First PCB routing

A project log for Kobold - retro TTL computer

A 16 bit computer with 20 address bits and video display, from just a few TTL and memory chips. Instructions resemble 68000 / PDP-11.

Just a quick test to see how it would fit on a PCB and if it would be difficult to route. This is the CPU only. It is connected to the mainboard by the two 2 x 18 headers. Bypass caps are not yet placed.

Routing was easy, the autorouter did it within a minute ! That is, after experimenting with placement a few hours. The size is about 100 x 150 mm.
