Re: Let's remake the DigiBlaster! Nice catch, SukkoPera. Unfortunately, that could be anything. I did a cursory search on ZN427s. It gave one place where you could seemingly order such an IC at around 18 EUR per piece. But here's a question. Do you want to build an exact replica or a functionally equivalent device? The first may prove impossible without access to an original board. The last has less old school glamour.
