08/28/05 - A bunch of updates today. First ther was a bad bug in the debug build of reality boy, so I added beta 0.82.1 to fix the problem. I added a bunch of new patents on the VB displays, get them in the programming section. I fixed some typeos in the affine mode doc. And most of all, I uploaded the code to my affine mode demos. Hopefully someone can take this further and get a real affine mode demo going.
I spent the weekend working with my oscilloscope and the VB, it was a lot of fun. Things I learned: the clock is 20MHz on the nose, the display runs on a 8MHz clock, the display´s oscilate with a 20ms period, the interuptor flag follows a 10ms period. I have not verified it yet but I assume that refresh takes 5ms, I still need to find the right pins to probe. I have a full pinout of the mirror controller and I have a good idea of the pinout for the LED driver. I verified that none of the power and ground pins are used for a /reset line. Finaly, it apears that the unknown edge connector pin 5, follows pin 3 (WE), but I need a faster scope to verify anything.
