The Eurocom65816

What is it?

This design has been beased on version C of the Eurocom6502. Main changes:
- The 6502 has been replaced by the 65816.
- The idea rose to use the full amount of the 128 KB SRAM so I added a 74ALS573 to be able to generate the extra needed address line. Maybe overkill, but you never know....
- I added a second GAL to handle the extra RAM and RDY circuit.
- As an afterthought, I replaced the 128 KB SRAM with a 512 KB one. Same size, so why not? And now the 573 isn't overkill anymore.
