PCI Riser Design Rework of GitHub PCIe Riser - Howto?

[Trash80toG4]

Your cable kludge worked without these? Are they present on other 2 slot risers?

Yep, no capicitors involved, just the resistor. Using jumper wires attached to all the requisite points I got:

Slot A = A1
Slot B = B1
Slot C = D1
Slot E = E1 - with signals jumpered from CSII Slot. This one's tangential, but I'll do a dedicated post here with the info/pic.

Can't you just flip it around horizontally?

Nope, it's mirror imaged in some bits.

Can you get component values from the Slot A schematic?

Gotta go walk a nature trail to reset fershimmeled brain!

Can you get component values from the Slot A schematic?

Yeah, 0.01µF seems right.
Are the purple pins on the illustration all GND?

 

[Trash80toG4]

None of the pins on the earlier diagrams are correct. I'm in the process of
- mirroring the connector so it looks like the component side.
- rotating the pin numbers
- rotating the signals so they match the proper pins - recreating baseline PCI pinout
- color coding the thruholes

Purple indicates the pins missing due to the break in the connector, they're all wrong . . . they belong at the high numbered end of things.
- Green = GND
- Red = Power of various values

IOW, hold off on schematic development until I get everything looking like the component side, numbers and signals tagged and color coded correctly.


So it goes . . .
