Hi,
In an attempt to cut down on the number of monitors, etc.
here, I dragged out an old KVM (which, unfortunately, seems
to have lost track of his wal wart!).
It doesn't take long to realize that this is a non-solution:
- keyboards are PS2, Sun, USB, ADB, etc.
- mice are PS2, Serial, Sun, USB, ADB, etc.
- video is Sun's 13W3, HD15, DEC's RGB, apple's DB15, etc.
Does anyone make a *truly* universal KVM (i.e. so that
I can mix and match all of these flavors)? And, how
outrageously priced is it?
Or, do I just have to get used to hiding "not in use"
mice, etc. out of the way?

there is a sun converter for the raritan and for
avocent that converts the keyboard and video.
it requires sun keyboard power tu run the logic, and
is rare on ebay.
there is a mac box from raritan that converts to
ps2, maybe there are other such solutions.
ADB does not ring a bell, so I guess I don't have
them.
The Dec Vax type video and keyboards, as well
as the funny HP's ones are pretty much in the
"hide the keyboard and mouse" class.
AIX boxes that I am keeping must have vga
adapters, and ps2, though they are not w/o problems.

SCSI may eventually get phased out in favor of Fiberchannel, but it's not
anywhere near "not available on the marketplace" yet.
Larger than 36GB or so capacity drives are still expensive, though.

Or a DE9 connector for a RS-232 serial port, or 100BaseTX port to connect to a
Lights-Out management controller (or service processor, or whatever you wanna
call it), which can act as the system's console, as well.
Older stuff with framebuffers generally were meant to be workstations, not
servers, anyways, for the most part.

I have one of the early Apex IP solutions, which puts a
PCI card in a cheap compaq running Win NT4, and you
export the desktop of the Win NT box when you have the
video viewer app up on on your screen. Not fine, because
the mouse motions have to be tranfered in via vnc, then
when you connect into the viewer application which views
the input from the PCI card that has quirks.
It's cute if you are on the box's desktop, but pretty
much sucked for much else.
I also had experience with a recent box with an integrated
system to do video / mouse / kb on one side (including
automagic USB on one usb B for both USB Mice and
keyboard) and it was better, but still quirky. If you boot
it up and don't change video mode it worked okay, but
was still not as good as VNC into a system.
I'd just like to see a vga card with an extra RJ45 on the
back and VNC and VGA db15 on the back, plus
a connector for the mouse and keyboard for the system.

VNC is "doable" but, again, you have to get *into* the
system to install it. Sitting on the video out would
be great because it would be *just* as noninvasive as
a KVM (though apparently many KVM's are buggy).
I'd just like to see a vga card with an extra RJ45

There are add-in cards that will give you serial access
to the IPL process. But, I don't think any that will
export the raw video "over the net".

Keyboards that are USB convert to PS2 with a gizmo
or rather, keyboards that are both usb and ps2 can operate as ps2 with a
gizmo. a pure usb keyboard cannot.
Also this does not help machines with no PS2 input port. Assuming your
KVM is switching PS2 you need usb->ps2->kvm->ps2->usb->host which will
not work with the included "gizmos". Now there likely are 3rd party
gizmos that are more expensive that do this conversion.
- mice are
PS2, Serial, Sun, USB, ADB, etc.
meece that are USB can go to PS2.

Cybex Commander series is as close as you'll get. The ones I've
worked with are a backplane with cards that attach to computers or
console or other KVM units. The computer-conected cards are jumperable
to the type of kbd/mouse/display that system expects, and they make
cables for SPARC (with 13W3 display), ADB/DB15, PS/2-HD15,
AT/serial/HD15, etc. I've not seen USB cables, but that doesn't mean
they don't exist. As an added bonus, they do sound if you buy the right
cables, and allow up to 4 user consoles per setup.
The newer ones are a lot smaller, support USB, and don't have the
mix-&-match backplane.
Fairly expensive, but common on eBay and the cables come up
reasonably cheap.

Yes indeed. I've seen a couple of them at RE-PC in Tukwila (Washington). They were
made by Cybex, and bear the name 'Commander.'
They consist of a mainframe which is configured for different system types through the
use of different plug-in modules. The cables are interesting in that they're all
high-density D-sub shell (D-25 sized, but about 70 or so pins) at the switch end, and the
other end fanned out into KV and M plugs appropriate for the system you were working with.
The mainframe itself accepted a standard PC keyboard and mouse (PS/2 style), and
electronically adapted it to drive whatever was plugged into the switch.
That's in the surplus arena. It is also my understanding that Raritan, Avocent
(formerly Apex) and others make current-production universal switches. However, most of
them seem to have price tags in the low four-figure range.
Happy hunting.

So far, not really. Granted, I have a nice Raritan that's OK, so
I've been accumulating Cybex pieces on the cheap. I've spent about $30
on what amounts to a fully poplulated chassis - 12 system cards and 2
console cards, and around $15 apiece for 2 SPARC cables with sound, a
very long console cable, a couple of standard PS/2 cables, and one
AT/serial cable for my BeBox.
And, yes. I have an Imperial crapload of money in my toys - Macs, an
Alpha, the BeBox, and RS/6000s mostly, and I simply don't have room for
the machines and separate HID. I don't mind spending $300-400 on
consolidation that gets me good graphics and, as a bonus, even switched
sound.
BTW, in answer to another question in a different post, the console

your Sun keyboard, mouse, and monitor.

As far as I know, from a cursory examination, there is nothing active about the cables.
They're just wire.
As for plugging the "wrong" cable into a card, I'm not sure if that would

Sun/PC/AppleDB15 are all just VGA with different packaging. I read the
manual for my Apple 15" Monitor, and it has a pinout in the back
describing that it was basically VGA on a different connectior.

Well, *all* video is basically just differences in connectors.
But, some connectors also encode information about the monitor
for the host (static or dynamic schemes). Some like to
put sync on separate pins -- others like SoG, etc.
And, having all these "adapter plugs" on the ends of cables
doesn't help signal quality -- nor does it make things any
*cheaper* or more reliable! :-(

Sun/PC/AppleDB15 are all just VGA with different packaging. I read the
manual for my Apple 15" Monitor, and it has a pinout in the back
describing that it was basically VGA on a different connectior.

Hi,
In an attempt to cut down on the number of monitors, etc.
here, I dragged out an old KVM (which, unfortunately, seems
to have lost track of his wal wart!).
It doesn't take long to realize that this is a non-solution:
- keyboards are PS2, Sun, USB, ADB, etc.
- mice are PS2, Serial, Sun, USB, ADB, etc.
- video is Sun's 13W3, HD15, DEC's RGB, apple's DB15, etc.
Does anyone make a *truly* universal KVM (i.e. so that
I can mix and match all of these flavors)? And, how
outrageously priced is it?
Or, do I just have to get used to hiding "not in use"
mice, etc. out of the way?
