looking for ideas...

I'm not sure if this is what you need but in my case with my old IBM PC
Server 320, that only had one LED connection, and I wanted to see activity
from both controllers ont he same LED, so I made a Y cable of the straight
rhu, but I put in diodes to prevent current flow from (say) controller 1
activity to the LED and pins of controller2. I only wanted flow one way, to
the led. I then removed that and went to a multi-color, multi-input LED that
blinked green for controller 1 and yellow for 2.

=> Ok, I know this is a bit off-topic, but I was looking for any
=> ideas as to
=> make a 3.5" or 5.25" drive bay LED array for my SCSI that I have
=> running.
=> Something that will allow for both SCSI controller LED's and then 3 or 4
=> LED's for HDD activity. Also, wondering if anyone knew how to
=> make an LED
=> that shows Ethernet connectivity and activity to interact with a
=> standard
=> ATX board and an old AMD PCNet II PCI Ethernet card.
=> The whole reason I am interested in doing this is that now that I am
=> running more than one machine tucked under my desk, I'd like to
=> be able to
=> see if something is wrong without having to open the damned
=> thing or going
=> desk diving for a failed NIC. Yes, it sounds lazy, but the idea
=> of a front
=> panel diagnostic isn't so bad and could also be used for other machines,
=> correct? Besides, lots of blinky lights always impress company
=> when people
=> or clientele come over, grin. So again, any ideas?
