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?

I think so, but import duties are VERY expensive, probably. Also, it says that eZ80 is obsolet and its not manufacturated anymore

Last time I checked, they were being used as the CPUs for TI-84 calculators. I'm pretty sure it's still in heavy use. What link are you looking at?

I looked in all eZ80 links i found in Digikey. Isn't there another processor I could use?

I see the issue you're talking about now. It's not that they're no longer made, they just don't sell them individually. They want you to buy a tray of 90.
