turbofly Posted September 8, 2019 Share Posted September 8, 2019 Hey everybody, Some time ago was lucky enough to get my hands on an Atari XE Game System. I cleaned it up and everything worked great, with the exception of the light gun. First I thought the problem was the gun, but I tested it with Crossbow on my 7800 and it worked fine. Then I thought maybe there's a problem with my Bug Hunt cart. I later got a copy of Barnyard Blaster for the XE and it still didn't work. So now I figure that the problem must be with the XE itself. Has anybody here had any issues with using the light gun on their XE, and if so did you figure out the issue? Any suggestion would be greatly appreciated. Thanks.

Mathy Posted September 8, 2019 Share Posted September 8, 2019 Hello Turbofly Try Florian's Hardware Tester, which you can find in this posting, just to make sure the light gun works. Sincerely Mathy Quote Link to comment Share on other sites More sharing options...
+kheller2 Posted September 8, 2019 Share Posted September 8, 2019 The XE is connected to a CRT TV/Monitor right? Quote Link to comment Share on other sites More sharing options...
turbofly Posted September 9, 2019 Author Share Posted September 9, 2019 Mathy, thanks for the suggestion. I'm confident that the gun is working fine though, as it works with my Atari 7800, just not with my XE. Anything is worth a try though at this point. Kheller2, thanks for checking I know some people try to use light guns on LCD TVs, but I did have the XE connected to a CRT TV when trying to use the light gun. It's a JVC D-series, AV-32D501.

_The Doctor__ Posted September 9, 2019 Share Posted September 9, 2019 (edited) hardware testing is for the XE not necessarily the light gun itself, it may ferret out an issue preventing the gun from working... the XE might have a POKEY problem or other issue... even a power issue.. lots to check...

turbofly Posted September 9, 2019 Author Share Posted September 9, 2019 I just did some reading on the Florian's Hardware Tester. I don't have a flash cart for the XE or a disk drive, or tape drive, so it looks like I can't use that at the moment. If I come across one of those items I'll definitely give it a try.

+Nezgar Posted September 9, 2019 Share Posted September 9, 2019 Curious if you peek the values of the lightpen memory locations with the gun pointed at the screen, ie: 5 GRAPHICS 0:POKE 710,15:POKE 712,15:POKE 709,0 10 POKE 53277,0:POKE 53277,4 20 PEN=PEEK(53264):H=PEEK(564):V=PEEK(565) 30 PRINT H,V,PEN 40 GOTO 10 ( I modified the small BASIC program from here: https://www.atarimagazines.com/v3n1/lightpen.html ) 1 Quote Link to comment Share on other sites More sharing options...
