Re: PiServer - Client OS installing error using apt

The PC running PiServer needs internet access - at least for first setup.

Try typing that command in the terminal:

You can emulate x86 using qEMU and run windows 95 but it's not exactly fast - maybe usable for some things.

XP was unusably slow when I tried.

You can order multiple RPI Zeroes with presoldered headers from modmypi ( 20x ) and pisupply (no limit ?)
but you pay an extra £4-5 each for that:

Pi Zero: £4.80 ... with headers £9.95
Pi Zero W: £9.60 ... with headers £13.99
