- 512KiB RAM
- 640×480 display resolution with 16 colors out of 4096.

- PS/2 keyboard for user input.
- A 9-pin RS-232 port.
I target this board for the purposes of simplicity: it has everything I need to make a reference implementation of the computer. It also is quite affordable at US$150, at least until such time as they stop manufacturing it.
The big problem with the DE-1 board is it's not open source; for this reason, I desire porting the Kestrel-3 family to use open-source FPGA boards. This includes the icoBoard Gamma and MyStorm BlackIce. My vision here is a PMOD-based backplane into which you plug in one or more FPGA boards. This concept is not fully fleshed out, however; details to come as I resolve fundamental problems with this approach.
Of course, I reserve the right to change my plans depending upon changes in general hardware availability.
