SDRAM
I finnally finished the sdram controller today which has been a two week
nightmare.  I'm embarrased that it took so long considering it was only
a wiring error. I want to thank Joel Kolstad for writing a second sdram
controller to check against what I was doing :)

Why SDRAM? You may be asking.
1. It's really inexpensive, large and available.
2. It just sounds cool to say "I've got 64 megs SDRAM in my C64!"
3. Because I said so.  Hah take that.

What I found interfacing SDRAM.
1. It has some really groovey burst modes that will help sprites,
blitter and  Amiga planar modes.
2. The burst modes are a total useless for any of the C64 "Cell" type
video  modes and may prevent those to run 1280x480 mode (actually slower
than regular dram's).
3. I'ts EVIL!! The only "real" memory is asyncronous  SRAM's.
