Back to electronics

I needed a change of hobby again, and pulled out all my electronics stuff. My first go-around is to bread-board a basic W65C02 + SRAM + EEPROM + LCD together. Once I cleared up my confusion about BE ("bus enable" has nothing to do with the CPU wanting the bus!) and got the contrast setup correctly for the LCD, it all worked fine and dandy up to 4MHz.

So, I (not so intelligently) thought that interfacing a joystick would be pretty simple. Not quite -- for one, it has analog to read, and I haven't done that yet. And two, I'd like to make a "device" to manage the joystick but all I have are PIC microcontrollers... so I have timing and software to deal with. We'll see where it goes from there.

Oh well, it's interesting and most definitely a challenge!
