Here's a quick and dirty table describing a pixter multimedia game cartridge that didnt use Chip On Board technology. Hopefully I (or someone else) will clean it up later.
-=- NET/FUNCTION LIST FOR PIXTER MULTIMEDIA GAME CARTRIDGE -=-
NAND MEMORY ('rom'): Matrix Memory 11247-01 http://www.matrixsemi.com/products-and-applications/documents/DS0043DMTSOPR1.11_062405.pdf Note that the PDF is a different part number. It was chosen because its the same product line and likely has the same pin interface. This is the same IC used in the JuiceBox.

(I cheated and used a local copy of a Fairchild Semi DM74LS32 pdf)

* I'm honestly confused about these; prpplague pinned the Pixter Expansion Slot without any knowledge for pin1 from the hardware, and had to guess pin numbers.
Keys:
- crt Cartridge port on the pixter MM (numbered odd pins on front; even pints on back as determined by cart PCB)
- rom ROM pin (u-shaped numbering pattern as normal for DIP ic's)
- H32 7432 pin (u-shaped numbering pattern as normal for DIP IC's)`
