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.

'''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'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)`
