XF551 PCB and SIO Port Mod

[pixelmischief]

I have been listening to you people belly-ache and bad-mouth the XF551 PCB for over a decade.  Waaaaaah, it's a shitty single-layer.  Waaaaaah, the pads lift too easy.  Waaaaah.  Well, I desoldered the SIO ports from my XF551 last night in order to replace them with header pins so I can reroute the ports for a case mod.  Let me just say...

 

Waaaaah, this thing sucks horrible.  Lifted two (2) pads; and that was WITH a Hakko desoldering gun.  Freaking aweful.  I'll have a waaaaaburger and wash it down with a Whineikin.

 

But on to business.  Does anyone know what the specification is for a pin row that will fit in the weird, diagonally oriented through-holes on the PCB for the SIO ports?

Did some research.  So, I guess I am looking for the "pitch" of the pin row?

Anyone?

Just a wild guess, but one tenth of an inch? 2.54 millimeters. Hold up the legs of an IC to the holes and does it match? That's it then. So that's not diagonally of course, you'll need some math there.

I measured 0.7" across 5 pitches on an SIO socket with a pair of digital calipers,  this is 0.14" or 3.556mm pitch.

 

I believe this pitch would allow placing on the diagonal for 0.1" pitch.
