First of all, the clockport does not have a "Pin 1". This is because the part of the clockport connector, that would have this pin, is usually not populated.

Note that the GND and Vcc pins are nearly symmetrical on both ends of the connector.
The pin on the Subway with an arrow is GND, and as there is a transistor
close to this end, I assume this pin is 19 (the transistor is used for the
INT6 line).
Now on Kickflash you should be able to trace the corresponding INT6 line
directly to the zorro connector. Either that or check for _RTC_CS probably
not connected. I *assume* that _RTC_CS is close to the 42 on the left hand
side (bottom view), as the other side looks like the 8 bit data bus.
I would guess the Pin 20/19 is on the right hand side of the top view
picture. This means that the subway should be connected with the arrow pin
on the right hand side of the cable (or closer to the middle than to the
outside of the kickflash board).
This is only a guess. I went to the same hell when connecting a MP3@64 on
my highway...
Good luck. Don't blame me, if this stuff is wrong. Ask Jens and Michael for
safe information
