Bit banger

Anyone who has seen my projects on the Atari 2600 might reasonably conclude that I have a thing for retro computing. The saying goes “it is no virtue to do with more, what can be done with less” and I can’t think of someone whose projects have embodied that more than demo coder Linus Akesson (lft). His latest demo runs on the tiniest of tiny Atmel processors, the ATTINY15. It has just 32 bytes of memory (just the registers, really) and room for 512 instructions. Yet, lft made a cool demo that runs on it, generating both video and sound. Oh, and he’s only running it at 1.6 Mhz (yes, 1.6 Megahertz). Very cool!
