Reset circuit for Amiga 500 Tower
« on: July 06, 2012, 04:05:47 AM »
The Atari ST computer has a momentary push button that resets the computer.  Basicly, there is a reset pin on the 68000 processor.  I would like to build a reset circuit for my Amiga 500 Tower.  No, I do not want to build the control-Amiga-Amiga circuit.  I would like to build a circuit that resets the 68000 cpu and that also clears the memory, just like it does on the Atari ST.

Pin 19 of the 68000 processor is the reset pin.  Just ground it for about one second and the chip resets.  But, I think the memory, and maybe a few other chips need to be reset too.  It was done on the Atari ST computer, I just wonder if it can be done on the Amiga as well.  I would like to be able to use the reset switch on the front of the tower case to reset the Amiga 500 Tower.
