Overview
This project shows how an Atari cartridge was modified using a 24-pin dual inline package socket in order to become familiar with some Atari programming and possibly sell some homemade cartridges.
Explanation
The 20-year old Atari program is a challenge for those who wish to reprogram it due to its limitation in the size of the game where there is only 2k or 4k along with the memory and CPU power deficiency. Inside the Atari, games are programmed in assembly language for 6502 processor. This is one way of learning more about assembly/game programming even by initially doing a simple graphical output.
An old ISA I/O controller card taken from a Playstation mod was used since it contains lots of jumpers on it which can be useful between the two types of EPROMs, the 2732 and 2532. A piece of paper was used to draw how pins were being routed and how they will be routed for the 2732 EPROM support which involves cutting down to 3 jumpers or 6 pins. A few more traces were cut on the board and the specification becomes the basis of re-soldering
