The great thing about these machines, actually, is that .. you can always find a new user for an old machine.
The 8-bit systems of today would give the 8-bit users of the decades past, positive conniptions at the mere concept that there are, pretty much every week or so, new releases for these ‘’ancient’’ systems ..
Actually, kids learning computers these days -definitely need to know more about ancient computers- as a positively directed purpose.
So, if you’ve got someone in your life who has the interest, all I can say is - crank out the old machine, turn it on, and do something fun/useful with it.
