I'm spending some time these days on my #retrocomputing project, trying to know when the good old #v9918 VDP reads the memory. This could help emulators such as #openMSX be improved. Or perhaps I obtain exactly the same as we already know! Now I have some fun ahead trying to connect an #NMOS chip at 5v to a modern ESP32, which is CMOS and 3.3v. Level shifter ICs are too slow for these signals, so I need to use voltage dividers with the internal NMOS resistor. Fun ahead! #MSX
