Freeware created for 8 bit machines by David.

Over the years David has written a number of software items for various 8-bit computers. Most of these are now available for free download here on this page , on Archive Org .

Planet X1 for the Commodore VIC-20.

This is a real-time strategy game David wrote for the Commodore VIC-20 some years ago , sometime around 2009. It does require a 32K RAM expander, so most people will have to use an emulator. The game was never completed, but it is in a playable stage. If you choose to “load map” it currently only loads a single map, which David created. press the “G” key to activate GPS. its download filename is here: planetx1.

Petdraw for the Commodore 64, Plus/4, C-16, PET 8032 and 4032.

Petdraw is a program that David wrote for several different Commodore machines that allows the creation of PETSCII graphics, which of course are graphics limited to the internal character set of the machine as well as the screen color limitations. However, it is amazing some of the things you can draw when you put your mind to it. its download filename is here: PetDraw Distro.

53Columns for the Commodore 64

This was just a proof-of-concept showing that you can get 53 columns of clear text on a C64 using the bit-mapped graphics mode. Similar programs have been done before showing 80 columns, but it is hard to read. its download filename is here: 53cols.

Sidkeys for the Commodore 64

This is also a proof of concept that was never finished. It allows using the incredible musical keyboard (or just the built-in keyboard) to play music and manipulate the settings on the SID chip. its download filename is here: sidkeys.

BASIC Tetris

This was just a fun experiment David did to see if David could make a functional version of Tetris on the Commodore 64 running entirely in BASIC without any machine language routines and without compiling it. Enjoy! its Download filename is here: basictetris.

Tetris for Color Maximite

Many people have asked for a copy of the Tetris program David wrote for the Color Maximite. It is included a link here, this version has been modified by Daedan Bamkin to add a few extra features. You can download it here, and its corresponding filename is here: Maximite TETRIS.

Looking for the BASIC source code for attaching an NES controller or PC joystick to your Commodore 64 ? you can download it here, and its corresponding filename is here: controllers.zip.
