Goal

Being able to program PLCC32 chips while they remain soldered to the board. The chips are commonly found in a wide range of equipment, including PC motherboards.

Connector

They can be bought online but are quite expensive, for instance on http://www.hmcelectronics.com/product/Pomona/5733. I do however own a PLCC32 to DIP32 converter. I tried to put a PLCC32 chip in there upside down. When you apply some pressure, all pins seem to connect nicely. Then the idea was born to just use a PLCC32 socket and solder some wires to it to connect it to a programmer.

Programmers

• Use an Arduino with the right sketch
• Use something from http://flashrom.org/Supported_programmers and use flashrom
• Use some other commercial programmer
