[Coco] IP packets on my coco

Mon Jun 6 19:30:16 EDT 2016

Brett,

In anyone's case. The CoCo is what it is, a wonderful learning tool. Each uses it as they wish.

I want to take nothing away from your work as it is outstanding to accomplish what you have!

No worries Mark.  You bring up a perfectly valid point: Offloading the
duties of packet formulation, the oodles of checksums, etc very well could
be the most *usable* option.  And with feedback from the hardware folk, it
sounds as if there's plenty of real networking solutions.   Let me do more
experimentation and see just how good -or- bad native coco networking will
be, before we rush to a hardware solution. (my modified DW server is a fine
solution for now, hardware-wise)
