    How to get 4.5G ram in an iMac G5 iSight

    There are high density AMD only DDR3 sticks that Intel systems didn't like either.

    Driver for Mass Microsystems Quickimage 24 Nubus card

    This forum should probably have a downloads area for drivers (not pirated applications).

    $37 USB Microscope on Amazon..Great results!

    Is that native or interpolated? Plenty of old cheap units out there that are just 640x480.

    Faulty Radius PC 24X - looking for repair tips

    I don't see any fuses, or 0 Ohm resisters used as cheap fuses. Pop the ROM out and see if any connectors are mangled (since it has been removed at least once). That ROM socket is from the thru-hole era so every connector in the socket has a pin on the back of the card to check for continuity...

    Soldering iron recommendations

    Does the thing come apart? I would guess the temp sensor is nonfunctional (it is a temp controlled iron correct?) or the heater is broken.

    PowerMac G4!

    Most bullet proof glass is made from thick glass layered with plastics in between, the glass is hard and flattens the bullets while the plastic deforms and spreads out the force stopping it (or at least keeps the glass from shattering and causing splinters). Trade names only exists because you...

    PowerMac G4!

    Older vests were made of Kevlar (aramid fibers), newer ones are made of Ultra-high-molecular-weight polyethylene (UHMWPE) plus metal/ceramic plates. None that I know about are made from polycarbonate which won't stop a bullet unless it's as thick as a Kardashian butt.

    Thunder IV GX - What am I missing?

    I have a whole bunch of Supermac Thunder/24 Nubus cards that has 3MB RAM (some with DSP and most with Gworld RAM) and they are fine at 1024x768 24 bit in my IIfx, IIci, Quadra era machines. I don't game on those machines. The older slower cards go into IIx or IIcx machines just to be...

    PowerMac G4!

    I rarely had issues with second hand hard disks (I test them when I get them). One guy shipped me a whole bunch of SCSI HDs with no packing between drives and most got wacked bouncing around in shipping. Most of my problems were HD shipped with computers that were dead when I get them (at least...

    Thunder IV GX - What am I missing?

    The one thing people forget is those high end video cards are optimized for 24 bit video. https://lowendmac.com/video/thunder2gx.html "The "Toby" card is Apple's unaccelerated Macintosh II Video Card. The Thunder II GX was tested with acceleration off and on. Performance improved with...

    PowerMac G4!

    I must be the only one using newer and somewhat faster than OEM IDE drives in my G4 towers. OS9 runs fast enough on IDE and OSX 10.4.x is still usable. Now if somebody made a bootable PCI-X card (ok fine a 64 bit 33mhgz PCI slot) for a G4 with a SATA NVME slot I would probably get one. You are...

    Help with Radius Thunder IV GX 1600

    RAM chip issues probably. Check if any of the VRAM chip pins are mangled or disconnected or shorting with another pin or if any chips are hot.
