Things I've Built

Kestrel-3 Emulator

My first "real" computer. It's powered by a simple, 64-bit RISC-V processor comparable to a low-end ColdFire in overall capability. It has 16MB of RAM, and a higher resolution video display. Otherwise, identical to Kestrel-2. (Circa 2015)

Kestrel-2

My first FPGA-based design, this homebrew computer featured 640x200 bitmapped graphics, 32KB of application RAM, and a 16-bit stack CPU based on the Steamer 16 architecture. (Circa 2011)

Kestrel-1

4MHz, W65C816-based SBC build on Radio Shack breadboards as a proof of concept. 32KB of RAM, 1 VIA chip for I/O. No ROM; IPL happened through a PC which uploaded system software to RAM via a serial DMA channel. (Circa 2007)

Unsuitable

A blog engine written in ANSI Forth, implemented to more to prove a point than to be a production system. Nonetheless, it ran my blog for several years before I finally switched over to Github.
