I like it so much I've been trying to give it a hard time. I set up
seven PCs on the network to PING it constantly (189 tasks in all)
and all it did was give my 10/100 ethernet switch a hard time. When
I last looked 148 of the 189 PING sessions had crashed but the Vic
is still ok.

Not very, it only covers the 8 bit I/O range so anything that needs
memory space or DMA etc. won't work. still that should allow you to
use some serial and parallel I/O and possibly some of the cheaper
SCSI cards (like the ones bundled with SCSI scanners).

I've had some thoughts on how to implement memory access, more
interrupts and possibly DMA but I won't get round to that for a while.

Cheers,
	Lee.
