Subject: [stella] Socketed cartridge From: "J. Grand" <smooth@xxxxxx> Date: Thu, 5 Dec 1996 22:27:33 -0500 (EST) |
Hi.. This isn't directly related to the Supercharger, but it does have to do with Atari development.. I don't have a Supercharger and am trying to develop my first program for the 2600. I used a cartridge and wired a socket in place of the ROM for an EPROM or EEPROM. I made sure to connect the correct address pins, invert the chip select, etc. I used 2-3 inch wire wrap wires to connect the socket to the PCB or the cartridge. As a test, I used a 2716 (2K) EPROM programmed with Kaboom!, so I know the binary is good. When I power on the Atari, I either get blank, or just weird lines, etc. like the data is being loaded incorrectly. Just once, by sheer luck, it seemed to have loaded Kaboom! I thought it might be the speed of the EPROM, but I didn't think it should matter at such slow processor speeds.. The same with crosstalk from wirewrap wires, I didn't think the speed would be a factor.. So, basically, has anyone done this before? There doesn't seem to be a reason why using a socketed cartridge wouldn't work, so any ideas? I'm planning to find a Supercharger eventually, but for now,p this will be a fairly good alternative. Thanks! Joe smooth@xxxxxxxxxx
