This provides good software transparency. The new mouse, the 1351, contains an even more clever gate array that provides the same joystick emulator *AND* analog joystick game paddle emulation. This works much better, as long as the software is prepared to play along... -- 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)
