With alpha's attached, especially a Multia an alphaserver 1000A or two or more as1200's then the mouse freezes after 15 to 20 minutes and a little later the keyboard gets into autorepeat mode.
Attaching an external power supply to the Newstar didn't solve the problem.
No idea what causes this behaviour.
Simply, variations in how the KVM handles the signals. Most PS/2 KVMs have to 'dummy' the signal to the computer because PS/2 is not hot-pluggable on almost all systems. this means the signal has to be passed on from one device to the other and some KVMs do it better than others.
Video is a worse issue. Some KVMs attempt to resync or retransmit video and it royally screws with the signal from some systems.

At least on my RX2600 it's a big weird DB connector joined to a cable
that has like 3 DB9 serial connectors hanging off of it.

That would be the "M-cable", it's a splitter/break-out cable. It's only
available for
systems with the iLO/MP card present. That should be no problem though,
there
is still the serial port that should work as well.

If you have a MP card on a Integrity server (or workstation) and need _only_ the (local) console function, you can use a regular 25-pin null modem cable to access the console functions and of course the other MP functions as well. The 25-pin interface is wired so that the console uses the standard pins (2,3 and 7).
Of course you can use the LAN console functions provided with the MP card. In some cases only the MP serial interface will be accessible and usable.
The MP card is otherwise useful also. E.g. if the machine crashes, you'll be able to check the logs for what has happened or if the machine is completely jammed, you can reset it remotely.

By 'Bog Standard' do you mean any old HP consumer PC keyboard? might try my Logitech keyboard attached directly to it (not practical long term as it's my USB KVM keyboard on a USB KVM that's also very picky about keyboards, especially Apple ones!)
Yep, about six quid off epay.

You should get up earlier, I only posted that this morning :P
RE: keyboards, yeah, those trap exceptions sure are helpful messages. WTF!
I also get a couple of trap exceptions associated with the VMS-not-booting because-it-hates-my-graphical-console issue too. It's not so much the trap messages, it's the noise the machine makes sometimes. Sounds like it's in it's death-throws! It's only a keyboard error, calm down! :)
It was the first problem I had with my ZX6000, and it would have convinced me the machine was a dudd, had it not been for a single post on t'internet about the keyboard being wrong.
I must have fluked with the Belkin USB adapter and it worked fine from the get-go. It was only when I plugged the input into the wrong port (I think) it spat it's dummy out. When switched to the USB KVM I discovered it was prone to spitting it's dummy out on any occasion of not having the right keyboard. Testing has shown it's rather fussy, so yeah.
I bought a bog-standard HP keyboard after that, which works fine, and I also ended up getting an LK464, which is nice ;)

Not tried with KVMs, but am 100% sure that milage will vary considerably.
Yes. I am sure it will too. KVMs vary wildly. I have a 4-port Startech PS/2+VGA KVM that works flawlessly on SGIs but hates my Belklin PS/2 to USB adapters. I have a Compaq PS/2+VGA KVM that hates SGIs bourt works fine with the Belkin USB adapters, and I have a Startech DVI+USB KVM that works fine with a Logitech Keyboard and Mouse but the USB kept disconnecting when I use a Microsoft Mouse and Apple Keyboard. Ahh... aren't 'standards' great ;)
Anyhoo - it seems to tolerate the Belkin USB KVM adapter for now so I'll go with that.

I hooked it up to my DVI/USB KVM and it freaked out on boot stopping and listing a couple of trap exceptions. It won't even get into EFI. I don't have a console hooked to the serial so I dunno if it's just disabling the video console due to the lack of keyboard (not detected or faulting) and falling back to serial - a lot of workstations do that. Unplug the USB and it POSTs fine and loads the book menu so I somewhat suspect it's not.
I also tried an Apple USB keyboard (I know I shouldn't let Apple stuff near real computers :P) and it did the same freaking out during POST thing.
anyone know why this is - is it just picky or am I missing a trick somewhere.
Woha!

Your point about the limited amount of storage space is what surprises many people.
In a way it also makes a (tiny) bit of sense, especially as the bigger players usually
tend to boot off SAN and larger, centralized, disk systems anyway.
