Internal Microcontroler

[mf0hka]

Not sure if this is helpful or not, but on mine, the internal microconterler is a Freescale MC9S08JM32 chip. http://cache.freescale.com/files/microcontrollers/doc/data_sheet/MC9S08JM60.pdf

I have a steelseries Apex Gaming keyboard.

I doubt there is much else we can do with Apex keyboards that ApexCtl doesn't already do. So the internal microcontroller documentation while interesting may be not of much use, unless we wanted to rewrite keyboard's firmware.
