Hi, On a perfboard prototype I'm working on, I'm having startup problems. Of my bag of 16C74A/JW chips, only one or two of them like to work. If I put in a real low-speed crystal instead of the 20MHz it's supposed to run at, I can sometimes coax it to run. Putting a scope on the crystal pins verifies that the oscillator is running, but I suspect it's burping or slow getting up to speed or something. This perfboard nightmare has a ZIF socket on it, so the whole thing is less than a favorable environment. I recall seeing a thread with similar woes, but don't remember if anyone came up with a solution. Any takers? I've messed with caps, series resistors, etc, with no real success. Sure slows things down to only have 1 or 2 chips to work with. Thanks in advance, Bob
