I have never seen one (and I have plenty of printsets from back in the day).

I'd love to see one to verify differences between the 4Kbit and
16Kbit-stuffed boards.  I'd consider taking one of my 16K boards and
turning it into 128K (easier desoldering than by unpopulating a 32K
board)

The frontpanels for PDP-8/e/f/m are pretty obvious when seen on a pile
(and aren't seen on piles that often), but I agree that the
programmer's panel for the -8/a is something to look out for - I have
one ($50 a couple of years back), and would recommend them for anyone
who wants to do more than just hit a boot switch and fire up OS/8. 
For the uninitiated, it plugs into the "standard" I/O board, the
DKC8AA, via two 40-pin cables.  Pretty much any OS/8-running or
WPS-running -8/a I've ever seen, has a DKC8AA.  It wasn't _required_,
but it was ordinary.
