    Just a quick question about PC hardware, if you need a motherboard that still has a std PCI slot for a 5 volt PCI card
    [Canopus card] do you have to specify the voltage or does it autodetect the voltage??

    I have a legacy PC using a Canopus card that is having hardware issues - the Canopus is about the only thing worth keeping.

    First - are you sure the Canopus is 5V only? How many keyslots are cut in the edge-connector?

    Second, few modern motherboard will support 5V at all - you will need to check the specs to see if your proposed motherboard will do 5V.

    yep - the Canopus card has to power a 5V 19" assembly for video - it is a DVREX professional installation worth about $5k

    Everything else in the PC is slow [Celeron 3 yo], hot/cluttered [the case] or custom [RAM] it gets put aside and kept for spares for a similar unit at another site.

    As I understand it the 5V is not a power thing, but a signalling thing. How many slots are cut in the edge connector?

    Thinking about this further, are you sure the PC 5V is powering the 19" rack unit? This seems unlikely - that rack unit should have its own power. I would expect that it is much more likely that the signalling interface between the rack and the Canopus to be standard TTL 5V, which is a different thing entirely!

    EDIT: I've now looked up DVREX and realize that the 19" module is a break-out box. I would have thought that the voltage is irrelevant here.
