Hi Ruud, Fortunately there is the cheap logic level converter from Sparkfun (and others). https://www.sparkfun.com/products/12009 This web page shows how to connect it to the Pi. https://mygeekyhobby.com/2018/08/12/pi1541-in-30min-with-almost-no-soldering/ But, yes... A Mega256 solution would probably be much less expensive. /Raj On Sat, Jan 4, 2020 at 2:18 AM Baltissen, GJPAA (Ruud) < ruud.baltissen_at_apg.nl> wrote: > Hallo allemaal, > > > > ... PI ...
