Isn't using a PDP-11 as perhipheral processor for a ZX81
a bit out of scope ?

what about a water flow sensor which tells the amout of
water used at the sink, and a soap dispenser switch to
see if soap has been at least requested ? So if one doesn't
use enough water, or over a way to short time, or didn't
use soap at all, or triggered the soapswitch without using
water afterwards, we just keep the door locked. Maybe with
an additional voice output according to the situation (*).

door, a message like 'The sanitary sywstem of this UDP
facility would apreciate if you also cleanthe door handle'
should be added.
