Presented online is the Electronics Australia publication of A Basic Guide to Colour TVs and VCRs by David Botto. “An in-depth look at the operation of both colour TV receivers and video recorders”.
I scanned this so that people getting back into cathode ray sets and VHS machines could have a reference book about PAL colour signals and using a scope to measure ranges. Certainly a niche publication but valuable none the less. I can’t think of any Australia broadcast reference materials that are online.
