My first Sony ...

Inspired by local, i searched for a really old device, and i found it … Sony HitBit 75B. My first computer. It wasn´t the first one i used. That was a Sinclair ZX81 (Just for the younger people: That was a Zilog Z80 based system with 1024 bytes of main memory. But the computer just consisted out of 4 chips). But the Sony was my first own computer. I´ve talked enough about myself … what was your first computer?
