Was very much into home computers back when I was younger, am recently rediscovering them (and hobbyist-level electronics).
Now have Sega SC-3000H x 2, and an Amiga 500. Back in the day, I had (at various times) ZX-81, Sega SC-3000, Commodore +4, Commodore 128, then onto PCs and now Macs. Done lots of programming on the Segas: basic, machine code, even some interrupt-driven stuff to make extra-large sprites. Great fun!
