Eprom cart - capacitor?

Recommended Posts

In reading up on making 2600 eprom carts and I've run across some posts that mention a capacitor along with the the eprom and the hex inverter? Here's what I'm using: Intel 2732a eprom, rev F pcb (from a murdered Swordquest: Earthworld cart- modified to accomodate the 2732 pinnout) and 7404 hex inverter. Do I need a capacitor as well? If so, what and where?

You do not need a capacitor on that cart (since it's just 4k.)

 

Capacitors are used on 8k and above (bankswitched) carts, as you typically need one to smooth out glitches on the address lines.
