Macintosh: Where To Find DRAM for Old-Style Video Boards



I want to upgrade my old 4-bit video card to 8-bit. Apple's memory upgrade kit
for the old video card is now off the price list. I assume that these are just
standard 64K DRAMs. Can you recommend a third-party source?

The memory chips used to expand the old Macintosh II Video Card from 4-bit to
8-bit are not standard 64K DRAMs. VRAMs made by NEC were used on the board
(part numbers: D41264C-12). The "-12" in the part number indicates that the
chips have a 120ns rating.

Companies that sell these chips include:

* The Chip Merchant
* SHECOM COMPUTERS
* Peripheral Outlet

To locate a vendor's address and phone numbers, use the vendor name as a
search string.
