It starts with the assumption that the VM/370 machine will be virtual.

Ignoring the XT/370 and P/370, where there any other System/370 systems that could run on a 15 amp 220v/240v outlet? If not, it would be difficult to put into the living room, in most parts of the world.

"Most parts of the world" use 230V with sockets capable of delivering 16A. In the UK where the standard mains connector is rated at 13A, you'd probably need to do a bit of measuring but you'd be okay. If you really needed it, you'd just have a Ceeform connector run in and a 16A breaker - quite common in garages, especially if you've got workshop equipment to run.

About the only countries that don't use 230V are the US, Canada, and Japan, which even combined only have about one third of the population of India.

Add in Europe, Africa, the Middle East, Australia, and New Zealand, and you'd probably find that most parts of the world can cope 240V 15A no problem at all ;-)

The 3081 processor took 23kw

Which is like 100 amps at 230V so you would need several sockets to get that much power. Just getting the machine into the room looos like a challenge.
