Re: non-socketed CPU

Yes, I understand. I hoped to find a way to make the current STE booster work. But all remaining options sound too risky and maybe it's not worth it. Maybe someone else has some good ideas to add, and in the meantime my STE remains stock. Thanks a lot nevertheless for all the input, and at least I n...

Re: non-socketed CPU

I think the easiest way would be to fit a SMT socket. Assuming they align with the pads on the motherboard that is. Okay, this I could do. But then what? Use your adapter to solder a PLCC plug on the booster? Or could I use the same technique like you on your new plugin design? Mostly I have just b...

Re: non-socketed CPU

Yep, you're right. It's called SPGA, correct? And with that, all converters and adapters are out of the race. I could not even find a PLCC68 Socket with SPGA pinout.

So if I see this right, the only remaining option is ribbon cable, or did I miss something?

Re: non-socketed CPU

Ah okay, now I get it. Pins from your booster into the socket and the plastic dummy to clamp them in place.

Meanwhile I found this:

Re: non-socketed CPU

Exxos, in your post about the STE V1.5 booster you mentioned a "simple adapter". Is this already reality and if yes how does it look like? Could it be of any use here?

Or do I really have to resort to ribbon cable? :-P

Re: non-socketed CPU

Oh yes, now that I look at a picture of your booster, I see the problem... All PLCC plugs have their Pins layout in a straight line, and not like the PGA socket in an offset way. Damn...

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 :-P) I'm q...

Re: non-socketed CPU

Not sure what you mean by "PLCC68 Dummy" ? You mean like the adapter your posted before ? 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 ...

Re: non-socketed CPU

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 bo...

non-socketed CPU

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: cpu_no_socket.jpg My working route was desoldering the CPU and placing a PLCC68 Socket instead, then plug the new B...
