O-Scope

[Gordon Couger]

This months Circuit Cellar Ink. has a design for a
logic analyzer that uses a FIFO chip. It Has adjustable
clock frequency and can store 8 bits 2K deep. It looks
like a natural for capturing ignition and injector timing.

You trigger in and wait till it fills up and then you clock it
out to a PC printer port.

It looks like a poor man's digital storage scope. It would just
have one bit resolution but that's enough for a lot of what we
want to do.
