[HECnet] VMS on zx6000 - KVM thread

[hvlems at zonnet.nl]

My Newstar 4 port KVM switch (PS/2) also shows weird behaviour. It works flawlessly with 4 pc's attached (regular Compaq branded pc's). 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.

Something else I've noticed is it's REALLY picky about keyboards and KVMs. I currently have it hooked up to to a Compaq KVM via a Belkin PS/2 to USB adapter and that seems to work okay. It starts up fine and booted into Debian and such okay (although Xorg didn't work but I blame that squarely on Xorg mis-detecting graphics card). 

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.
