[En-Nut-Discussion] Vintage Ethernut 1.1 documentation

[Hugo Simon]

Hi,

I have an vintage 1.1 Ethernut, that one with the mega103 processor. And
I've lost my hardware documentation. Does anyone have this old stuff?

I have two questions regarding this:

1. is it possible to change the processor to an mega128, inkluding faster
crystal
2. is there any possibility to add an memorymapped (2kB address space) addon
board

The sense in this is to exchange a Z80 CPU with the Ethernut in my DS9-table
(www.trektech.de) which is broken. It lost its flash memory content and my
old Eprommer also does not work anymore.

So I thought adding a nut is a good idea, so I got ethernet that way and the
old nut laying around senselessly. My first attempt doing all the stuff in
software was a mess, both nuts (the old and a new 2.1 are much to slow for
that).

Thank you
Thorsten
