Mine was one of the later 6800-series - an 8-bit CISC CPU with enough 16-bit extensions to not feel too constrained. It's interesting that everything which made it a great learning platform (orthogonal instruction set, instructions for common but complex operations, ability to access lower bits of registers directly) make x64 a horrible instruction set to learn as your first. In that regard, x64 seems more RISC-like: it's intended for compilers to generate that, not humans.
