twh/f2 Posted May 27, 2006 Share Posted May 27, 2006 Hello everybody, I have a Atarimax Flash-Cart and a USB-Cart. Both carts work fine on my primary 130 XE (Stereo, 1MB). Now I found out that on a second totally independet Atari I can't use the flash cart. The flash tool always brings up error messages. First I thought ok, that's a problem only for the Atarimax flash cart. I tested the flash cart with a third atari and got the same result. Strange!! Only one of three 8bits can be used with the flash cart. Now I found out that it's not only a problem with the flash cart. I have the same effect with my USB Cart. Only with my primary 130 XE I can use my USB cart, otherwise programs just crash or even can't find the USB cart. What is so special about my primary 130 XE and what can I do that my other 2 Ataris (plain 130XE, 800XE) work with my carts too? What have these carts in common? I tried to switch the power adapter. With no result. Bad luck With my two other Ataris? \twh Quote Link to comment Share on other sites More sharing options...
twh/f2 Posted May 27, 2006 Author Share Posted May 27, 2006 I now organized a fourth Atari (800XL) and found out that both carts ran perfectly. So what can be wrong with my second 130 XE and my 800 XE ???? :-( \twh Quote Link to comment Share on other sites More sharing options...
Rybags Posted May 27, 2006 Share Posted May 27, 2006 A dud $D5xx line? Have you got any 32K game carts to test? Or maybe even Mac65 or Action? Or maybe a bad Write line. Quote Link to comment Share on other sites More sharing options...
Mathy Posted May 27, 2006 Share Posted May 27, 2006 (edited) Howdy TWH It's probably not the $D5xx line, as the USB cart doesn't use that one IIRC. Does it use the Phi2 signal? If yes, check out the CPU, if it come from Mexico, replace it. Or create a new Phi2 signal using a 74LS74 (see my BlackBox page and search for "Fixing Phi2, the proper way:").

Only one of three 8bits can be used with the flash cart. You might want to exchange the flash cartridge. More information here: http://www.atarimax.com/flashcart/forum/viewtopic.php?t=408 Now I found out that it's not only a problem with the flash cart. I have the same effect with my USB Cart. Only with my primary 130 XE I can use my USB cart, otherwise programs just crash or even can't find the USB cart. What is so special about my primary 130 XE and what can I do that my other 2 Ataris (plain 130XE, 800XE) work with my carts too? What have these carts in common? Both cartridges use the o2, r/w and cctrl signals. If any of those were weak or missing it would prevent those carts from working, even though rom cartridges might still work.

twh/f2 Posted May 27, 2006 Author Share Posted May 27, 2006 Mathy, I'm gonna check this tomorrow. i am now out for party but your explanation sounds very reasonable to me! \twh Quote Link to comment Share on other sites More sharing options...
+CharlieChaplin Posted May 30, 2006 Share Posted May 30, 2006 Hmm, are your 800XE and 130XE some of the "newer" XE`s - with the newer XE OS ?!? Not only that all of them (made in China) do have faulty GTIA chips, I heard that they also have some compatibility issues... -Andreas.
