NightSprinter #1 Posted July 11, 2006 (edited) Hi there, just got a Trak-Ball for the 5200 off eBay and tried to test it with Centipede (which of course is a great Trak-Ball game). Problem is, none of the keys on the keypads or even the start/pause/reset buttons will work. Would it be safe to guess that the POKEY chip is damaged somehow (since I do remember it being responsible for joystick control)? Want to get my 5200 2-port back to usable status so I can actually put the Trak-Ball and the Wico to use. Let me know if there's any solutions.

jsoper #2 Posted July 11, 2006 Does the 5200 work with a normal controller? I doubt a trackball has a pokey in it. Quote Share this post Link to post Share on other sites

NightSprinter #4 Posted July 11, 2006 He's right, a normal joystick hasn't worked. But it's not the controller where the POKEY resides, it's on the 5200's motherboard. I'm just trying to figure out if a bad POKEY would cause nonresponsiveness from a working Trak-Ball Quote Share this post Link to post Share on other sites

Ansiterm #6 Posted August 8, 2006 Do you have a source for these chips? I have a 400 on which I wrote "bad Pokey" years ago. Symptom is that it powers up to the blue screen but without notepad and won't run cartridges or anything else. I've got lots of experience troubleshooting computer hardware, so when I get some time, I was going to open it up and take a look. Having access to spare parts would be good.

eegt97 #7 Posted August 8, 2006 Do you have a source for these chips? Best Electronics is a good source. Very responsive to questions and quick shipping... -Brian Quote Share this post Link to post Share on other sites
Ansiterm #8 Posted August 8, 2006 Thanks. I remember Best Electronics now you mention it. I've been out of the Atari loop too long Heh, and a pokey chip cost $5.00 for a computer that's probably only worth $5.00. Oh well, I'll open it up just the same and have a look when I have time. I have another 400 that works fine, so I've been keeping the broken one for spare parts. (Actually, I've had them both in a closet for over 10 years.) Do you have a source for these chips? Best Electronics is a good source. Very responsive to questions and quick shipping... -Brian Quote Share this post Link to post Share on other sites
