-
- It is the memory configuration register. $37 means BASIC and KERNEL ROM
- are switched in, and is thus normal. $36 means BASIC is out, and KERNEL
- is in. $34 means no BASIC or KERNAL or anything: a 64K RAM machine.
- Most other configurations aren't used.

-
- It's the state of the interrupt, carry, decimal, and other flags. A
- normal configuration would be $20 (all flags cleared). This enables
- interrupts, meaning you had better have at least the KERNEL ROM switched
- in unless you have an IRQ handler already in the right place.
