Hello from Brasil

Hi, I am Marcelo from Brazil
I build my first computer in 1980 when I founded my company with 2 other friends from university. The omputer image is attached. (can you see the HD was a tape record? Yes, only serial data. And the monitor was an b&w TV. It was an Z80 microprocessor with 16KRam and 8KRom (yes, Kbytes and not M or G)
While in this company (uptoday) I dedicaded on commercial area so I stopped about technical matters.
Now I am retiring and I started studying electronics again (6 months now).
Learned a lot here in DronBotWorkshop, where I really found motivation to start again.
