I personally wouldn't use Molex pins but that's just me. I'm building for myself and don't have to meet a price point so I spend the extra money for the good stuff - in this case machined pins made for this purpose. Those Molex pins fall into the "cheap stamped pins" I was referring to above. Sure they'll work but for how long before they start having issues?

EDIT: Look at the piece those Molex are designed to mate with. It's not just a "stiff wire" like a tube pin. It's slotted to make it "compressible", and that matters.

Look into it later when the dust is clearing off the crater.

Thanks for your ideas, guys. That give me lots to think about. I'll do some experimenting and see what works best!

I was talking to Manuel (of nwts fame) and he gave me his experience with various pins he has used, also for IN-1.

He uses Mill-Max 0390. (Part number 0390-0-15-01-08-27-10-0):





The price from Mouser is around $0.42 each in quantites of 1000. For a 6 digit clock, you'll need 66, so that comes to $27 just for the sockets. Gulp.

From the Nocrotec shop: www.nocrotec.com/shop/product_info.php/i...or-pin--2-36-mm.html these fit

If you get them from Nocrotec, they are €1.20 each, so that makes €80. Triple gulp.

Wow, I had forgotten how expensive those mill-max pins are. Years ago we used to sell white ceramic IN-1 sockets, along with the tubes. I can't remember where we originally sourced them, but I think it was a Chinese dealer. We've also used the stamped metal pins in kits without any problems, but the mill-max pins are much nicer.

If there are any brick-and-mortar electronics part stores in your area, you should check there first before subjecting yourself to an online parts distributor. About 10 years ago, I decided to swap the incandescent panel lamps in one of my old minicomputers with LED replacements. The lamps were 28V T1-3/4 midget flange, and I needed 63 of them. The normal incandescent lamps could be had for pennies apiece, but all of the major online parts dealers I checked wanted about $8.00 each for the LEDs, which would've added up to around $500 to replace all of the lamps. I decided to check one of the local electronics stores instead, and found the same parts for $0.40 apiece.

Of course, I couldn't get away with that now, as the store in question now price checks everything online before they'll sell it to you. I guess it's a good thing that I cleaned out their stock of $0.25 Intel 4004s, long before they implemented their price checking procedure. We made some impressive 4004 profits on eBay that year.
