===== 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 ====
{{  http://nfg.2y.net/grafx/HuChip.gif}}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
