Gate Array Questions

[Highsheep]

As I just mentioned, I have a Macintosh SE, and it has some problems. After one month effort, I found that the problem is about the Gate arrow. I want to find out that if this unit can be programmed, and use what to program it? The pictures is just followed.

you're better off pulling one off a dead SE

The BBU is an ASIC - it is non programmable, it is fixed function, not FPGA or CPLD.

OK, I know about the BBU is that it can't be reprogrammed. Thanks for you guys helping
