[Coco] CF Configuration Question

Wed Jun 26 11:10:30 EDT 2013

Very good guess. :)

The controller will let the coco boot when it is ready. Don't remember the calculations ATM, but it is just milliseconds to load.

Target is to have 512Kx8 SRAM for play space and buffers...... :)

Then all of the other **things** it will do.
