I think most people (especially the new users with tape only machines) need a somehow fast storage and some ROM for utilities and some memory expansion.
Old and/or hardcore users need a floppy (they have a lot of disks which need to be copied to modern storage and/or they like the nostalgie of floppy drives ), but then with everything with possible, Turbo EXDOS (HD support), etc floppy emulator is also possible, just for fun

So I suggest one popular card with CF/512K Flash ROM/512k SRAM/Dallas RTC (with built in battery). This can be cheap because it isn't too complex.
And later all-in-one full extra deluxe solution for the hard core users.

Fine. I'll go back to the old path

I just bought on ebay from Hungary, one ExDOS card with the bridge and manual.
I am very happy about it .....

I'm not sure I understand correctly.
You cried in front of a monitor with happiness, whether your eyes are watering when you see such projects ?
With what exactly I exaggerated in pure EP project ?

It was a joke.

Fixed addressing. Decoder made on a single chip GAL.
In this version, I forgot about a few little things. I do not have far too many pics, because I have to refine the design.
This project is done in three days, because I was sorry to use the original FDD (serial number 607), which was barely saved.
For the time being attached pictures before and after renovation.

The new boxes are original, restored or made by you?
