I investigated it on a real machine and the RESET key is connected to the reset pin of the Z80 cpu.

So to implement it in MAME, when pressing they key the CPU should be reset. Just that.

The ROM that comes with the Laser 350/500/700 is able to handle the reset and take the user to a "Ready" prompt without loosing the program in RAM.
