    PowerBook 520c keyboard

    That's true. I wanted the option for a JIS keyboard instead of US. Since my last post, I found exactly what I needed for the time being - a 520c on eBay with a missing trackpad and not in the best of conditions, BUT a kana/Kanji*** keyboard and replacement LCD to donate to the 550c. I don't...

    Need help with TAM cooling fan!

    So, I had so many fans out, just for size comparisons, yeah - my scale is off. I had a couple of 1.0 and 1.2-amp fans that were obviously on the big side (~120 mm) and I didn't use them for this test. But I did have a pair of 40 mm units - 12 V @ 60 and 90 mA (not 600/900) and I know they...

    Need help with TAM cooling fan!

    Hello all, I got a second TAM last week off of one of the Facebook groups and, like the one I bought last fall, it also came well-appointed w/ a Sonnet G3/400. After some machine freezes, I took off the Fat Back and saw the frameless in the HD bracket was not on. I've since been working on...

    IIgs RAM Expansion Preventing Boot?

    As another data point, I ran the self-test (Ctrl-Open-Closed-Reset or whatever equivalent in my AEK II) and got the following: (SYSTEM BAD    09010001) which i I believe can be traced to (among other things) insufficient voltage.this after I took apart and cleaned the board (and I have that...

    IIgs RAM Expansion Preventing Boot?

    So in between working on our A/UX imaging project, trying to work through some Q950 issues and (on the side) my new SGI O2... I have a IIgs that I got in trade about six months ago that’s pretty much sat the whole time.  It’s a ROM 01 unit. MicroDrive CF card w/ 512 MB CF ByteBoosters 4...

    PowerBook G3 (Pismo) with Wegener G4 - having issues

    Basically, title. Got a couple of G3s a few months ago. One of them in great shape, 512 MB RAM, PCMCIA 802.11n card (although it only works under OS X) and a rare Wegener Media G4 at 550 MHz. The daughter card looks just like a stock one but apparently the folks over at Wegener grafted on a G4...

    3D-Printed Objects

    Note: the bezel in the picture below is not 360alaska's model! But, while a bit flimsy (thin substrate and lacking the additional stability), about 6 months ago, I ordered a bezel in "White Natural Versatile Plastic" from Shapeways for $16 USD plus S&H and was able to install it without any...

    My SE/30: w/ Turbo 040, ROM-inator, Ethernet and 8.1

    Since I am not too shy about asking for help with my myriad Quadra issues, one of the things that has been going great is my SE/30 (edit - until last week!) Here's my setup: SE/30 recapped running System 7.5.3, Mac OS 8.1 and A/UX 3.1.1 (the latter requires me to disable the 040 card) SCSI2SD...

    Quadra 950 (replacement) logic board is dead?

    Hi, Me again - I was the guy having issues with my 950's ADB port/video artifacts and SCSI2SD booting/Sad Mac: Quadra 950 board #1 The issues could be described as: (just in case y'all have any more ideas) ADB is on crack. Text carat blinks super-fast, repeats almost instantly and equally as...

    Q700 ADB or board kaput? Mouse clicks but no movement

    Certainly, @trag and @powermax: It's a Motorola XAA204, p/n FB03. Below is a picture from my other Q700, which I had in front of me at that momen. I was wrong in a previous post, the red claw connects to pin 7 of this chip, not pin 1 (judging by the orientation, marking and drawing).

    Q700 ADB or board kaput? Mouse clicks but no movement

    Bumping this in case anyone else has ideas... I worked around the issue by acquiring another Q700 but I would like to get this one working... it does have a 66 MHz crystal so the 040 and 601 PDS card run ~30% faster than stock.  Another theory - does anyone know what IC chip U54 does? It's...

    Q700 ADB or board kaput? Mouse clicks but no movement

    Sure. The ADB ports are J3 and J4. The ASIC is U12 for reference.  Good thing I can’t sleep tonight! (US-Florida)

    Q700 ADB or board kaput? Mouse clicks but no movement

    Here’s a picture of the above-mentioned ASIC 342S0440-B. I poked around the chip - each pin’s solder joint appears to be intact. I did notice the fuse above it but assume that blowing would be obvious AND be all or none?
