4KB cartridge for Atari 2600
I did this project for the game I'm working on - "Berta And Butterflies".
There is a lot of designs of cartridge PCBs for Atari 2600. They are very good, reliable and battle tested. They usually need 74LS04 integrated circuit to work. It's an inverter with 6 gates and only one of these gates is used.
In my project I replaced this IC with a inverter made of NPN transistor, two resistors and one capacitor. Total cost of these elements is half the price of 74LS04 IC. If you make one cartridge for your own needs, it doesn't make a difference, but if you make 50 of them, the difference is significant...
You can find all the details here: https://github.com/vandalton/BertaAndButterflies/tree/main/hardware/atari2600-simplest-cart
Parts list:
IC2 - 2732 EPROM
T1 - BC337 - NPN transistor (I also tested BC548B - it works)
R1 - 3,3 kOhm
R2 - 1 kOhm
C1 - 100nF
C2 - 1nF
