Thanks for your timely response. I had asked on a modular synth DIY forum if there were any C64 SID modules I could incorporate into my modular, and was guided here, so I have been considering this project for a while. When I saw someone local selling it all cheap including PIC & LCD, I thought it would be a good start. I'm finding my way around the site now, and have much of the info I need to get on. One other question; the display I got with this is only labelled as 'DEM 16216 SYH-PY', the datasheet is here: http://www.datasheetcatalog.org/datasheets2/23/234199_1.pdf I was wondering which of the LCDs on your page http://www.ucapps.de/mbhp_lcd.html this would relate to? Kind regards, Rich
