Space Duel

[retroshaun]

Just picked up this little beauty this morning. Fully working (more or less - see later!), gorgeous monitor with LV2000 installed. Sideart is decent, not perfect - no big scratches, just a little grimy in spots.

When I got it home, everything is working aside from the START button. It lights up, says "PRESS START" but nothing happens. I cleaned and reseated all the contacts on the cone button but thats as far as I got with it as I have a busy day ahead.

Any pointers as to what I should check?

What a beauty, I want one of those, next vector maybe If I can find one

Swap the switch with the 2 player one to start with.

Yeah thats the problem Space Duel doesnt have 1P / 2P start... just "start" (you select 1 or 2 players from the initial on screen menu, using the button below the start)

Nice score Shaun, I've got one and I love it, altho mine is my vectormame cab now

Checkout the pin out, I'd check the pin for oxidation or lack of tension for the START signal on the smaller connector. Also clean the connector pad with an eraser (can't say rubber cos you're in the states). I take it you tried putting it in self test? No bad pokeys reported?

Cheers

Notes:
------
- For testing purposes, Black Widow boards can be plugged directly into a
Gravitar harness. If you want to actually play the game, you'll have to
add 4 extra wires at P20:[8/9/K/L] for the extra control panel inputs.
- The "CABINET" pin (P20:R) is potentially interesting. I haven't played
with it, but suspect that if you tied it to GND (or left it open), you
could play the game on a cocktail cabinet.

I love to see older cabs like this still going around, hope they'll be kept safe in collectors hands for years to come

OK so what I did was turned it on, did a "select game" (to get both select and start active) and then switched the wiring on both buttons around. So select became start, start became select. After this change over, I can still change the game type selected (ie using the start button) but still cannot start a game.

Hope I have explained that properly!

Basically I have verified both buttons work just fine so its not a button or connection problem. Something specific about the start signal not getting picked up at the board.

Yep - have put it into test, everythign is A-OK aside from the start button not registering!

Will check the pinout next.

FIXED.

Cleaned connector and reseated a suspicious lookign pin (thanks for the pinout Dan!).

So - Dan - remind me how you set up your vectorMame? Do you have a webpage about it? Did you go with DOS or Linux builds?
