Can anybody tell me what an Extender Board is ?
It has part number 5012447D (with behind it also the text W9042).
It also comes with two 70-11411-1D cables but I dont know if they belong
with this.
Thanks!
Stefan.

I believe it's an extender board used with a PDP-11/34 FP11-A
Floating Point unit, but I don't really know anything else about it or if
it can be used for other purposes.

This is an extender board for testing an 11/34A floating point processor. You
put the FP Processor (FP11-A,M8267) on an extender board, connect the W9042
to the CPU, use the over-the-top connector between the W9042 and the FP11-A
and you have the only practical way to test an FP11-A on an extender board!!!
You have a great find. They are fairly rare.

Is it one of these?

If so, I gather it is an extender board used to help bring an FP-11A out to
where you can debug it.
Here's an FP-11A:

So I assume it has something to do with the connectors on the top of it.
Sorry I can't help more, but I'm not much of an expert on PDP-11s (though I
do have an 11/34A I haven't done anything with yet...).

That indeed is one (that I purchased ;-)

Yup, spot on. The text on the back is a little different but the board
itself and also the cables look 100% identical!!
Thanks for the help guys!!
If anybody is interested in it btw, let me know, willing to swap or
something (since I don't have any DEC machines anymore).
