Atari Sys 1 mainboard question with roadblasters

Archived from groups: rec.games.video.arcade.collecting (More info?)

Are there Mainboards out there (ttl ones) that do not work with the
Roadblasters Cart?
I'm getting a no cartridge error on screen.
The Mainboard was working with Marble madness before it was removed and
put in storage (don't have the MM cart to test).

Thanks,

jason

YES!!! There are some main boards that won't.

A previous post by yours truly:

System 1 TTL REV A to REV C MOD


Without this mod, the TTL Main will not run Roadrunner or Roadblasters
program cart.


1 . Cut and lift 14M pin 6, connect this lifted pin to 14M pin 16. (+5V).
2. Cut and lift 3D pin 11.
3. Connect 3D pin 13 to 4A pin 5.
4. connect 3B pin 13 to 4A pin 6.
5. Connect 3B pin 12 to 4J pin 12
6. Connect 3B pin 11 to the PAD of 3D pin 11.


Not responsible for typos but I read it a couple of times
