Other stuff
===========

UMD laser flatcable
18 of 22 used. other 4 have pins allocated on the chip but no idea what they do

# Crystal oscillator 27 MHz
2700L
E52QA

# Crystal 4 MHz
[M] 4.00B

# Crystal 32.768 KHz
A507Y



That clockchip converts 27 MHz into:
* 36.83 MHz		?
* 22.58 MHz		?
* 27.00 MHz		?
* 48.00 MHz		USB
* ? MHz			?
Note... I don't know if my frequency counter got it correct since it only shows two digits before and after decimal point.
