ps2: interpret KC 0x1f as '2'
The '2' key on my PS/2 keyoard never worked on Collapse OS, I wasn't sure why. I thought the keyboard was broken, but then I tried another one, still broken. But it's only the '2'! The KC sent is 0x1f. Is it a timing problem with the ATtiny? I have yet to wire my prototype for logic probing. Meanwhile, let's apply a band-aid.

# Gathering parts
|
||||
|
||||
* A RC2014 Classic that could install the base recipe
|
||||
* A PS/2 keyboard. A USB keyboard + PS/2 adapter should work,
|
||||
but I haven't tried it yet.
|
||||
* A PS/2 keyboard. A USB keyboard + adapter also works, if it's
|
||||
not too recent (if it still speaks PS/2).
|
||||
* A PS/2 female connector.
|
||||
* ATtiny85/45/25 (main MCU for the device)
|
||||
* 74xx595 (shift register)
