I still have the basic 386 PC that was anon.poenet.fi (using BSD UNIX). The most horrible one I remember was the Zilog Z8000 system that was the UUCP and USENET (EUnet) backbone for Finland for a while. It ran a Zilog implementation of System III. Unfortunately they, just like everybody else, noticed the discrepancy between the TTY termio interface implementation and documentation, but unlike everybody else, they fixed the code, not the documentation. The Zilog TTY driver, in raw mode, would not wait for a certain number of bytes and a certain time before returning, but would return after a certain number of bytes *or* a timeout. My horror story is of running the Helsinki-Amsterdam (penet-mcvax) backbone connection on UUCP over X.25. If mcvax was slow, the tty driver would occasionally time out -- and return with 0 bytes, (that UUCP of course took as "line dropped"), and that transfer of a news or email batch would have to re-start - while paying for traffic per data packet. Bills got pretty expensive pretty fast. Julf
