SEI ; disable interrupt servicing
LDA #0
STA $FF0A ; disable interrupts
ASL $FF09 ; acknowledge pending interrupts
STA $FDD0 ; set default ROM configuration
STA $FF3E ; page in ROM
JMP $FFF6 ; call reset
$80C2, but it does BASIC NEW.
Get the Ultimate Map by SVS. Get a ROM disassembly. Hard-copies sometime can be found and I'd be very surprised if it couldn't be found somewhere in the Internet.
