  A selection of programs for the Commodore Pet 4032 and emulators.  
A mixture of other people's programs and some of my own.
These are available in a zip file containing a .d64 disk image, a .tap tape image and a BASIC listing which can be typed in on a real Pet. Alternatively, a separate pdf file of the listing can be downloaded.
There are 27 programs on this page and a further 23 programs on page 2.
These programs have been used on my CBM 4032 with 4040 disk drive. They may or may not work on other models.
 
There is a compilation disk with all the program on this page at the bottom of the page.
 
  Acey Deucy  
Description: Bet on the turn of a card. To win, the third card must be "inside" the other two. For instance, if a 6 and a 10 are displayed, only 7, 8 and 9 will win. If the two cards are adjacent, such as 8 and 9, no card can win so you should bet nothing. Instructions and demo at start.
Option to include the computer as a second player.

  Domino Run  
Description: Guess whether the next domino will have a higher or lower value than the one before. Each of up to 4 players in turn chooses from 1 to 5 guesses. The first domino is displayed and the player guesses higher (press H) or lower (press L). If wrong, the next player takes their turn. If right, the player continues until all the chosen guesses have been used. On completing the full number of guesses, the player scores points - 1 for 1 guess, 2 for 2, 5 for 3, 10 for 4 and 25 for 5. Failing to complete the run scores no points. There is no limit to the number of games.
Any of the players can be the computer - enter the player's name as CBM - and this feature can also be used for a demonstration.

  Egyptian Arithmetic  
Description: From an article by Didier Heroux in l'Ordinateur Individuel in discussing a method of multiplying by adding and subtracting. The method for division was developed from this.
The idea is that the ancient Egyptian had no knowledge of multiplication but could halve a number (rounded down to a whole number) or double it. To multiply number A by number B they would halve A until it was 1, doubling B each time. Then they would add together all results of B where A was an odd number.
Multiply 19 (A) by 80 (B). Count A B Result  
A is odd, so add B. 0 19 80 80  
A is odd, so add B. 1 9 160 240  
A is even, so ignore. 2 4 320 240  
A is even, so ignore. 3 2 640 240  
A is odd, so add. 4 1 1280 1520 A is 1, so stop.

  How to read the listings  
Commodore program listings were notoriously hard read with cursor and colour codes represented by graphics symbols. It was also difficult to see the number of spaces or graphics characters.
The listings for Commodore programs in BASIC were produced using my own software which converts display symbols to words. Click here for details.
