Euro II+ Mario Bothers jumping fault

Hi All, One of my resurrected euro+ has an odd fault. It first manifested its self when trying to play Mario Brothers. The carter keeps jumping no matter what key is selected as the jump key. When I try to load Elite the game gets to the splash screen then hangs.

No cards installed and iv tried another keyboard.

All systems check out with the dealer disk.

Any ideas?

Thanks

Hello pfaraday,
maybe a problem with Strobe or clear strobe from or to keyboard...
Check 74LS04 at position C11,
74LS02 at position A12 and
74LS74 at position B10.
Last chance maybe 74LS257 at position B7.

sincerely

Hi Iv swapped out those chips with some know good ones from another system but the fault is still there. its very odd as when typing at the prompt its all fine.

Iv also tryed other games Pack Man is fine but Star Wars behaves as if a key is stuck too.

pfaraday,

This may be way out in Left Field,
but did you happen to look at your
CPU to be sure its a 6502 and not a
65C02?

Yeah, I know its a long shot, but what the hey.

Would it be a false triggering from your game port? Do you have a joystick in it?
If not, try connecting one if you have one or make sure joystick mode is disabled in the games

I'll check out the CPU but there's no joystick. it dose it in a few games and they are set to keyboard input. On the same note is there a spec for Apple II games like there is for PC's. Will Elite run on 48Kb?
