khryssun Posted May 24, 2001 Share Posted May 24, 2001 I plan to build an EPROM 4k cart. I don't want to build a multicart such as Bob Colbert's one with dipswitches. For my first attempt I'd like to work on a very elementary circuit. I see the stuff like this : - Build a simple circuit with a 2732 EPROM and a 7404 Invertor. Anyone got an EPROM cart and may to help me ? Furthermore, If you have some EPROM cart or Prototype EPROM Cart (4Ko only) out of their box and a SCANNER please email me a 2 sided scan (scale 1:1 - not a photo). This may help. khryssun@aol.com I wondering about on thing : Is it possible to replace the 2732 EPROM with an EEPROM ? Thanks Quote Link to comment Share on other sites More sharing options...

I wondering about on thing : Is it possible to replace the 2732 EPROM with an EEPROM ? Thanks Hi !!! Yes, is perfectly possible, and is not much difficult. Take the cartdrige slot pinout. The pinout is exactly the pinout of a 2732 EPROM, except by the chip select line, this is need to inverted. So, follow pin-to-pin connections between cartdrige slot and EPROM, except for A12. Take A12 line and use 1 74LS04 gate to invert this line and connect to pin 18 of 2732 (/CE). Your cart is ready !!! Of course you need to burn the EPROM with a game program. And you need to build a PCB with a 24 pin edge connector to plug in 2600. I hope this helps. Quote Link to comment Share on other sites More sharing options...
