+D IDE Disk Drive Controll Clone for ZX Spectrum Computer Systems

This was a project i downloaded from the web after needing to access floppy drives on the ZX Spectrum. There is also the ability to access Hard Disk Drive systems, as well as provide a Kempston Joystick Interface. Quality of the PCB is amazing, and was produced on what feels like a very capable PCB Board, ready for some wear and tear. I must disclaim I am not the PCB designer but the project is available until Open Source Hardware scope. You will need to source some hard to obtain IC's, like the WD1772 which controls the Floppy Disk Drives, however some alternatives are available. Otherwise the project makes use of the commonly available 28C256 EPROM IC, logic chips, diodes, pin headers and so on, so can be easily maintained. IC'S 4 & 11 will require use of GAL programmable ICs, the JED code files are out there on the net.
