DDI-1 interface

[salvogendut]

I am looking to purchase a DDI-1 interface for a CPC464 (either original or clone) . Ideally I should be able to connect an external drive/gotek to it and use easily. I am located in Italy

Slightly related: He also announced that he will close down his company end of the year.

Be aware that you need the original floppy drive to power the controller module. The controller gets its 5V from the floppy. Modification is possible but not too simple.

If you want a GOTEK anyway you should consider the DDI5 or DDI6 also made by Piotr. They combine the DDI with GOTEK and 512K RAM (DDI 6 also ROM board) in a single device. The price is a bit high but still cheaper than getting the individual parts and a lot less hassle as you don't have to deal with any modifications. 

There are also other expansions that might make sense. The ULIFAC and the upcoming PicoROM also provide DSK access, ram and rom and are much cheaper - but don't contain a real disk controller.

Ideally I'd want something simple with just an external connector for the gotek/disk (and the gotek/disk will be powered by an external power supply). Even though I like the idea of DDI5 and 6 they are expensive and I don't like that they are trying to be everything (ram expansion, FDC emulator and external connector). I'd be happy with something like a DDI with just the external connector. I have a ULIfAC already and I like it the way it is but would love to be able to connect a real disk to a 464

It's not that difficult, it just involves adding a wire to the DDI-1 PCB:

Thanks @Bryce !!! I wonder if there are DDI clones out there that can be easily built as DIY projects
