Thanks guys. We just shipped a kit and a board, the last of the original 25 kits I bought material for couple months ago. I have more kits available now; and we will assemble boards for an additional fee. (actually, MrsCrossroads does the assembling). I'm out of 3mm LEDs, have more on order, will be ready to ship again around the end of the week.
The onboard USB/Serial adapter is an FTDI base module from MIKROE. Off board, the pins are set up to accept an FTDI Basic directly, or other chip types if an pin adapter cable is used. I have both onboard modules with USB Mini connector, and offboard with USB Micro connector, available.
I like the 1284P for the reasons listed above - 16K SRAM, great for dealing with huge arrays; 32 IO pins, so a project with more IO needs can be done without needing another chip or two; and the dual hardware serial ports for fast IO to two devices without having to resort to bit banging serial.
Links to the core files and modified pins_arduino.h are here.
(not sure INPUT_PULLUP for internal pullups was updated in these files, I just use digitalWrite to enable them).
