The Atari Gotcha

Here you may find some information I have collected over the years for my Atari Gotcha arcade game. At the moment it is in a pretty bad shape. The back plate is lost and there are some scratches on the sides. My version has normal joysticks in stead of the boobs found on the original version on the flyer. The problem is: I have never seen another Gotcha except for the photo's in the original documentation found on the web. Is it that rare?

Here is a animated gif of a screen grab. you can see that the counters are not working.

and here is a PDF with the schematics.

This is how the board looks like.

The PCB is in a bad shape also. some chips are broken and must be replaced. But the replacements are nowhere to be found (yet...) Up tiil now, I have replaced a couple 7402's, '74 and '04 ttl chips. but I'm affraid that also a few 9316 are gone. the must be a TI equivalent in the 74xx series.

Here a closer look of the console

The coin slot of the machine

The monitor internals. it's crappy, but working. the speaker could use some work...

The place of the pcb (removed for repair) game counter and power transformer

Internals of the joysticks and the game start button

Close-up of the joysticks. Are these the first even use of joysticks on a arcade game?

after a brief observation, the counters, a few joystick control ic's and the coin ic are broken. now the time to fix things...

Up till now I was unable to spot another Gotcha i.r.l. or on the net. Is this the only surviving one? Please email me if you know one!
