With GPIO config 2 and Randy's PCB (upverter) some keys (in C64 mode) are incorrectly mapped

[r10513]

I am using the PCB Randy designed (see https://upverter.com/design/rrossi/bmc64 ), and, in C64 mode, some keys are incorrectly mapped:

Here the wrong mapping I have found:

SHIFT 8 SHIFT 9 SHIFT 0 SHIFT + SHIFT - + the minus symbol the pound symbol @ * ^ (I mean the upper arrow) : ; SHIFT : ; SHIFT ; the equal symbol

To be sure, I have tested with two different ribbon cables (so, it is not a matter of incorrect cables), and two different PCBs. I have also reinstalled BMC 64 (stable version 3.6), from scratch, with no customizations at all (besides choosing GPIO config 2). I am using a C64C white keyboard (the one with the petscii symbol in front), with a Raspberry PI 3A

Am I doing anything wrong, or is it a real issue? If anyone has Randy's PCB, could this behaviour be verified?

Can you write one line for each key that does not work as expected with a) what you're typing b) what you expect, c) what you get. That would make it easier to understand what the problem might be. Is your keyboard type set to positional in the menu?

You are right! My keyboard was not set as "positional". Setting to positional solved the issue. Now all keys are correctly mapped.

Thank you!
