65816 Build: First Code (ROM Running). Bank 0 RAM Working.

Updated: Feb 11

My address decode logic appears to be working (so far). I have a simple program running from flash ROM now.



Bank 0 RAM now running. I pulled the TXS0108E level shifter, as it wasn't pulling down the OE lines very well. I replaced it with discrete transistors (a couple for now, more to add). Also, I slightly reworked the OE and CS signals for the Flash ROM and RAM. Next: VIA and 4-line LCD output.
