Hmm.. Been seeing some action with Nokia stuff for Propeller lately too.. I imagine ebay (old phones) being the best source for cheap Nokia screens. What phones should I be looking for? Or is there a better source?

Got a pretty much playable boulderdash clone going on with an 8pin pic and 3310lcd. There is only one input pin so requires a resistor network over the buttons (old trick) to use the single pin and a2d for input. I have scrolling screen, large maps, multiple levels, falling rocks/gems, working exit, collectable gems, 3 lives and titlescreen etc. The rocks/gems have different graphics for falling/still. No pin for sound but i could waste the mclr pin (eek) for that if i wanted.
Its a nice single chip handheld game, runs from cr2032 battery as well.
I can provide the init code and basic routines for both 3310 and 6100 displays. Ill try to remember to get around to posting them, but if you email me at mail at pyrofersprojects you should get a quicker response

I actually meant a source for buying the parallel control lcd setup you're describing. I appreciate the offer of the source CODE though. That's great.
I'm still a ways off from actually being able to drive an LCD from a microcontroller, but that's the direction that the parade is headed for me. I'm still learning my basic circuit analysis and understanding the analog circuitry dynamics to enable all the programmery stuff. Digital logic is my stock and trade at a higher level, but the analog stuff has confounded me for most of my life and I'm putting a stop that THAT first. ;-)
It's cheap ($10!) and 128x64 versus the 3310's 84x48 pixels. It has a parallel interface and its own on-board frame buffer RAM. It seemed like a good one to experiment with, though I'll see what I find when I get it. I ahve an unused ATmega8L here, and a handful of 8051 compatible uC's and a couple PIC's as well. I've only used the AVR chips before, so it's ALL learning here... ;-)
I'm still on the look out for a 3310 or two. I want to eventually add one to my 1541-III-DTV.
That LCD looks like a very common type. Youll probably find lots of info on using it. I will assure you though, I dont think youll find an easier display than the 3310. Its got like 8 wires on it, and 3 or 4 of them are power related. You can ignore the reset and chip enable lines, meaning you need just about a clock and data from the pic!
