8 | CAUTION: This code is designed to live in PROM, so initialized
|
---|
9 | variables are PERMANENTLY initialized, since the compiler assigns
|
---|
10 | initialized variables to the data segment, which ends up in PROM.
|
---|
11 |
|
---|
12 | Un-initialized variables go into the bss segment, which ends up in RAM.
|
---|
13 |
|
---|
14 | Set ON_B700 non-zero to get a Buchla 700 PROM,
|
---|
15 | or zero to get a NASA 3D Helmet Display PROM.
