LCD Displays & IO port expansion
I'm looking into LCD displays. I found a few good ones for really cheap (overstock) from Microtips. What do I need to look for to be able to interface an LCD display with a BS2-compatible controller/driver? Which controllers/drivers are compatible? Anything that can can be controlled·via 8-Bit Direct Accessing should be fine right? Sorry, very VERY new to this stuff. Also, what is the best way to expand IO ports? I have read something about a shiftout(?)·command than can handle·select IC modules, which can be cascaded themselves as well. I would be greatful for any info. Thanks,
Blaine

Simplest I/O expansion is the 74HC595 for output and the 74HC164 for input.
