First Program running on the CFT

A project log for CFT 16-bit Mini-Computer

A 1960s-style mini (decreasingly) reminiscent of the PDP-8 scratch-built out of 74xxx logic, including software.

Here's a video from 2014. It shows the CFT running its first ever program—and without the ALU at that, since I wasn't yet testing that part.

Everything was still makeshift at this stage.

The video demostrates:

The CFT doesn't need the ALU to increment registers, so a simple counter program that also triggers a ‘test success’ message is easily possible and shows off everything but the ALU.
