I am always looking for alternative systems, simpler, easier – with an WOW! effect. Here one example from 2014.
HIVE – A kind of minimalistic self-construction computer with 3 Parallax propeller chips. Per chip 8 processors == 24 processors each 32 bit-wide , so you have 3 x 160Mips – a lot of computing power – but only little RAM. With minimal effort you have a TV or VGA graphics, sound, mouse and keyboard. A simple program runs in minutes. There is the SPIN programming language, FORTH and BASIC. A kind of hypermodern retro computer
HIVE was initially developed by Ingo Kripahle alias drohne235 and published by him as an open-source project. Here his German website: HIVE-PROJECT.DE
and here my personal experience from 2014 : http://www.tech-relaxed.com/hive-parallax/
