While you are moving your video card: Has anyone upgraded their video card with their own chips? A store technician told me it just involves adding RAM chips. Our Mac II uses 8 412564-150 chips. I'm not sure, but I believe these must be twin-ported 150ns 64K*4 chips. I looked in BYTE briefly for this type of chip, but I didn't see it for sale (not even at JameCo). I saw other twin-ported 64K chips for $4 each (41266?). Thus, in principle, you should be able to buy the chips for (?$32) and (*CAREFULLY AVOIDING STATIC DISCHARGE*) put them in yourself. Has anyone done this themself? Apple charges over $100 for the upgrade. Don Gillies {ihnp4!uiucdcs!gillies} U of Illinois

I picked up a set of NEC 41264-12 chips from the local Heath-Zenith dealer. Paid about $70 for the set, and they work fine. I've heard that these same chips can be had for $45 or so by mail order, but I don't have any addresses or phone numbers on hand.

New Image Technology (301-464-3100) will sell you the chips to do this for $64. This is not a product they normally market - they are doing this as a "convenience to their customers". If you're not already a customer, I guess buying the chips from them makes you a customer :-) If the receptionist doesn't know what you are asking for, you may need to talk to Mike. (You can tell them I sent you.) Disclaimer: I do freelance software development work for New Image Technology, but I don't make any money if you buy video rams from them.
