        Aha! I had forgotten those. Weren't those the ones where the
CPU trays plugged into the back, and the RAM boards plugged into the
front?

        Of course -- a mountain of memory then is a drop in the bucket,
even for the Ultra-2 machines (my current fastest machines).

        It might be so. It has been some years since those were some of
the machines in the machine room at work. I no longer have access to
them, though I do have a couple of the desktop ones -- one S4000, and
one S4000DX, IIRC. The DX was for a while the fastest machine that I
had at home.

        I remember replacing the fuse in Sun machines which had suffered
the indignity of having a Solbourne keyboard plugged into them -- back
when the Suns had a bi-pin fuse on each system board for the purpose. I
don't remember a failure from going the other way -- but perhaps nobody
ever left the Sun keyboard connected to a Solbourne long enough. The
fuse was, of course, instantaneous. :-)

        ttya and ttyb were of course ZS ports -- even as far back as the
Sun 2/120. IIRC, zs0 and zs1 were the keyboard and mouse, and zs2 and
zs3 were the tty ports.

        Enjoy,
