Looked on ebay already?

Thanks for the link. That does appear to be what I'm looking for, but for about that same price($45 US shipped) I can buy a whole replacement 5x86 upgrade chip ($30). I was hoping to find the part for less than the cost of just replacing the CPU.

Just search for pga socket on the ebay of your country. There are some cheaper offerings from Hong Kong.

Wow, your TrinityWorks PowerStacker has twice as many DIP switches as mine!

You want to look for PGA 168. This one is cheapish. I bought from him before. https://www.ebay.de/itm/ECE-PGA168-SOCKETS-3- … CS/321163112146

Why don't you just solder on a new pin?

True. You might be able to salvage one from an ic socket for replacement so you could even get away without soldering if you can press out the old one.

Ooh, I used to have a TrinityWorks Powerstacker just like this. It was nice because it worked in almost every 486 socket I put it in, without any grief.
I hope you find a replacement pin for that thing, it's totally worth fixing.

Indeed ..you are very lucky it is a corner pin missing ..and imo worth replacing ..
Yoy might even get away with a comonent leg ..say off a resistor or capacitor solderd in and cut to size .
Though it wouldnt be as tigid so it may bend when inserting the chip.
Well worth trying a fix.

good luck

Where are you located? Pretty sure I have an extra one I can send you. Let me check at my office in the next day or so.

I know I won't help with it but... I just love this QFP 5x86 and I hope one day I find one (buying anything has been out of question during the last few years). Once I obtained one from an industrial CPU card but it was so messed up with epoxy(?) that I had to part with it. It would be much nicer to have one that actually fits a common Socket2/3 board anyway.

Thanks everyone for all the replies.

Interesting! Is yours a different revision?

Your eBay link is what I was looking for. I did find the US link for that listing, and it's looking like the cheapest option for me. I may try soldering on a new pin as others have suggested, and if that doesn't work, I will replace the riser socket.

Thank you for the kind offer! I'm located in New Jersey, USA.

I've got a really clean Gateway 4DX2-66V desktop that I'm looking forward using to play with this 5x86 and a newly acquired DX4-100 Overdrive. I have the original heatsink for the Trinity as well. I took it off many years ago when I was trying to identify this CPU.

It's such an interesting CPU. It's a shame that the one you found was messed up. I remember when I first found this chip, probably 15 years ago, and I was really surprised when I saw it rather than a more typical ceramic PGA 486.

Ha so funny I was born and raised in NJ and now live in Minnesota. I do have one I can send you, PM me you address and I’ll get it sent out.
