That made we wonder... what's the oldest *operational* digital machine owned
by anyone on this list? Although I suppose it's hard to define 'machine' -
something with RAM, I/O in some form, and at least one CPU (what the heck do
you call a CPU when it's no longer central?)
Some 'earlies' from my collection :
HP9830 (1973), desktop computer running BASIC from ROM
Philips P850 (1970), minicomputer with core memory
HP9100B (1969) programamble scientific calculator
Casio AL1000 (1967?) very simple progammable calculator
The first 2 use TTL chips, the last 2 are all discretes.

One thing
I love about my old IBM PC 5150 with ST-225 is that *it is still
running 22 years later*. I fire it up at least once a week to do some hobby
Newcommer :-). My 32-year-old HP9830 still fires up.
