Pretty awesome Keoni!

Epic! Beats http://www.mr-atari.com/afbeeldingen/systems/2600universumkeyboard.jpg, I guess

I found some cool stuff at the thriftshop. Old phone dial disks (or whatever you call these)
I want to use them as an input device for this computer.

More progress ^.^

I wired it up to my 8 bit computer and it works like a charm! Now I can use it as an input device for more complex programs.

Documentation and device specification will be posted here:

I will xpost stuff regularly, but this page will contain more detailed information.

This is a little side project. I felt like taking a break from eZ8 assembly. The 6510 cpu is a very limited cpu, so I probably won't write a complete operating system for it.

I wrote a bootloader for the computer. I can send data using a software-defined 2 wire serial interface. Because I didn't feel like writing a PC program to send files to the computer yet I hooked up 2 buttons to the pins and entered a 22 byte blinky led program manually. After I hit the execute key the LED started blinking I am so glad that this is coming together so well.

// Pseudocode:
// Repeat 8 times
//   Wait for SCK to go LOW / Execute program if RUN is LOW
//   DOUT = 0
//   Wait for SCK to go HIGH again
//   Read bit from DIN and store to buffer
// End
// Move byte from buffer to address
// Increment address
// DOUT = 1
// Otherwise: receive another byteSCK is the clock pin
DIN is the data-in pin
DOUT is the data-out pin. I use DOUT as an acknowledge signal. After every received byte DOUT is HIGH until CLK goes low again.
