PLUS 2A FDD Interface

Plus2AFDD - floppy disk drive interface for ZX Spectrum + 2A (black)

Light version of this interface is here https://github.com/konkotgit/PLUS-2A-FDC-LIGHT

• Built-in floppy drive emulator with FlashFloppy software
• Possibility of connecting a classic 3.5" drive simultaneously
• Floppy disk side switch.
• Standard capacity is 173K per diskette side.
• The ability to format a floppy disk to 720KB using the appropriate tools.
• Drive configuration A: emulator, B: 3.5 "drive or vice versa.
• READY signal enforcement for drives that do not have it.

Connecting the interface turns ZX Spectrum + 2A into ZX Spectrum +3

PCB board

Dear Konkogit

Do you have any version of the PCB with "normal components" instead of smd ones? For a person who has difficulty soldering these components it is a huge nightmare.

Thanks for your undestanding

Connect physical 3" drive?

Firstly, this is a really cool project, and thank you so much for sharing it! I am really looking forward to building it.

I have one question though - would it be possible to connect a real 3" external drive to the interface with the correct cable?
