Question Converting CDM4/19 based player into top-loading

Hi everyone

Im converting Rotel-855 (CDM4/19) into a top-loading player and would want to remove the loading tray and the motor.

The question is:

Can anyone suggest a simple way of modifying existing schematics, so I could have one button to reset the CD reading?
I.e. one button controlled by the CD cover and being ON only when the cover is closed. Opening/closing the cover (button state: Off/On) would make the cd player re-read the CD.

Rotel uses MC68HC05 microcontroller for running the CD loading mechanism. I have service manual for R-855 and MC68HC05 datasheet if need be.

Any help would be highly appreciated.

Thanks

Good deal.
I would have chimed in but I know nothing about converting this to top loading.
Although I do have an RCD855
