EthernetTwo "ET" card for Apple2 by Babar de Saint Cyr.

This archive include:

ET.recto.jpg   a jpeg photo of ET card viewable by jpeGS
ET.verso.jpg   a jpeg photo of ET card viewable by jpeGS
schematics     a $C0 standard GS image file
readme         a doc file (you read it now)
snif           a sniffer program for ET card with source

ET card is built around  CS8900A Ethernet controler
(http://www.crystal.com).
Since this chip and peripheral componants are very hard to find in
France
I used a kit sell by Gary
(http://www.vermontlife.com/gary/crystal.html).
Cost is $60 for a kit and $120 for a full assembled and tested module.
It took me two hours to mount kit. Beginners MUST choose assembled
module ;-)
Then I used a prototype Apple2 card to install kit , 74245 and 74139.
Worked at first time!


To do:

a GSOS driver (including ARP management)
interrupt management
an hardware enhancement to follow Apple IRQ chain management
an hardware enhancement to bufferize address bus

Thanks to the three persons wich answer to me on
comp.sys.apple2.programmer:
Peter Schranz, David Empson and Jean Marie Friedt.
