What comes with Apple's video expansion kit. Is it JUST memory - if so what kind - is it really necessary to pay $99 for the memory or can you add the memory yourself? :------------------------------------------------------------: : Tom Carstensen Usenet: tomc@mntgfx.MENTOR.COM : : Mentor Graphics Delphi: CARSTENSEN : : GEnie: XPC23637 : : : : . . . about the world we live in, and live in general. : : - Depeche Mode : :------------------------------------------------------------:

1. The video expansion is *JUST* memory. 8 41264-150 video DRAMs
Made by NEC Electronics (only supplier), 150ns access time -- o.k. to
substitute 120ns or 100ns parts.
2. I bought my own expansion for $46 ($5.50 each + tax) from FRYE's
electronics in Silicon Valley (Sunnyvale Information: 415-555-1212,
they mail-order free). I got 120ns parts for the money 3 weeks ago.
My Mac II runs great in 8-bit mode. Be careful to ground yourself
when you install the memory.
3. There is a severe shortage of *THESE* *VIDEO* *DRAMS* right now.
Most mail-order houses will quote $8-$9 EACH, or more. The DRAMs are
being sold to OEMs, and chip quotas has caused a memory shortage.
4. If the shortage has subsided, call microprocessor's unlimited
(back of BYTE). Otherwise, try calling FRYE's. Or find a local
distributor with stock-on-hand that hasn't marked up his prices yet.
