Hi Lyle, Thanks for the videos. I did come across the Youtube videos on the 1230 and the TLA manual that you posted too. :) My logic analyzer seems to be working, except that the battery to keep the

Hi, I got this Tektronix 1230 logic analyzer for a cheap price from a Singapore electronics equipment seller. It comes with no probes or manual, just the unit. After a month of searching, I managed to

That would be RS-170a. NTSC had nothing to do with color. The 'National Television Standards Committee' was created to select the monochrome standard, then years later they worked to add color

Certanium made a solder for aluminum. Whatever it was, by the time I got it didn't work (it had a best by date), but the flux was angrily bubbling away.

I assume then that the aluminum tabs on can capacitors are tinned in this way. I always wondered how they did that. I have also seen copper plated aluminum wire.

Hello Michael, I agree with all you say, I'm aware that NTSC is the standards committee rather than the colour standard but NTSC is what the colour standard has
