Nice try...Zuse Z3
From Wikipedia, the free encyclopedia
Zuse Z3 replica on display at Deutsches Museum in Munich
The Z3 was an electromechanical computer designed by Konrad Zuse. It was the world's first working programmable, fully automatic digital computer. The Z3 was built with 2000 relays, implementing a 22-bit word length that operated at a clock frequency of about 5–10 Hz. Program code and data were stored on punched film.
The Z3 was completed in Berlin in 1941. The German Aircraft Research Institute used it to perform statistical analyses of wing flutter. Zuse asked the German government for funding to replace the relays with fully electronic switches, but funding was denied during World War II since such development was deemed "not war-important". The original Z3 was destroyed in 1943 during an Allied bombardment of Berlin. A fully functioning replica was built in the 1960s by Zuse's company, Zuse KG, and is on permanent display in the Deutsches Museum.
After many months with Basic in my Atari 65XE I wrote small program in assembler: debugger.YES!
That was (for me) the first affordable one.
Funny side note: after my very first "Hello world" program I figured that Commondore's BASIC really sucked and directly started with Assembler.
Now THAT was fun
My beautiful C64 came third (after my ZX spectrum). It was the first computer I ever had that included, 1) a real sound chip that didn't halt the CPU 100% when making a sound 2) coloured sprites- amazing objects that actually moved across the screen smoothly deleting themselves as they went and had actual collision detection (cutting edge at the time, great for games lol)
