Congratulations, Tony!
Hi Lee,
Thank you so much for your reply and kind words. It was a real rookie mistake Lee. Not only new to this connector but new to the type of flux I got from ebay a few months ago too. It was a fresh batch of NO-clean flux I just got. I should have realized it being so thick. These molex connectors are the ones you recommended (the 10-pin Molex 22-18-2101) that I got from Mouser. They must have had them on the shelf for a long time, because when I was soldering them they had a real problem sticking to the solder. From the top I tried a swipe of Noclean Kester flux and I am sure they dripped down into the connector during the somewhat long solder application for each pin. The tin plated pins must have gotten old. Never had this issue with really any other type I have used like this but who knows, Ill be care full next time, I still have to build the 1802 MC too.
After your reply today I went to the lab and probably used an 1/8th can of defluxer to clean the inards..again. Yup as you can see below I have a properly seated Z80MC! Man this is cool. I need to really purchase a nice ultra-sonic cleaner or something someday. One thing is for sure, Ill never have a flux buildup in these boards eventually. haha!
I love the work that went into this, both the hardware and software. Just awesome!
