    G4 dual 450MHz CPU fail

    Probably an optical illusion but some capacitors above the apple logo on the back side seem disconnected at the solder joint.

    G4 dual 450MHz CPU fail

    Pictures of the board would help

    G4 dual 450MHz CPU fail

    Was it working before it shipped? Any bent pins or missing capacitors on the CPU card?

    G4 dual 450MHz CPU fail

    I remember when I installed dual G4 processors on my Sawtooth machines you needed a specific revision board for them to work. Never owned a Gigabit G4 and from what I see they made them with single and dual G4 CPUs no idea if there is a difference in firmware between them.

    64-Pin 4MB SIMMs for Apple Display Card 8*24 GC

    Larger than what fits in VRAM I would assume (to see if the picture is cached in GWORLD RAM or paged to the HD). Uncompressed scanner capture on high settings makes large graphics files.

    64-Pin 4MB SIMMs for Apple Display Card 8*24 GC

    Try Photoshop 2.5x and load a large picture and scroll around.

    Lc and lc ii question

    Hires is fixed at 640x480 66hz so anything you feed it outside of that won't work.

    Using Magneto Optical drives on vintage 68k Macs

    One of the cool things I found ages ago at a local thrift were Avery compatible floppy drive labels.

    Should I get AppleVision 750av Display?

    1280x1024@75 Hrz is decent for a CRT. People have preferences and I stick to Sony Trinitrons but have shadow mask monitors as well. Do you really want it at the price and condition available is a question only you can decide.

    OS 9 downloads super slow no matter what?

    I kind of wonder why somebody hasn't coded Opentransport 2.0 and fixed the problem (or is it unfixable?). The WGS 95 is much faster over the network because of A/UX (and probably because of that caching SCSI card).

    Anyone ever try using OpenTransport on a Mac II?

    Honestly, I think A stock Mac II would be one hell of an OS 6 machine. I run 7.1 on my IIfx units.

    Do capacitors go bang!? Quadra 650 psu

    Anything liquid filled that gets hot quickly can explode from steam pressure. I was watching a video on GPU repair and a highly qualified tech was removing a RAM chip with a hot air workstation and even when he had a large metal heatsink over the capacitors next to the ram to shield them from...

    There was a B&W photo editing app that was popular before Photoshop but I forget the name.

    PowerPump"ACCELERATOR" from NewerTech: is it worth cloning?

    It just sits in the 68040 socket runs a 40mhz CPU at 50 and adds some cache plus has a fan.

    PowerPump"ACCELERATOR" from NewerTech: is it worth cloning?

    I think I have 2 of the Apple PPC cards and one has a cracked CPU, plus the Daystar PowerPro 601 with RAM and cache and I am NOT overclocking that thing (good luck finding a replacement if you screw it up). If you're going to clone anything on a 950, I would suggest the 68040/50 with cache...

    External Fujitsu MO Drive (Custom Case)

    That turned out pretty nice. I find external SCSI drives get more use since I have a bunch of SCSI equipped machines.

    SuperMac Spectrum - The one that started it all

    Yea, there has to be some basic functionality for video to come up at all.

    SuperMac Spectrum - The one that started it all

    I have a few very old Nubus video cards, and it seems they were designed to work with special fixed frequency monitors of the time. Finding drivers is also an issue for anything system 6.0 and older (For the Mac II which shipped with OS 4.1 ).

    SuperMac Thunder II 1600 Unboxing

    There are comic books, stamps, baseball cards etc. that have kept their value or grown over the years, but they are the very early ones in good condition. Anything mass produced and modern is worthless. It's the old original Star Wars action figure dilemma; do you open the box and play with...
