Seeking Mega Macs 42 SE, 50 HDD, 55 CF-Card, 56 eMMC Dumps for Study

Greetings,

For educational purposes, I am looking for HDD dumps (42 SE and 50), CF-Card dumps (55), and eMMC dumps (56) of any Mega Macs device.

I'm aware of how hard these are to find in 2024, but maybe this is the right place to ask? :)

Thanks in advance.
