Wow! I have a drum-machine with a sequencer operating that way, but no counter.
Having seen Zuse Z3 in action brings you perspective. :)
22 bit floating point in relays. :)
Let's see if we can't get something similar out of DCL. Now where's that bag of
1N4148 I bought a few years back! :)

IR yes - some, bring your palm up and feel the heat. But the tubes inside is
better at it.
X-ray - no much really. Too low voltage (150 V?) to really become a hazard.
Those TV-tubes you smashed as a kid was running as high as 25 kV and that is
the normal limit, but the thick glas is there for a reason.
If the mice dies around the house, suspect the neighbor cat of not doing its
job propperly, if they only disappear be happy about him or her not being THAT
lazy. :)
Cheers,
Magnus
