I disappeared for a while, but 2017 was very busy for me. Unfortunately, the effects of this work are hardly visible.
I spent a lot of time on repairing retro computers. Mainly ZX Spectrum.
I also lost a lot of time for the remake of the Italian Chrome 128 project.
It caused a lot of problems, and even though the clone works, I'm not happy with the result.
I wanted to squeeze out more of it.

So it's time to go back to my own projects.
Because in the last year quite a lot has happened in the equipment for EP (internal RAM, SD card reader), I have revised my publishing plans.
Only two projects will remain from the entire package of cards I have planned so far:
* Dream Turbo Card (started) and
* AMIO Card (originally it was supposed to be AllMost In-One, now more Advanced Module IO ;) ).
It will be a compilation of previous projects.

The first one will be an internal module. It will feature:
* a programmable, two-channel clock for the system and EXDOS
* Real Time Clock
* 1 MB RAM memory (optional 2MB)
* FlashROM 512KB with programmable page mapping.

The second module will be external. It will contain:
* a diskette drive controller
* 3.5" diskette drive
* built-in Gotek-HxC
* CompactFlash card slot
* maybe ZX Spectrum 48K Emulator.

This is the plan and at the same time the New Year's resolution :)

As the turbo clocks are generated internally, how will you pass the clock signal to the WD on the Exdos controller? I think you will need an extra connector to not interfere with the system clock on the expansion connector.

The second clock I will want to move out on the external edge connector instead of existing 8MHz signal.

But then, it will interfere with other cards that need the stock 8Mhz clock.

Better ask Zozo if some of the Not/Connected pins of the expansion connector can be used.

In this case, only pins A34 or B34 remain on the edge connector.
What about the 1MHz signal? Is it also supposed to remain original?

No any card which is use it.
I suggested it this solution, because then not need to modify the EXDOS card for HD handling. (Only need WD 1772 PH 02-02 installed).
