Everybody said that in 1986 home computers were widespread., so audio CDs. Actually I had my first PC in 1986, was a Sinclair QL. No modem until the '90s actually. At school we used a bunh of Olivetti M24 and a newfangled Olivetti M28 with their almost-XP or AT compatible architecture
I think that having to use an '80s computer could be really interesting as a learning experience. On that times to make something useful you have had to leanrd how a computer works and all of the quirks of the system you were using.
And for television. I stilll have only CRT tv sets, hooked to a dvb set top box.
