I think some measurement is called for...
5kwh a day to me sounds like a 1960s rack mounted minicomputer. A 1984 ibm pc xt i would guess would be more like one ampere/120v (US) or 100 wh. Monitor might be the same consumption.
A modern laptop is 1 to 10 wh range.
I could not find a line power ampere rating online, easily, and i don't have one to measure with my Kill-A-watt.
Right! Sorry, I was reading "5KWh" as ongoing rate, not daily sum. You are of course correct.
@mntmn yeah they can be slow af. I was just wondering about it cause a serial modem is something you can just wip up on a protoboard and is easier to experiment with to test a concept. I think I can build one, but I could never build an internal expansion card, haven't put any points into that skill :3
Might attempt to build the serial version and test it with my eMate 300 =^.^=
