So look at a Brazilian Prototype:

Kind of makes me wish I understood Portuguese better. :-) I can
make out the gist of it from my very limited Spanish, though.
It is a prototype of a pre-Ethernet network card for the Apple II. I
don't think it is related to the game server at all. though even earlier
networks were similar.
If I remember correctly, Amplus always used red coaxial cables to
distinguish themselves from the competition who all used black. I don't
remember them selling Apple II boards, only for PCs. Perhaps this
prototype never reached the product stage?
Alexandre, about the 188 processor: it was just an 8088 with some
peripherals built in (like the iAPX186 was the 8086 with the same
devices). Unfortunately, this chip was designed before the IBM PC became
important so it used different addresses for the same funcionas (timers,
dmas, interrupt controllers). You could build a DOS machine with this,
but not a PC clone so it didn't last very long in the market. If this
board has a reasonable amount of memory, then it actually is a more
powerful computer than its Apple II host.
