Homebrew 6809 Computer + Terminalscope: Monitor, Disassembler

Sorry it's been a few months! The 6809 computer is now soldered onto a protoboard. It's got 512K of RAM and a 16550 UART for serial communications at 38400 baud and higher.

Also demonstrated for the first time on video is the Terminalscope, as seen on Hack A Day and elsewhere. (More info on that: http://msarnoff.org/projects/terminalscope/)

I'm in the process of writing a monitor. Currently it can examine and write to memory, disassemble from memory, execute code, display/modify registers, and continue execution after an interrupt. It can also self-program its own EEPROM via serial connection to a PC. All this in under 4K!

Eventually I'll post schematics and assembler source code. I've set up a page at http://msarnoff.org/projects/6809 to document the project.
