I believe the earlier ones were soldered right to the boards, my 87 had a 24 pin receptacle the chip just pushed into. Ingo (who BTW did a FANTASTIC job, and quick!) just installed a 28 pin plug and stock program 28 pin chip in my DME and I have a 24 pin Autothority chip I want to give to someone. Obviously if he has a soldered on chip it wouldn't be worth it to de-solder/re-solder in this one as it's questionable if it will give him an improvement or not and going back to stock would be a PITA. Also, almost silly to have a 24 pin receptacle soldered in but certainly is one way to go for future upgradeability (though the 28 pin supposedly offers more programmability according to Ingo).. Soooo, anyone with an 84 chip it, and was it soldered?
