Does the monitor chassis have a jumper to select either 15k or 24k? I think it does. Are you changing that setting to match the PCB?

Hey John

Done this before, changed position of the molex to 24khz and back to 15khz no change.

What i have read is that some Bootleg games have this problem with sync on astro city dont know if thats a fact

Hi Guys

I have a Sega astro city and bought some games recently, It seems that old games have scrambled graphics or thats not the case?

Golden axe, pit fighter . other games i like bad dudes, Solomons key tekken, work fine.  Is it something to do with the Monitor sync? the monitor of the astro city is 15/24khz its a Nanao.

Is it something i can work out from the monitor chassis? i tryed with the front panel horizontal/ vertical e.t.c but no success

it shows like scrambled graphics

Appreciate your help

I knew it wasn't Arkaniod and that you guys were wrong because of the Taito logo. That was a Space Invaders era Taito logo. Arkanoid came much later.

under old taito logo is written Taitotronics i guess was the first name of the corporation .

Hey guys thanks a lot for finding out for me

I will now look for the proper setup for the cab

greetings

Hi Guys

I am new to this forum and would like to say hello

Have found this abandoned Tatio cabinet that looks strange to me, and i have couble of questions if anyone knows?

 - Is this a dedicated cabinet or is a tatio universal?

 - it seems that is not jamma or pre jamma port. Do you think that an adapter is missing from there?

 - Its a 100v and 90v switch where is the proper position?
