" Perhaps part of it is that it's so trivial to add that "little
" hardware" yourself? Two ICL232s, some caps, and a 7404, and you have
" yourself two more serial ports (TXD/RXD only, but that's enough for
" lots of applications). (Cf. NetBSD/sun3 config file FOUR_TTYS....)
if it's so trivial for us to add it, how much more trivial for sun to
design it in, with full rs232?
i've seen some earlyish sun kit - vme iirc - that had -six- ttys --
and the serial kbd and mouse plugged into ttyc and ttyd.
digression: the alm boards just added more zs devices and i think
there were even sbus versions. certainly there was config in the
sunos 4.1.4 kernel for them.
