Ok, I am starting to work on this again and I need help. I bought an old $5 TV from the thrift shop, and plugged it in. Initially I had static on the screen. I noticed some of the legs on the processor chips were crusty. I popped out the chips and cleaned the legs. Now I get an all black screen. sometimes on power up I get a few blue/green horizontal lines.
At this point I was thinking it was the POP rom chip. I removed that and tried to read it on a Minipro TL866A programmer. I tried to load that in an emulator and nothing. Black screen. Any ideas if this programmer will really read an Atari rom chip?
I popped out another game chip from the board and tried to read that, but I get absolutely nothing when I try and read that. No data at all!
I would like to make sure I am reading chips properly, then I would like to compare my POP chip rom with someone elses rom to make sure I didn't have bit damage.
Thanks,
Jeff
