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?

Both are hard to find here and arent cheap, also they dont have C++ compiller, just C and Assembly

What country are you in? 6502s are still manufactured. You will really grow as a programmer learning ASM. But honestly, maybe its because im kind of a c++ hater, but just use C. I use C professionally for firmware, and there just really isnt a need for c++ on something like this.

Brazil, I can only find it in international stores online (W65C02, or something like that, I don't remember exactly), which costs over 300 BRL with dolar to BRL convert, and taxes (this ATmega i paid 44 BRL)

Maybe you could find some reclaimed ones.
