The most expensive part is the PIC chip (~ £10) here in Brazil (without shipping).

Oh, and the PCB.

Sorry guys, but this is the price !!! You seems forget that we are talking of homebrew hardware, made in very small batch (max 20/40 boards made in each batch), and not mass produced ! So yes the price is high, mainly because parts must buy in small quantities from some merchant like farnell, radiospare, digikey...

Here the bill of material of the first batch done in France in 2008:




If you found the price too high, it's easy: don't buy it, others will buy it ( 200 units sold by 4 differents people at 80 euros ! Incredible Isn't It ? ), but please avoid posting this kind of insulting message.

It looks overly complicated compared to my idea of using the host computers keyboard, mouse and video output to select disk images by use of a "default disk". A platform specific default disk image which contains a menu system which can read the DIR contents of the SD and allow selecting of disk images using nothing more than the floppy disk cable and one button (which could be the eject).

You have to like the OSD (On Screen Display), That function could easily be included into an external video output from the Amiga by tying into the video signals by a small pin header. It would definately enhance for example the HXC floppy emulator.

This is already a reality on Atari ST and Amstrad CPC (without the need to hack the keyboard/video output).
Amiga version is on the way.

is it just a firmware upgrade for the existing boards that would be required ?, or just software controlling boot ?

The firmware was updated some time ago to support a direct access to the sdcard through the floppy disk drive interface. The feature allows the host computer to browse the SDCard, read/write file on the FAT32 partition like on an hard disk. (i have some others project/experiments with this feature)

The other part is a program on the host computer able to access to the SDcard FAT32 partition, brownsing it, and reading/writing setting file of the emulator.
Please note that in this mode the host computer can access up to 32GB (max size of the SDCard )

You can download the Atari ST and CPC version here :

Is there going to be a cost-down version with no LCD, buttons & connectors etc?

Far better idea, and far simpler. I like it.

Zetr0: Surely AVR is powerful enough to do job of the FDD PIC as well. Or is there a specific reason why using a PIC would be better for the task?

I dont like the system disk approach, it means you would have to quit whatever you were doing to put the next disk in if you ever got the queue system wrong. Also it would be slow to load the "system disk". The OSD approach is a much nicer solution imo. It does look like a more complicated way to go though.
