Hi Corey,<br><br>
Check the pinout of your keyboard encoder with this site: http://www.xs4all.nl/~ganswijk/chipdir/giicm/8048.txt I bet the Xtal is on pins 1 & 2, plus the +5 and Gnd will also be correct....also that the RESET pin on the plug (center pin of the five) goes directly to pin 4 on the IC...if not then check the 8051...<br>

</a>Almost every keyboard that I have seen since the old Apple II's has used a 8048, 8051, or variation of same. <br><br>

Anyway, it has a few interesting things. The board is denoted with a<br>
