;================================

;================================
|

; On Apple II/6502 the interrupt handler jumps to address in 0xfffe
|
||||
; This is in the ROM, which saves the registers
|
||||
; on older IIe it saved A to $45 (which could mess with DISK II)
|
||||
; newer IIe doesn't do that.
|
||||
; It then calculates if it is a BRK or not (which trashes A)
|
||||
; Then it sets up the stack like an interrupt and calls 0x3fe
|
||||
|
||||
; Note: the IIc is much more complicated
|
||||
; its firmware tries to decode the proper source
|
||||
; based on various things, including screen hole values
|
||||
; we bypass that by switching out ROM and replacing the
|
||||
; $fffe vector with this, but that does mean we have
|
||||
; to be sure status flag and accumulator set properly
