Yeah, I also saw they were out, and someone wanted me to build a HM. I am moving and decided to look at what I had available today, and stumbled on to the OKIs. I saw they have 10 in stock.Wow, wish you had posted this yesterday! Actually ordered one of those OKI-78SR-5/1.5-W36H-C from Mouser yesterday since they had a few in stock (shipping cost me more than the converter itself).
They were completely out of stock when I originally ordered all my other parts, so I had to order an OKI-78SR-5/1.5-W36-C. Had to de-solder the 90 degree header, and then solder a 3-pin straight header onto it. Still trust the correct part more than my homemade one though, so I'll just keep it for backup since I haven't built my HM yet.
Do you still have any of these that you'd like to get rid of? I could use one for my old HM. It stopped working years ago so I just control it with the web interface now but I'd sure buy one or two of those if you wanted to get rid of them! Thanks, Jay
