Ladies and Gentlemen,
let me introduce the final Mark1 of my Apple-1 replica, based on the STM32 ARM Cortex M4 microcontroller. As I explained in my other post about the emulator that is running on the STM32 board, this replica is inspired by the movie "The pirates of Silicon Valley". The prototype of the Apple -1 designed and built by Wozniak (Joey Slotnick) was enclosed in a wooden case, like the monitor
There are many scenes where this prototype appears, but the most fun scene is when Woz presented this prototype to his boss at HP... You should watch that movie. But for now here it is my personal model.
The mother board is a STM32F401 Discovery, powered by an ARM Cortex M4 microcontroller at 84Mhz. It has 256KB of Flash and 64KB of SRAM. The board generates a composite video signal and uses a simple 2 bits DAC for the output to the monitor. The keyboard was borrowed by a vintage Macintosh 128K, the M0110, and it is interfaced to the mother board through an Arduino mini pro that translates the scancodes into serial ASCII characters.
The monitor is a simple vintage portable b/n TV put into a wooden case. This TV set has a video input, directly connected to the video output of the mother board.
THANKS TO ALL FOR THE PRECIOUS INFORMATION IN THIS SITE!
