DIP socket for thee WDC 65c02?

[LIV2]

Hi All

I'm working on my first 6502 project, just wondering what the row pitch is supposed to be on these?
I bought a DIP-40 socket with a row pitch of 15.24mm but when I tried putting the processor in, it was an extremely tight fit and hard to get back out again without damaging anything.

Am I missing something? I can see that there are slightly larger sockets available in the range of 15.49mm or so but they're pretty expensive in comparison.

Welcome. Row spacing is .600", which is 15.24mm; but the pins on new DIPs are flared out slightly for the machines that do automatic insertion in PCB assembly. When you assemble by hand, the normal thing to do is stand the IC on its side on the workbench and bend the pins so they are 90° to the larger surfaces of the IC.

Awesome, thanks!

Also, the fit into a socket is intentionally tight to assure solid connections. You are trying to unplug 40 pins, so expect it to be a little difficult. I use a letter-opener of all things for removing DIP packages from their sockets.

Yeah, those dedicated "IC extraction tools" are useless. I tend to use just the right size flat edge screwdriver. Wiggle at both ends and out she pops. Much better then the "over the top" extraction tools you see available.

I must confess to ruining a few ICs in my time by being cack handed.

The letter opener works well because its tip is slightly bent, which means I can get it under the end of the chip and still have the handle angled upward above adjacent chips. Been using it for some 30 years.
