Bill Cunningham:
I am copying all I can from the unix archive and will burn it to cd
because I know how precious they are. But what I was thinking was v5,6,7 for
example. Take them and add USB support. Linux would be a good example from
which to draw from. Because it's Posix. Much more could be adde to /dev.

Has anyone ever made a UNIBUS or Qbus USB card?

The problem isn't so much the hardware, it's the software. A USB stack
(OHCI/UHCI) isn't exactly small and I doubt you could create a driver
stack that would fit in a PDP-11's 16 bit address space (ie TCP/IP is a
stretch in that it only works on systems with 22-bit addressing and I'd
say that a USB stack is *at least* as complicated as a TCP/IP stack).

No, it certainly is possible. I've used USB stacks on much smaller
devices, such as Microchip PIC18. That is not a full-featured stack,
but certainly enough to do quite a lot.
TCP/IP doesn't have to be large either. See Adam Dunkel's uIP: http://
