MSTe (and STe?) PLCC socket type

Postby Fujiyama » Fri Aug 29, 2014 12:28 pm

I appear to have ordered the wrong 68 pin PLCC socket to replace a damaged one for the 68000 in my Mega STe as I wasn't aware of differing standards.
The new socket I have has a shorter spacing between the pin rows than that of my Mega STe PCB as well as a different layout. So what's the correct name/type of the correct socket?

Are you a good person?

I didn't know....

Maybe you can ask them: http://www.ebay.com/itm/2pcs-PLCC68-soc ... 20eb90aa04

Or better: www.mouser.com
Trying to learn...

After fruitless efforts finding one I eventually contacted Atari dealer Best electronics who had them for sale. Apparently these are custom made sockets or something. I wonder why Atari in their wisdom decided to use specialized components when standard ones with the same pinout were available...

EDIT: I did contact Mouser electronics about it but they had never seen such a socket and couldn't help.
Best electronics told me that the non-standard staggered footprint 68 and 84 pin PLCC sockets were used in various STs. Fortunately they have them, but beats me who made/makes them. If anyone knows, please chime in!

Contact Best electronics to ask if they still have them.
I've been unable to locate them elsewhere and I'm guessing these were custom made for Atari (reasons unknown to me).

This issue was discussed in this earlier thread, with clear pictures of the right and wrong types on the second page of the thread.

viewtopic.php?f=15&t=27504&p=267313#p267313

I ended up ordering from Best Electronics (California), apparently the only source in the whole world for direct drop-in replacement sockets like the Atari originals. At the point of sale they weren't badly priced, about $7 for the 68-pin and $8 for the larger 84 pin ones... but by the time I dealt with the minimum order value, minimum order value accepted via Paypal (which was more) and carriage from the USA to the UK the price in real terms was eye watering. I had to order a lot of stuff I didn't really need right then in order to make up the Minimum Order Value, which of course increased the carriage costs.

It's the only criticism I have of Best Electronics, who are otherwise a fantastic Atari resource.

I ordered them anyway because the original sockets were definitely faulty.

At the time, Exxos's socket converters were just a twinkle in his eye otherwise I would have gone (and would certainly advise anyone in the UK to go) that way instead.
