标题: PAL Device Reader（pal芯片读出工具）
pal芯片读出工具，看说明是可以读出pal类pld芯片的工具，通过软件可以将读出的文件转成jed格式，是不是很牛啊
工作原来是该分析输入输出时序来获取的
可惜只有rev2版的制作资料，rev3的软件暂时没找到

rev1的电路板

rev2的

这是就是rev3的
下面这些就是自作资料了，只提供pcb图，没有原理图，该可以想法转过来吧

rev2改rev3
Revision 3 Fix

This modification allows the PIC to inhibit switching until enumeration has completed. Please read all of the steps first before attemping the modification.
1.) Solder side: Cut the following trace going to pin 6 of the PIC chip socket. Use a multimeter to verify the connection has been severed.

2.) Solder side: Solder a wire between pin 16 of the 40-pin USB module socket and pin 6 of the 8-pin PIC socket.

3.) Component side: Remove resistor R2. We will reuse it in the next step, or you can simply get a new 4.7K ohm, 1/8 watt resistor to replace it.

4.) Solder side: Solder one lead of resistor R2 to the circled point.

5.) Solder side: Solder the other lead to any +5V point. This includes the area that is circled or anywhere along the vertical track that is boxed.

Be extra careful that the leads of the resistor do not touch anything else.
You could place electrical tape underneath the resistor or use heat shrink tubing or an insulating sleeve on the leads to keep them from touching other exposed tracks underneath it.
6.) Reprogram the PIC12F675 with the new firmware (main.hex):
