Can I use a simple EEPROM for a cartridge?

[cbmeeks]

Lets say I have a stack of 8K and 32K EEPROMS.

 

If I match the pinouts, can I make my own CV carts or do I need some other logic in between?

 

Which brings me to my second question, how are /8000, /A000, etc. used on the CV? Would my cartridge have to set those somehow like with pull up/down resistors?

 

Im learning more about the CV hardware so please excuse my ignorance.

 

Thanks.

/8000 through /E000 are individually-decoded addresses representing A15-A13. If any of them are on, that means A15 is high. A14 and A13 decode as one of the other lines. So if you were to use a single 32K EEPROM, it needs to activate based on ANY of those select lines going low.

And to answer your first question, you can connect the data and address lines directly. Only chip select needs special logic to go active when one of those 4 decoded lines goes active (low).
