The most commonly found data sheet for the HD44103 lcd driver chip on the lcd pcb is pretty low quality and doesn't include a pinout for the QFP-44 package used in the M100.
I extracted a nicer version of the data sheet from a larger combined pdf (Hitachi-LCD.pdf) that had sheets for several related chips, and worked out the pinout from looking at the m100 service manual, and found an editable SVG template for qfp-44 and assembled a new pdf for hd44103 with the nice clean main data sheet and with a page inserted for the qfp-44 diagram. The rest of the datasheet still refers to only the FP-60 pin numbers, but you can ignore the pin numbers and just use the signal names VCC, X1, V1, etc... I extracted a nicer pdf for HD44012 also, but that didn't need any additions or changes. It's just a clearer version of the same info. It might be a little more complete. The source document Hitachi-LCD.pdf seems to be a later version than the scanned fax looking version that you find on most datasheet sites. https://drive.google.com/open? id=13ITleFmcEjuzxSp1kvVipo__T1ec2KmT -- bkw
