I simply put 2 computers in 1 case WITH NO CONNECTION BETWEEN THEM.
One is for internet.
One is JUST FOR YOUR OWN WORK.
You can hand carry files on memory sticks from ONE SIDE OF THE CASE TO THE OTHER SIDE OF THE CASE.
BUT HAND CARRY IS THE ONLY WAY.
NO FIEND ON THE INTERNET CAN EVER ACCESS THE PRIVATE WORK FILES ON YOUR WORK SIDE OF THE CASE.
Today for just $10,000 in special security programs you can get a system inferior to the one I provided decades ago, for free.
