During clean up I found the receipt for my first oscilloscope. It was for a dual channel 20 MHz CRO. I bought it 20 years ago.

I would’ve been extremely happy getting it. I was only in year 11 back then. I don’t know how I convinced my dad to pay $799 for it, must have been a lot of money back then.

I bought the oscilloscope from David Reid Electronics, one of the three electronics shop that was on York St, Sydney. I like that shop, it’s sad to see that shop closed down.
