Howdy everyone this is my first time posting on here, need some help with finding the right riser card. This one is too tall for the case I'm using, it's for a Packard bell pb450m+ in a Packard bell case. I need a 3 slot version if anyone could recommend a part number or link to one I would appreciate it. Thank y'all for the help.

http://bitsavers.trailing-edge.com/components … ochure_1993.pdf shows 2 example riser configurations. You might be looking for a VLB riser? The missing chip is a PCI bridge for optional PCI riser.

That look about right but I'm not finding any online for sale in the three slot configuration

I took the one out of mine to get some pictures, it's a 3-slot one with a low profile LPX case:

The attachment pb450-riser1.jpg is no longer available

The attachment pb450-riser2.jpg is no longer available

The attachment pb450-riser3.jpg is no longer available

The letters in the top left of the back of the PCB seem like the best identifier.

Looking around thebay for isa risers, I spotted this one for sale in the UK:

The attachment p4500e-1.jpg is no longer available

The attachment p4500e-2.jpg is no longer available

It's a slightly different design, but the part code PB4500E is actually silkscreened on.
