Another update, this time in graphical form:
http://www.calormen.com/tmp/a2screen.jpg
w00t!
(Left to right: that's my Windows laptop on the left showing the desktop, with the screen grabber window showing what it just grabbed; USB/RS232C and null modem cables c/o retrofloppy.com; stock Apple //c, with color monitor showing the hires screen it just received.)
I borrowed the bootstrapping idea from ADTPro so you can do this from a bare-metal //c. Which is good, as I don't have any floppies. :)
TODO:
* This is just static "press a button to send a frame" mode at the moment. Need to make it stream.
* Windows app needs serious cleanup.
* Apple2 code is not doing page flipping correctly (probably minor logic bug, but I'm headed out for the day)
* Sending keystrokes upstream is untested
* As calculated, with the transfer unoptimized, it takes just under a second for one screen to come down at 115kbps. We can boost this with various optimizations
