Granted, but the difference was well explained in posts by others.

The leads carrying the composite signal are bare, and exposed. A pair of
clip leads is all that's required to gain access to that signal.

Sure, but if he's having trouble finding a modern TV with a tuner that
"likes" the TS1000 (most modern TVs don't), then using clip leads to grab
the signal would at least verify functionality of the computer. Bearing in
mind that the TS1000 has been described as "common as cockroaches" (Sellam
Ismael) and "an educational toy" (Richard Erlacher), plus the fact that the
ZX81 was originally sold as a kit and zillions of them were assembled by
schoolchildren, I think my advice was reasonably appropriate.

Feeling grumpy today, Fred? ;>)
