That is why I added a second socket to clear these two capacitors' "heads" and accepting the 32 pins ZIF socket onto the second socket's position.

It is useful whenever the ROM's content is seriously corrupted and can't be roll back to the original.

Where did you buy your ZIF socket ?
I think it is hard to find with precision contacts that match directly into precision sockets.
I made one hand-soldered to such a socket - not very nice looking.

Pokemon,

I ordered the ZIF socket from a Mouser Electronics( Mansfield, Texas, USA). Their website is http://www.mouse.com/.

Are the contacts round or square ?
My sockets here have rectangular pins and do not fit into these precision sockets with round contacts.

Good news, the Aries ZIF socket's contact shapes are round! :D I don't have to struggle installing the ZIP socket onto the regular precision sockets. :lol: Is that bluish green colored ZIF socket in that recent picture of yours a 3M brand or whatever?

I bought some (probably not 3m just chinese knockoffs) from Ebay that had rectangular pins and tried twisting to fit in dip socket...but they warped the sleeves where the chip inserts.

Didn't want to use ZIP pinned socket because I wanted to put DIP in case I wanted to remove ZIF.

Not sure what to do to cover either basis. Do round pins work in DIP sockets?

Gammaray,

Are these sockets, which you bought from the Ebay, green? Does these sockets have its 3M brand labels?

I have not tested an Aries socket with its round pins in DIP socket.

Thanks,
Dessony

The cheap textool and 3M clone sockets that you can get from China have rectangular pins and are impossible to fit into a turned pin socket. But if you apply a bit of force, they will push into a stamped pin socket. And then the stamped pin socket should fit in a turned pin socket.

It's a Textool. I prefer the model with round pins then and will buy one from next Mouser order.
I have another from Connfly which has same rectangular pins.

Correct mine are probably Chiner's... they are arranged like:

||||||||||||||||||||

||||||||||||||||||||

not what they need to be for a DIP

Was using them for an upgrade to SDK-85 knockoff edu' boards.

I probably need to use a header and solder an ugly "fix".
