As my ROM-port is not free (MICE) and I have no Gold/SuperGoldCard I would
prefer solution D) (although I hope I am able to do the upgrade by myslef).
Solution A) would be o.k., too (then I would plug the interface to my Q40).
If I did misunderstood something and solution D) isn´t working

I would very much like to have one functional microdrive.

Not important for me. But would be *very* nice to have

Abandoning the microdrives completely is
with small capacities of several hundred sectors.
