Does anyone have a source for the rams used in the Mac II video cards? (Besides Apple of course) -- Tony Jacobs * Center for Engineering Design * U of U * t-jacobs@ced.utah.edu

41264 64*4 video drams are made only by NEC, I believe. Before the
memory shortage, I bought 8 for $45 from FRYE's Electronics in Silicon
Valley. They will take mail orders. FRYE's was MUCH cheaper than the
Chip merchants in BYTE/MacWeek, etc (Microprocessors Unlimited, for example).
These chips are trivial to install yourself, and you save 50% by
purchasing 8 of them yourself. I bought 120ns parts, I think even
150ns parts will work (I'M NOT POSITIVE, check your video card to get
the suffix 41264-150 or 41264-120)

The chips that Apple use are :-
NEC ( manufacturer)
D41264C - 15
These are 256K (64Kx4) Dual port dynamic rams ( 150 nS access time)
Any electronic component retailer who stocks memory chips should be able to get
them easly for you, at about a third of Apples price.
