Hiya,
I just read that the new plug-in STE booster is not likely to be ready anytime soon. I was looking forward for this mainly because my STE has it's CPU SMT mount without a socket:
My working route was desoldering the CPU and placing a PLCC68 Socket instead, then plug the new Booster into that socket.
Since I am most likely not alone with that problem, I thought I made a topic out of it and see where it goes.
So the new idea is to still socket the CPU and then finding a PLCC plug which can be soldered onto the booster and plug safely in the new CPU socket:
Could that work? Has anyone tried that? Are there any experiences or alternatives? In addition, any recommendations for PLCC sockets and plugs?

Re: non-socketed CPU
Good topic.
It is indeed a problem, even so on STFM's as well. The only thing I have seen is the Amiga guys, basically gluing a upside down socket ontop of the CPU and running things that way.
Though as the CPU needs to be removed and replaced with a faster one, that solution wouldn't work, at least not for boosters anyway.
Maybe some SMT PLCC sockets which may fit ?

Re: non-socketed CPU
If you replace the CPU with a PLCC68 dummy, I believe it would work. But would this have any advantage over a PLCC Socket and -Plug combination?exxos wrote: ↑Tue Aug 22, 2017 2:35 pm It is indeed a problem, even so on STFM's as well.

Re: non-socketed CPU
Not sure what you mean by "PLCC68 Dummy" ? You mean like the adapter your posted before ?

Re: non-socketed CPU
No, a PLCC dummy is basically an empty chip casing, like these here:
http://www.topline.tv/plcc.html
You could replace the CPU on board with a dummy and then clip the reverse PLCC socket on top of it. The CPU would still be replaced since the dummy contains no logic.

Re: non-socketed CPU
Had not seen those before.
Oddly though, I did get a couple of plastic squares made which was basically the same thing (without the pins) to use as a dummy CPU for my "plug in STE booster". Its one thing to have the pins going into the socket, but nothing to really hold it all together, so a "dummy CPU" was needed. So I got some plastic squares cut for that.
In anycase, If going to the trouble of soldering a dummy CPU, That socket you posted could just be soldered instead. Or use a SMT PLCC68 socket. I guess which ever way is going to be a bugger to solder... Which most people wouldn't be able to do.
Can't really think of any other solutions, best fix, replace the motherboard

Re: non-socketed CPU
Only other solution would be to have a adapter PCB. With a PLCC socket on it, and maybe right angle pins out of the bottom to solder to the motherboard. IIRC the new PLCC68 sockets are a fraction smaller than the original ones, so it might "fit" together.

Re: non-socketed CPU
what exxos means is this http://www.ebay.fr/itm/SOCKET-PLCC-68-P ... xyd8NSa8Dd (just an example exxos, don't slap me)
If i take too long to reply, sorry my cat is sleeping on my laps.
Re: non-socketed CPU
Yep, I understand. My plan was to desolder the original CPU (I would have used hot air) and replace it with a standard PLCC SMT socket like in your link in any case. This way I would have a more or less "standard" STE board with a socketed CPU (If I did not mess up the CPU in the progress
) I'm quite positive this is doable.
What concerns me more is the other half of the project. Is it possible to solder a PLCC plug on the bottom of the STE booster? AFAIK it was planned to equip the next STE booster with a PLCC plug to circumvent the user having to solder anything. Could this plug be fitted on the current booster?

The booster I was working on is this one... https://www.exxosforum.co.uk/forum/viewt ... p?f=3&t=46
Though I planned not to use a socket at all on that design, just solder the CPU direct to the PCB. The pins would plug into the CPU socket on the motherboard... The pins would probably align to the motherboard where the CPU is soldered direct. Though still have the problem to solder the pins to the motherboard. No way to get the soldering iron to solder them direct. So only solution would likely be is to solder some sort of socket on the board.
