The 12v I can then split 3 ways 2 to pc fans to cool the stepper drivers and toroidal transformer and the other to the BOB.

The new PC doesn't have a parallel port (Doh! was watching a 3.4ghz it sold bought a 2.93ghz I7 assumed would be same motherboard and isn't!)

but does have 1 original PCI slot (And the rest PCI-E) so bought this

Do I need a better adapter or will this be ok? The other adapters do seems to have more chips on them lol.

And the PC has a 8400GS 512 meg gfx card will this be enough to run fusion 360, looking around it should do but I'll have to turn shadows and some other effects off. This machine will only be used for CAM and controlling Betty (My name for the router) so don't want to spend any more than I have to on it. My home machine is my cad machine (Got a 760GTX in that, seems to power along fine).

Going to have to slum it with 4gb on the CAM machine for now but want to upgrade my machine to 16 or 32gb next month and then can rob the 8gb from that for the CAM machine.
Add on cards are hit and miss. Some work first time, some are a struggle, some never work.
