It wasn't my first computer (that was the Commodore VIC-20), but one of my favourites was the ZX Spectrum. Looking back now it is amazing to see just how much fun can be squeezed out of 64k. I've been playing around with a revised version of my meow-meow feline rhythm machine, and got distracted. As an aside I programmed a little sketch which displays my name in the style of a ZX Spectrum font. This is then cycled through, with each pixel triggering an audio sample from the ZX Spectrum. You can play around with the sequence by destroying my name(!), and create your own 8-bit sequences. CLICK HERE TO LAUNCH 8BITGRIZZLE Here's the script, should you wish to develop your own...
