Tiny Tim 6809 Computer

Tiny Tim is a small 6809-based computer. It consists of a 68A09 CPU running at 1.2288 MHz (4.9152 crystal), 32K SRAM, 8K EPROM, 68A50 ACIA, and 6522 VIA.

It typically communicates with a host via the serial port. Digital I/O from the VIA is brought out to a 37 pin D-shell connector on the back.

It was built in 1996 on a single-sided printed circuit board with a lot of jumper wires on the top side. It has Tiny BASIC in EPROM, with a few added commands. It can download binary files from the host and execute them.
