Consider a grid:
The keys AC and BD pressed simultaneously are indistinguishable from BC and AD.Yes, I mentioned the timing.
But allowing for one key and then a second key before you release the first one is a pretty big improvement for natural typing.
Since it was polling the keyboard, among other tasks, the timing of when it looked was not entirely predictable. I was pushing the 6802 at its limit.
At least the keys did not need debouncing, they were nice keys.
The code listing has disappeared, too.
