So, at the end we get:
- 65C816 CPU operating at 16MHz completely asynchronously to Atari bus, VCC at 5V (unlike the rev.1b where ~14MHz clock is used and 3.3V),
- 512kb or 1MB of zero waitstate SRAM,
- up to around 30.5MB of storage ram - SDRAM clocked 128MHz (14.5MB and 113MHz for rev.1b),
- 512kB of Flash memory (256kB is reserved for fpga cores, 256kB for OS and New Device handler)
- 256b of I2C EEPROM for settings (rev.1c only)
- and more features implemented inside the fpga, but I don't want to describe them now.
