Chess Clock

[Glenn Jupp]

It's not a game, it's an application for people playing a game.

 

Chess Clock!

 

Each player uses their joystick to set their time (MM:SS:FF - minutes, seconds, sixtieths of a second), press fire when it's set. After both players are ready, press reset to go back or select to start the countdown for red/left player. Each player hits their fire button when they've finished their move. When a player runs out of time, the buzzer sounds and they lose. Then press reset to start all over again. Hours of fun (especially if each player sets their time for 99:59:59).

 

Thanks to Batari for sorting out the std_overscan.adm so this looks all neat and shiny on my cranky 2600jr.

 

BAS and BIN attached.

 

EDIT: Fixed a bonehead mistake that let those wicked, no-good, cheating players pause the countdown by holding down both fire buttons.

Is it true PAL clocks only have 50 seconds to a minute and

50 minutes to an hour?

Actually 50 - 60 - 60 makes much more sense when you consider that these are the same people that brought you 12 inches in a foot, 3 feet in a yard, and 5 1/2 yards in a rod.

You left out 50 weeks to a year.

You got my vote! I guess 25 days to a month make sense then?

One minor little nit: if the Atari is outputting 262 lines, that's 59.9227434 frames/second. If uncorrected, that would be an error of about 4.6 seconds/hour.

 

A simple correction would be to skip one frame every time (load the counter with 8 instead of 9) when the 'tens of seconds' digit is bumped to a 0, 1, 3, or 4, or the 'ones of minutes' digit is bumped to a 0, 2, 4, 5, 7, or 9. That would result in an error of 0.03 seconds/hour.
