No. I meant one 40Pin Wide ZIF - which I see further you understood. And as for your forthcoming idea.... we must be totally in sync. I just spent an hour training my kid's soccer team (yes, with a broken leg) and came up with this EXACT idea. I pictured just the edge connector. I think they come in 2 x 40 Pin wide don't they? > The only downside I see to all this is that the oscillator pin connections > are getting rather long: PIC -> ZIF -> personality socket -> personality > card -> OSC connector -> OSC module -> crystal or whatever.

Can we have a combined "personality/oscillator" modules? Only one question at this stage. What do we do with the SIP connector when not in use? Do we need to isolate it at all? The rest of the list is awkwardly quiet! :-) Regards, Sean -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
