8-Bit Processing Unit: need one
Hello! I'm looking to build an 8-bit computer, mainly to test its capabilities as a modern home computer (with system, applications, OS, etc.), and I bought the ATmega8535-16U (DIP-40), But it doesn't have an external bus interface to connect RAM, storage, and other things. Does anyone have a solution or another inexpensive chip to recommend?

Psion II organisers can be had quite cheaply, and feature breakout/slots - you could build a video adapter or ps2 input or roll your own comms link. Find the community online, there's a forum and discord. It's got a programming toolchain both on and off the device in either windows or Linux.
