I despise Windows 2000. Not as much as I despise Windows ME, though.

That's OK. I got VAXen. I even have an Alpha. Someday I'll properly
grok VMS.

Thanks to Douglas Gwyn by way of Henk Gooijen:

Click on the 11/35 console.
Click on the uPDP-11/93 link.
There is a simple page about the 11/93.
The only interesting part (?) is the
description if the DIP switches.

That _was_ a joke, meant to demonstrate my unbounded greed. :)
I was already negotiating a trade for some Qbus ethernet adapters; now
I just need one more.

Wow.

I have one somewhere, from a SparcStation, IIRC, that has a $2495.95
sticker on it. I have no idea if that's the price.

Well, I have an RRD42, and a much faster Toshiba that seems to be
DEC-friendly (Will successfully install OpenVMS). I was basically
asking if the M5977 supports a CD drive as a bootable device. As far as
which version I want of RT-11, I don't know. I've no idea which version
would be optimal.
Ahem. Naturally, I would never ask anyone to engage in possible
violations of Mentec's copyrights or license policies. Ahem.

Well, I'm not inclined to install Windows 98 right now. ;) But I
think that your suggestions could be duplicated/translated in Linux with
dd, cat and cdrecord.

Well, all I have to compare it with is an 11/53, and I haven't had
time to really put either machine through its hoops, so I'm pretty
openminded.
