[Coco] reset behavior suggestions?

[Melanie and John Mark Mobley]

Ideas:

1)      Use a serial EEPROM to store a history.  Allow the user to make a
new selection or arrow up for history.  This is how Linux BASH history
works.  I think that this is what John R. Hogerhuis is saying.

2)      In think that a write to the reset, and interrupt vector address
should have no effect on the computer.  But this could be used to select
hardware somehow.  I think this is $FFF0-$FFFF or #FFF2-$FFFF

 

Vector Table Memory Map:

$FFF0-$FFF1 => Reserved

$FFF2-$FFF3 => SWI3

$FFF4-$FFF5 => SWI2

$FFF6-$FFF7 => !FIRQ

$FFF8-$FFF9 => !IRQ

$FFFA-$FFFB => SWI

$FFFC-$FFFD => !NMI

$FFFE-$FFFF => !RESET

 

To reset just run the following code:

   JMP [$FFFE] ; jump to address found at $FFFE and $FFFF
