always bothered me that this wasn't well labeled as to where the hell pin1 is..  I assume its on the bottom based on this photo.. since I just moved (and again neglected to take pictures before unplugging) just confirming that..and where pin1 on the index cable is

I think you're right Greg, I'll check one of the cards for you to be sure. I remember using a black Sharpie to color the pin 1 from connector to connector, particularly on those 20-pin cables.  Pretty sure pin 1 is on the 'bottom' for all connectors. Does the HFDC manual point this out anywhere?:  I don't recall.

My HFDC manual states the lower end of each connector is pin 1, when the card is upright in the PEB.

If you look at the photo, there is a number two showing. It generally follows on these devices that the connector on the other side corresponds to connector 1.

excellent point!  Now I really want to go look at a few cards to see  if they all have that '2' and if there is a '1' on the other side of any of them. :)

'll look at my two tonight, and I do remember that on a recent HFDC repair that, that HFDC, had this 2 on it.

All of the HFDCs that I have (3) have the 2 on them. They were bought at different times too, so multiple lots of the circuit cards had them.

I took pictures of two cards.  On the older revision card the '2' and '34' numbers are partially cut off.  This isn't consistent among the older cards I have on the bench.  It appears the final run (lighter green card, #41) cut off less of the edges on either side of the connector. The lighter green card style was problematic in that many of the boards had one or more shorted traces.  In many cases the mask was missing in spots on the adjacent traces. Spent many an hour staring at boards BITD, looking for shorts...

I may as well mention that I will be posting a few HFDCs for sale soon.  Just been bogged down by work and other things lately.

Mine look like the one with the 2 cut in half, like Insane One's lower picture.
