Hi all!
I just bought my 2nd 2600, my first being the one I bought in junior high in 1980, and I am having a blast. I got it cheap on eBay and it was listed as "not-working". I figured since I love troubleshooting and tinkering I could fix it. Well, I did and everything works except the player 2 joystick port. It seems to be stuck as if the fire button were held down. After some research on the internet, this site included, I deduced that the CO10750 chip might be bad. Before searching for one I thought I'd double check with the experts here.
For the record, I've tested a known good joystick in the port and taken the machine apart and inspected the soldering. My test was with a couple of games, namely Boxing, Joust, and Combat.They all behaved as is the fire button were stuck down, even when there was no joystick plugged in.
Thanks in advance for your input!
