Correct, it will run at https://datacenterlight.ch using 100% renewable energy. It the least I can do to offset the ~3 kW everything (z114 + dasd + everything else) will consume.
Given that it generates like 10k BTU/hr or something like that the drain on the datacenter is non-trivial, so I a running cost was to be expected.
As somebody who started out in the 80s with Apple II and C64 stuff the year before going to college, I always laughed at the old “Star Trek’ episode where the new computer has to tap into the main engine for power. After seeing your new bit of kit, that doesn’t sound so far fetched :-)
Have fun with this beast.
