> B) This picture sure as hell looks like ordinary pins in ordinary holes... > https://www.dropbox.com/s/1p9tz1jgirbfaee/IMG_1601.JPG?dl=0 looks like, but they are the same Batten & Allen mounted without the side clip. That is because I found easier to route some signals on a 700 mil board. Using the pins with the side clips requires a narrower PCB, I have made both versions anyway. ============================================================ FWIW I use more flexible adapters from a different source, but Matthew d'Asaro has been supplying ROM adapters using those Batten & Allen pins (as well as the previous taller version) to the Commodore community for a number of years; last I heard he was still selling batches of 50 pins separately: http://www.dasarodesigns.com/product/batten-and-allen-ba3760-dill-leadframe-dip-pcb-edge-clip-pins/ Brian's post sounds like maybe he's run out of them. But I don't see what the big deal is; if width is an issue as it is in some Commodore models I can see their usefulness but otherwise what's the difference from 'normal' pins? How is height an issue? You can't get closer than flush with the PCB, and if you shop carefully some of the pins out there are either the same thickness or only slightly thicker than an IC pin. I use pins from component carriers in my System/Option combo ROMs; they're essentially gold-plated IC pins but unfortunately they've become hard to find (and more expensive) so if I get any more orders I'll probably use similar pins from TE. m
