    Sad Mac 040002

    There used to be arguments among memory upgraders about whether to use sockets or not. There are some 128K boards which just don't have enough juice to drive the extra capacitance sockets add across address lines (about double that of a chip soldered directly to the board). Generally, I like...

    Old monitor = no boot on G4?

    Bunsen, your mixed RGB circuit should be the best choice. You want mostly green in a grey-scale display, then some red and less blue. Second choice is just to hook the video input to the green output. Another source of problems might be the sync lines. Some monitors use composite sync on green...

    SCSI for the 512K (or 128?)

    I wouldn't get too excited about John Bass's SCSI code. He talked and wrote about a lot of things he never actually did. I bought a copy of his driver and built one of the Dr. Dobbs interfaces and never was able to get it to work. I found that Micah was developing a commercial internal SCSI...

    Goodwill store finds

    Goodwill does ask for volunteers to come in Saturdays to help take stuff apart. That's one way to see what's behind the warehouse doors. Another way is to volunteer to help with the museum. I keep intending to do that - one of these days :beige:

    Kodak DC40 (QuickTake's brother)

    Found a Kodak DC40, which is their version of the QuickTake 100 / 150 camera. It works! However, it's a PITA to get pictures off it to the web. Kodak's PhotoEnhancer software runs under System 7.5, and the camera needs a serial port and a floppy drive, so the camera attaches to my PowerBook 520...

    Gee Three

    I never got cable select to work with my rev 1 B&W G3. I used a 40-wire cable and jumpered the drive as master on the fast channel. That worked with several of the IDE drives I tried. No slave drive. Still, it was limited to one <128GB drive, and I eventually bought a PCI IDE/SATA...

    Cube!

    Congrats on the Cube! That's a fair price for a complete system in decent cosmetic condition. Upgrades are pretty easy. 1.5 GB RAM (3 x 512MB PC 133), 120 GB hard disk, or larger with a patch in NVRAM, and so on. G4 CPU upgrades are getting hard to find as are original Airport cards. Mosey over...

    Portable wavy screen and sleep issues

    Old capacitors can cause both problems due to noise on the power supplies. Loss of sound is another common symptom. Nearly all these old girls need to be recapped by now. If you can handle a soldering iron, the procedure isn't difficult.

    Soundmaster Sounds

    Ah yes, Soundmaster and the Talking Moose! I have a couple of diskettes of sound files. Let me search for them and I'll post them online. I know I had Curly once upon a time... :lol:

    Speed Up Your AppleTalk Network

    FlashTalk was a late version of TOPS which ran the AppleTalk protocol at 2 speeds, normal 230 Kbps and triple speed. In order to maintain compatibility with non-Flash devices, the driver added a secret handshake to every normal packet. (Normal speed) Hi, can you go fast? Hi, yes I'm fast...

    alphaSyntauri

    Most of the software is already posted on 8-bit Sound and Fury website. Is there a particular archive where this should be?

    Okay, here's a strange one...

    Just to state the obvious (which is easy to overlook) the internal HD may be loading the power supply too much to boot. Old power supplies' voltage can drift and then the Mac is very screwy. Old drives can also throw an error when booting which Apple's ROM routines aren't good at recovering...

    Apple Floppy Drive Cardboard Insert for 128k Computer?

    It seems logical to assume that the insert is for 800K drives only because they are the only ones which need one. It keeps the heads from clattering against each other like castanets if the Mac is jarred. 400K drives have only one head with a felt pad to press the disk against it. The head would...

    Mystery Hardware (what is it?)

    Is there any more text under the blue capacitor at the bottom? A][ ????? What does it say at the top? Are there any hidden letters? That might hint at Apple ][ (what). It's a dual port parallel interface to something, perhaps a printer, depending on the firmware. What happens when you address...

    DVD Playback on G3 iMac?

    DVD Player is software only, and will generally work on any Mac with a Rage 128 or better and 500MHz or faster G3. It might work on an older slower model, you'd just have to experiment. My 500 MHZ iMac works, my 300 MHz PowerBook doesn't cut it.

    JB Weld + broken TiBook hinge = success

    You can't weld aluminum to steel, so solder, braze, weld, etc are no go. If both surfaces are a bit rough, brushed rather than polished shiny, I'd probably try a urethane-based glue in addition to nuts and bolts. Give it a couple of days to dry, since it drys by solvent evaporation, and the...

    Duo Dock "Gemini"

    Mine says the same. Apparently Apple went into production with the original prototype board layout.

    Symptoms of Mac Portable not getting enough juice?

    The Portable's internal regulator is a switching supply designed by Apple. I don't know what the min & max input voltages are, but it will run on as little as 5.7 V from a discharged battery and as much as 9 V. The input capacitors are 16 V rated, I think, but I'd be nervous about applying...

    A Naked and Nasty Macintosh Portable

    Thanks to Trag whose handy capacitor kits make it easy to get into fixing up these boards. If it weren't for him, my portables would still be sitting dead in the closet. :beige: When I finished recapping my first portable, I took a picture in case I needed it to document the procedure, and...

    Building a Dual Floppy Macintosh Portable

    Let's see... the PowerBook & Portable AC adapters are switching supplies, 7.5 V at various amperages. It seems the Portable's circuit can withstand 9 Volts input, because some people have run them from 9 V adapters without smoke. I haven't tried that myself. A PowerBook 100 adapter is fine...
