I miss those times, there was something so much more immediate, more real about computing in the 70s and 80s. It was somehow lighter and less intimidating. It's only just coming back with Arduino style kit.
RIP
Most people who have an Arduino also have a supercomputer-phone. But a ZX81 or ZX Spectrum were, at the time, all you could afford and relatively advanced to the point of being amazing for most other people (who didn't own any computer whatsoever).
I expect more people here will remember the ZX80, but what about the minimal SC/MP-based MK-14 that came before... I skipped that but got a NASCOM-1 kit the following year (1978).
I worked at Acorn in the early 80s and Sir Clive attended a couple of our infamous Christmas parties (since he knew Chris Curry).
The good thing about those old computers was the simplicity. The only thing on a NASCOM-1 between your assembly code and the hardware was 1KB of monitor program.
Had a bit of a fright after I finished soldering everything and switched it on. Nothing happened! So I laboriously went over all 1200 (?) solder joints again and breathed a sigh of relief when it worked.
I bought an old 5 bit code teleprinter and wrote a driver so that I could print by connecting the UART to a couple of transistors driving a mercury wetted relay to drive the printer. I think it would be a lot more complicated to do that on any modern computer.
