[QUOTE="gbyleveldt, post: 17758, member: 122"] Shaun, I've been messing about the design of the CPU board, but I'm not too sure how would be the best way to go about this. The old serial shift registers I used to drive 7seg displays in the past (74LS595) are actually very expensive now. The newer stuff (74LV8153) are not available locally in small quantities. I can use parallel to parallel registers, but this uses up a lot of IO on the CPU, requiring the use of a more powerful unit (a waste). Sooo, would you consider going for a 16char by 2 line LCD? They quite cheap now (sub R100 for backlit ones) and will actually be cheaper than going the 7seg LED route with serial shift registers. Anyway, lemme know what you think? [/QUOTE]
