Simple GAL Programmer
比较古老的gal编程器，利用并口的，还在提供原理图和源代码，喜欢的研究下动动板做的，作者布局挺整齐的

gal的结构图
原理图，不是很复杂
和并口的接线图
还可以用这个烧写pic芯片
bom列表
上位机程序
，里面有源代码，汇编的哦
GAL assembler (16V8, 20V8 and 22V10)
操作命令，英文的
Programming a GAL
Confirmed DevicesDeviceABCD
GAL16V8OKOKOKOK
GAL20V8?OK??
GAL22V10-OKOK?
PGAL <jedec file>
Run pgal.com with a JEDEC file, then a message that request to put a GAL device will displayed. Put a GAL on the socket and type any key, start to program. When the programming was finished with successful, remove the GAL from socket. A 20-pin GAL is put on the socket with adjust GND pin. RIght list shows the devices that confirmed to program.
Reading a GALPGAL /R
PGAL /R > <file>
Run pgal.com with /R switch and dislpays a GAL type selection menu. Select a required device, display a message that request to put a GAL. Put a GAL on the socket and then type any key, starts to reading, output fuse data and terminates program. Fuse map is output to console, so that please redirect to a file.
Erasing a GALPGAL /E
To erase a GAL, run pgal.com with /E switch. But GAL is erased before program so that this command is not used normaly.
Read and Write PICPICW84.COM is a control program for program to the PIC. Its usage is same as GAL programming. Hex-file format must be INHX8, and it must includes a configuration word.
正是我需要的谢谢。。 好资料,谢谢楼主分享
