[Coco] Cheap generic gotek drives

[Deny Wilson]

Anyone that's more a fan of open hardware, there is an open implementation
of a Gotek drive called OpenFlops. It has some interesting features, like
the ability to emulate 2 drives at once, It runs FlashFloppy by default. It
can support the OLED screens, the speaker and rotary encoders just like a
Gotek. It has the programming headers already soldered in, for those who
don't like soldering. It will fit in a standard Gotek case, as well. I
don't think it's any cheaper than a Gotek. In fact, depending on your
currency's exchange rate with GBP, it may end up being more expensive. But
it is open hardware, so you could buy the PCBs and the other components and
build one yourself.

I do not own one, but I plan on purchasing one at some point for my Amiga.
