I mean seriously, every "smart"phone is now much faster than anything scientists had till the 1980s... yet since you are unable to write programs for it without the need of other computers, you cannot do anything they did.
On the other hand, if you had a "digital television set" in the 1980s, yes those existed, you had a device with much more processing power than the computer you could have on your desk. The problem was that your TV-set had it in hard wired circuits while your PC didn't even have the IO capacity to get the video signal in. (Digital TVs in the 1980s used digital chips to process the analogue signal, so they would digitize your PAL signal, typically with 7 Bits, and then decode PAL in the digital domain, which can bring you much better pictures at improved reliability and eventually decreased cost)
The power of a computer lies in it's capability to be programmed. If you cannot reprogram a computer, it's no more useful than any single function device.
