A number or third-party real-time clocks already do this. The other alternative would be to use one of the parallel port control lines, but then there is more likely to be a conflict between the system software and your intentions. Consult the Hardware Reference Manual for further detail on the Joystick ports. -- George Robbins - now working for, uucp: {ihnp4|seismo|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
