Subject: RE: BBS software for the PDP 11
As for power, if you have a wife and/or kids, a PDP-11's power
consumption is not even above the noise floor in your electric bill.
(Unless your trying to do it with RA disks!!)

Out of curiosity how much power do these wee beasties consume?

The plate on the back of my 11/93 says 345 Watts. That's about a fifth what
your
wifes hair dryer draws. Or slightly more than 3 100 watt light bulbs (which
your
kids leave on all over the house all the time!!)
bill
The light bulbs maybe, but you also run things much higher than 350
watts from time to time. The hair drier is meaningless.
Most of the lights I leave on now are LED pulling 10 or less watts. The
entire population of light bulbs in my house left on now doesn't get to
100w anymore.
I have 2 dell 2950's that pull a large power bill. That is near your
345 watts each, and I am plotting to take them out and their
replacements are Intel NUC's @ 40w each, pretty much the same go power.
the 11/93 probably isn't running as much compute power as one core of
the 2950. Nor possibly a Raspberry Pi. Whatever you want to do to
convert $$ to radiant heat, I guess no one is stopping you. Running the
old stuff for fun even for extended periods is one thing, but a BBS has
possibly the mission to stay up. Depending on what the OP has in mind.
thanks
