It won't help him. He wants something that is not there in the ROM.

If this can help: the power-on message is stored in ROM at $80CC. The routine to show it is on $80C2.

If you're not warm-starting, why do you need to duplicate the cold/warm start screen? O.o

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.

| Computer reset and power-on message
Hi!
I'm here newbie and want to ask trivial Qs, only 2:
1. how to call reset computer?
2. how to print Power-on message - whole text ending writting READY prompt? Simple unchanged all excepts screen. I found it in C128 where leaves even inactive screen untouched... in case of C16 or Plus/4 I found only printing message ending jump to MLM. I found Basic warm start - this prints power-on message completely, but warm start means NEW and other system changes...
Thank you for your patience.
