    Need Help Identify an E-Machines NuBus Video Card...

    I usually like knowing what I am buying before using "Buy It Now" on eBay... but when you see an E-Machines video card pop-up on eBay what will cost you $29 shipped (OK, $29.01), and there's a good chance that card is QuickDraw accelerated, then you just buy it now and figure out what it is...

    Generic IC Cross-Reference for "Proprietary" 8-Pin ICs Used in Macintosh Power Supplies

    I have a Macintosh IIci with an Astec Power Supply. During my last livestream, someone asked me if the power supply had the "infamous" daughter board... to which I had to answer yes. I think they mentioned it was due to the op amp on the board... or was it an optoisolator? I was trying to solder...
