[ukvac] [TECH]Space Invaders cocktail to upright conversion problems
Hi,

I've finally got round to installing my cocktail [3 board] Taito PCB's into
my upright Taito cab.

I made the required adapter and when put in the cab, the picture was upside
down on attract and player 1, but OK on player 2 - as you'd expect.

Next I modified the pcb, as detailed here:
http://easyweb.easynet.co.uk/~swan/arcade/pv-ur.htm

(Inserted the three jumpers also cut the track from pin 9 IC7 going to IC1,
and put it to ground instead.)

Put in the cab again, now everything was upside down and the left, right and
fire didn't work.

Now I've remove the three jumpers, tested again, the controls work again,
but everything is still upside down.

I've altered dip switch 2, (supposed to have something to do with image
rotation) but whether on or off makes no difference.

Anybody any ideas - do I have to alter wires on the monitor yoke, or am I
missing something obvious?

Any help gratefully received as I've spent the last 5 hours doing this and
am getting slightly fed up now!!

Adrian.
