TTL computer ROM is feature complete

A project log for Gigatron TTL microcomputer

Just because! A home computer without microprocessor

After 360 commits my coding frenzy has reached a conclusion: ROM v1 is feature complete! The kit will ship not with one but with two fast paced games: Snake and Racer. Sound improved and the serial loader is reliable, which is great for hacking and making more games. The fractal program now doubles as a clock, to give a valid excuse for keeping a unit on permanent display in the living room.

The unused ROM space is filled with three classic hires images from my previous projects. By packing 4 pixels in 3 bytes I got three images in where the ROM otherwise would only have space left for two.

This doesn't mean the to do list is empty, far from that: "make todo" lists 90 ideas I apparently still have in mind. But after 6 months of breadboard prototyping, 3 months of PCB design and 4 months of software hacking, this is a good point to shift focus again. For example, towards demonstrations, tutorials and documentation. Keep you posted.
