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.
