I wired up a little 2k/4k multicart that uses a 74LS04 for a CE hex inverter.
It works with the AMD 29F010A-90PC and with some minor wiring changes, the smaller Atmel 28C64-15PC
However, it will NOT work with the Atmel 29C010A-12PC and I've tried several.
Sometimes I get a glimpse of the game screen before it blanks out.
An older post http://atariage.com/...ri/#entry240804
describes a similar problem (though I have a 4 switcher) and he solved it by using a 7406 inverter.
Before I take a chance on that inverter does anyone know what might be causing this problem?
I'm trying to understand why it would effect the 120ns chip but not the 90 or 150?
I really would like to use these chips since I have a few lying around.
