My Homebrew Z80 Computer on a Protoboard. DinoRun Let's Play
Hiii everyone!
I have made a little PC on Zilog80 on protoboard.
Display is SSD1306 with I2C interface.
ROM is emulated via Arduino Nano (1KB).
RAM is just random 8KB SRAM
Main task in this project is make software based driver
for I2C display via "bit banging", works slowly but
works, it also depends on time which Nano response and CLK freq. (1.35MHz).
I wrote a firmware in Assembly and it takes 325 bytes.
as 17 y.o. teen I am very excited with the result, maybe in future I'll improve my little project
Next I plan to add more switches and port DOOM and make Shadow RAM and dynamic Clock (bcs nano is too slow for Z80)
Have a good day and no hate plsss :)
