|
|
The GLU chip is a Programmable Array Logic (PAL) chip used to
|
|
|
|
|
facilitate I/O logic and the like. In particular, it is a PAL16L8.
|
|
|
|
|
The equation list and fusemap that can be used to program a modern
|
|
|
|
|
ATF16V8 chip is contained here.

The design file is in the CUPL programming language, named `glu.pld`.
|
|
|
|
|
It was created by reading the GLU chip as a ROM, dumping it, and
|
|
|
|
|
analyzing the output to create simplified logic equations.
|
|
|
|
|
|
|
|
|
|
The generated fuse map is included in the repository for convenience,
|
|
|
|
|
named `glu.jed`.

Kai Robinson dumped the actual GLU contents, read it as a 27C020. Rob

|
|
|
Taylor provided the proper PAL dumper board. Porchy from
|
|
|
|
|
jammarcade.net helped analyze this and converted it into a fuse map
|
|
|
|
|
proper.
