1980's Cathode Ray Oscilloscope -- The EIectronics Inside 34

 

 

Most people will know an old tube TV, some will know tube oscilloscopes. But how many have seen the insides of a late 80s high quality scope? Will there be any surprises in this broken model?

  • I've got an oldish (probably 90s-early 00s) scope that came from a medical imaging center sitting on the parts shelf. Thinking of turning it into a mini vector arcade machine (a la Vectrex). At least I'll know more or less what to expect when I open it!

    When researching the "pong on a chip" episode I seem to remember that's how pong came about? During a public open day at a research lab, a technician knocked up something to show a basic version of pong to demonstrate what it could do. Or something like that **Citation needed** - if I find a reference, I'll shout!

    I got to play a Vectrex a couple of years pack at the Science Museum, they are soo diffrent to other CRT displays!

    "...When researching the "pong on a chip" episode I seem to remember that's how pong came about?..."

     

    I recall that the Spacewar! video game on the DEC PDP-1 used a CRT display based on RADAR screen technology. ( 1024x1024 graphics resolution in the late 50's / early 60s. )

     

    Lyle Bickley explains the PDP-1 (and we play the original Spacewar!)

    I also seem to recall that the PDP-1 had oscilloscopes as a display option as well.

     

    Some of the early CAD program development used oscilloscopes in conjunction with light pens and GPIO buttons for user interfacing.

    I think you're referring to Tennis for Two--which was basically Pong, but played on an old radar scope! Vectrex was probably my first exposure to video games. My dentist had one in the waiting room, and I loved playing it! I finally relived a childhood dream when I found one for cheap(ish) on eBay from a seller nearby. It's a great little system, and I plan on posting about it later. Maybe I'll stream some games on Twitch!
