Quote from: Benedikt on Yesterday at 20:22And is there any way to just read a specific sector in a file system agnostic way using Basic and to run it as machine code?The only way from BASIC is |CPM which loads track 0, side 0 sector &41. It will only load 512 bytes though (whatever is booted is then expected to load the rest).
Putting a write-protected system file in a known sequence of sectors is solved problem.
The question is about bootstrapping, i.e a DOS with the relevant capabilities is not already running.

Correct The WR and RD signals should be gated.
