Re: 19,008 LEDs on the wall, 19,008 LEDs

The controller will use cypress dual port SRAM.  In the case of an
Apple II it might be possible to take out all of its ram and just use
the 64k from cypress.  (Thats what I'm going to do with the altair)

The AVR microcontroller will refresh the display at 70-100hz.

I was listening to music last night and thought about a giant
vectorscope...  :)  That should be easy since the display is bitmapped
to ram in 8 bit wide increments.  All I would need to do is use an A/D
converter.  Rrotate left through carry every byte in the display's
memory, take a sample, and then set the corresponding magnitude LED on
the right side.  :)  Fairly simple and very dynamic!  Should be easy
with an AVR.  Might need a blanking interval, but with the AVR at
8MIPS, who knows...
