ps2 keyboard (perixx periboard-409) proxy init/config mod by digispark attiny85

[7alken]

hi all, if anyone interested, for those who have problem with newer ps2 keyboards on some passive systems without possibility to write to the ps2 port, here is tiny quickfix at the keyboard level, so transparent everywhere ...

It now even sets fastest autorepeat and shortest delay, so I like it as on desktop :-)

this "new" PS/2 keyboard mod is of course mostly for systems which have no ability to write  to PS/2 port, as they use input shift registers (zeal8bit, tested there) ...

pls, what are best/simplest options to use PS/2 keaboard in RCBus/RomWBW ? I remember that (not only) Alan told many times that dedicateed chips are best,
or at least hassle free ... but, can be for example SC137 modified for bitbang PS2? (btw or even to SPI? I mean if there are no other GPIO to do "something")
or can also VT82C42 work at 3V3 ??

thanks,
Petr
