Naz80 Homebrew overview
The idea is to keep Mk I very simple, just to get the glue logic right and be able to do some basic stuff. selected chips are largely to do with what I have in my component drawers!
- 16K ROM – enough space for the program, but leaving enough for other devices
- 16K memory – more than enough! (my Zx81 had 1K!)
- 1 x UART’s for serial communication instead of screen and keyboard
- 16x GPIO pins to control other peripherals.
4 x 2K CMOS Static Ram – HM611LP-3
2 x 8K Rom – Intel D2764A
1 x INS8250N
