标题: 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
支持芯片

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

操作命令，英文的
Programming a GALConfirmed 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.
