Graphic Card for the Apple-1
after the teaser of some time ago, here is our last project, hoping you will like it.
As you may have guessed, this is a graphics card for Apple-1, which is well-known for not having any graphics capability, so why not fill this gap?
It is based on the popular Texas Instruments TMS9918A which gave us a bit of a hard time interworking with the 6502, solved also thanks to the tips of our friend Leonardo Miliani.
But all the hardware would have been useless without the contribution of the incredible Antonino Porcino, who prepared libraries, games and demos for the project in no time... and we are just at the beginning!
The frendly support of Francesco Sblendorio has also been fundamental, he promised me DOOM with Force Feedback :-)
The whole project is open source and is available here (the link to Nino's library repo is on the page):
Here is a short video that summarizes the capabilities of the board:
