This was the first computer I ever used. They had one in the library at my primary school, and I used it when I was in the 4th and 5th grade. I used to go to the library at recess so I could start loading a program from tape which would then be available for me to use when I came back at lunch time. I have very hazy recollection of what I did with this computer. Perhaps the only thing was playing a version of Donkey Kong. I didn’t know how and never learned how to program it.

Silly Job Title: Science Officer. I am the Science Officer!
In this video we continue working our way through Learning the Art of Electronics and continue working through 1W Worked Examples: DC circuits. Particularly we design and implement the 10 V voltmeter.
We use the Riden RD6006 Bench Power Supply to provide voltage for testing.
We use the EEVblog BM2257 Digital Multimeter to measure resistance and voltages.
We use the Multicomp Pro MP701033 Resistor Decade Box as our variable resistor.
We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
