Hi Marcel,
Based on your excellent blog post about the (S)GC boot process
(https://www.kilgus.net/2018/11/14/supergoldcard-boot-sequence/), I
managed to write a boot loader for custom QL ROMs using a (Super)Gold
Card. Turned out that the lower 48K RAM of the (S)GC isn't as
write-protected as we thought! This way you can change ROMs on the QL
without even having to open the case. Of course, this will need a (S)GC
unlike your solution and it provides no mass storage. I still like the
idea of QL-SD as floppies are too limited and getting unreliable as they
age, and using a Q68 as QLnet file server is quite slow.
The code for the boot loader is on my GitHub page:

Cheers, Jan.
