Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I am observing this behaviour with a 100-pin MM+. It is not present on the 64-pin version. In the console the Enter key produces some very strange results (see the picture where I have been pressing Enter only). All other keys are working normally, except for Q which almost always generates a following } character.
Looking at what Enter generates, there seems to be some sort of a pattern there.
Has anyone else seen this before?

That's a first, and very, VERY odd indeed. Noise on the keyboard clock and data lines(if you are using a KB), or bad ground on USB converter if you are using a terminal?

Are you getting this when trying to talk to the console via the console and TeraTerm, or to the console via an attached PS/2 keyboard on pins 83 and 84?

False alarm

I can be a real idiot sometimes. Had connected a modem to the exactly same pins for the UART console at the same time. Once disabled it, everything became normal
