About 25 years ago, or thereabouts, I bethought me to start
collecting early domestic computers before they became rarer
than Roman relics (But I stopped when I realised that many
others were doing the same)
I ended up with, ISTR, 5 PETs, and also the associated
disk drives and printers, all for £20.
ie, when collecting, I'd offer a nominal £20 for
anthing and would walk away if a higher sum was sought.
What happened was that my wife used to work in a
hospital laboratory and when they were upgrading
from Commodore Pets to IBM PC machines, the Pets
were offered for sale, so I told my wife to
offer £20 for one of them, and back came the
message that my offer was insulting and they
were going to seek a commercial outfit to
take them.
Of course, nobody had the slightest interest
in any of them, and so I ended up with the
whole caboodle for my one £20! :-)
But just one Pet with its keyboard permanently
attached is unwieldy for the home environment
and so I passed them all on to a collector
of Commodores.
What was interesting about the Pets was their
origin in the time of minicomputers, and they
were built to the same mechanical standards,
with a metal frame inside the case, and a beefy
mains transformer.
