I love this, but it's kinda the wrong direction as C64 BASIC had no instructions for gfx and sound.. it was all through pokes. I liked using Simon's Basic to get GFX on my C64 back in the day, but until I had it, I highly envied the Apple 2 and Atari BASIC commands!
Wow I had no idea there was a keyboard and BASIC ROM for the Famicom: <a href="https://en.wikipedia.org/wiki/Family_BASIC" rel="nofollow">https://en.wikipedia.org/wiki/Family_BASIC</a> It's a shame this never got released for the NES in the USA. I would have had a lot more fun with this instead of the silly Rob robot.
What fun. I was an Atari guy but I could get into something like the Apple II firmware running on something from the era with more interesting graphics and sound hardware.
