere. I got it for $5 and it works (I guess?) It just shows static when you turn it on, since there are no longer analog signals in existence. I also found a VHF and UHF converter in a parts box of mine...

    Garage sale HAUL!

    Pretty good haul. I say it's a haul because I had to haul all this around while I went to more sales! Many people just don't put out computers until you ask. Ask and you come back with a LOT of goodies! Just a few hours Friday and Saturday and I have enough to startup a small computer shop! I...

    IIvx and Q700 Capacitors

    I need to know the capacitor values for the Macintosh IIvx and would like to know if the Q700 uses SMD electrolytic capacitors or if they are more solid and do not need replaced. Any help is appreciated!

    Socketed SE/30 board!

    I got an SE/30 from a member here for the cost of shipping. I crack it open and find this! I don't know how rare (or common) these are but it's pretty cool! I have seen these go for good money on eBay, but what is it really worth?

    Mac LC VRAM cross compatibility?

    I have this LC I motherboard I want to sell, but I also have an LC II motherboard that needs a VRAM SIMM. Can I switch the one with the LC I to the LC II? For those who don't know, this is what I am talking about:

    Finally, a Cube!

    I have been wanting a cube for a while now, and I finally found a lot of two with accessories on eBay for $200 shipped. I planned to keep two, but only kept one because I didn't have too much room. I will sell the other one with the accessories since I already have them. The great thing is they...

    Something different...

    I went to my electronics surplus shop today and my sales guy wasn't there so I was paying full price for everything. I didn't get much, just an extended keyboard and external drives. Apparently the Bernoulli drives go for 30-50, and I got them for $3.50. They have a lot more of those, so I will...

    "Suspicious" power adapters

    Got these in the mail today, $20ish for the lot. Supposedly dead, so going to reference and replace capacitors to see where that takes me. I better keep them in a box at night, since they are acting suspicious :p I just need a way to open them since I don't have a vice.

    A good day!

    I had a good day today, the same person that had the free Classic brought me an SE/30 today, free again! I also got the stuff I traded with another member here for some LC parts I repaired. The SE/30 came with a dust cover, no bite from the apple though! List of items and what I will do with...

    Vertical sweep failure repair

    I got a free Mac Classic some time ago, and on my quest to clean the garage, I have decided to fix it up to add to the collection. I glanced at the board for bad solder joints, but didn't find anything. Just to be sure, I freshened the solder on the connector to the deflector coil, still no...

    The Gift of Macs!

    I called my electronics surplus shop and was saddened to see that most of the systems I wanted were bought by someone else, however it gets better. These systems were in boxes wrapped in the garage waiting for me! Here's how the story goes: When my parents were looking for something to get...
