-===== 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. 
- 
-==== Conventions used ==== 
-Throughout these pages you'll find abbreviations and shorthand terms for a lot of connections.  Here's a guide: 
-^ Short ^ Long ^ Short ^ Long ^ 
-|  Dxx  |  Data (number)  |  Axx  |  Address (number)  | 
-|  /WR  |  Write Enable    /OE  |  Output Enable  | 
-|  /CE  |  Chip Enable  |  NC  |  Not Connected  | 
-|  I/O  |  Input/Output  |  RAxx  |  RAM pin#  | 
- 
-  * Misc ICs are the two RAM chips (numbered 1, 2, and 12 for both) 
- 
- 
-==== The NetList ==== 
-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. 
-  * [[Hu6260 Netlist]] 
-  * [[Hu6270 Netlist]] 
-  * [[Hu6280 Netlist]] 
- 
-==== Other Notes ==== 
-With apologies, I've forgotten what a lot of these notes mean.  It's been a long time since I made them. 
- 
-Something to do with the clock circuit? 
- Clock -> R163 -> C138 -> R117 -> +5v 
-       |               +> R118 -> GND 
-       |               +> Hu6280 10 
-       | 
-       +> R164 -> C137 -> R115 -> +5v 
-       +> R116 -> GND 
-       +> Hu6260 2
