Classic mac fun (and some questions) (continued...again...)

[Brian Lanning]

I was able to find some schematics for the special iifx terminator.
it was just a few extra filter caps.  I had planned to make one,  but
hadn't got to it yet.  I managed to find a real one first.

the iifx has a nubus ethernet card with a 10base2 and aui connector
but no rj45.  the tranceiver I have is too fat to fit into the slot in
the back of the machine.  so it can't reach the db15.

i've been meaning to setup a linux box so maybe i'll try the emulator
route with that.
