PC Engine Chip Pinouts
This data was taken from numerous places. Special thanks to the usual PCE crew: Chris Covell, bt garner, Joann, and also to Backup Technik/GameLab magazine, from which I occasionally learned something new.
Throughout these pages you'll find abbreviations and shorthand terms for a lot of connections. Here's a guide:
|Dxx||Data (number)||Axx||Address (number)|
|/WR||Write Enable||/OE||Output Enable|
|/CE||Chip Enable||NC||Not Connected|
- Misc ICs are the two RAM chips (numbered 1, 2, and 12 for both)
Someone once told me that when you make a list of connections on a circuit it's called a netlist. So here's the netlist for each chip.
With apologies, I've forgotten what a lot of these notes mean. It's been a long time since I made them.
Oct 2009: This is the textual description of the circuitry supplying the 21MHz clock signal to the Hu6280/Hu6260.
Something to do with the clock circuit?
Clock -> R163 -> C138 -> R117 -> +5v | +> R118 -> GND | +> Hu6280 10 | +> R164 -> C137 -> R115 -> +5v +> R116 -> GND +> Hu6260 2
