[TUHS] System III - TCP/IP

[lehmann@ans-netz.de (Oliver Lehmann)]

Hi Cornelius,

the system is more or less a clone of the Zilog System 8000 which ran ZEUS.
The clone was made in the eastern part of germany behind the iron curtain.
The 16Bit part of the system is more or less a 1:1 clone of the System 8000
and so is the OS also a clone of ZEUS (with modified part of the kernel to
adress the differences in hardware). If you are more interested about the
system itself, feel free to read more on my page (page itself is english,
but most linked documents are in german)

Regards,
Oliver
