ExoticA is an Amiga and retro gaming/computer music interest wiki including search-able computer music collections, game and demo scene information and plenty more.
Well.. I can't see much point in C=1. Useless hw for everyday use and for retro things I prefer real retro computers :) So had to vote for A1, although Pegasos would be much better on hw side ;)
My vote goes to the C5 from Clive Sinclair. Ever since Buzz showed me his C5 collection in his garage, I've been in awe. If you see him pedalling like mad through Oxford city centre, do give him a wave!!
