I got my CoCo SDC from Zippster today and it works great. My first computer (COCO2) is going to get a lot more use now because of this thing. Just copy .DSK files to the sd card and you can mount them with out fuss. Even multi-disk OS9 SIERIA games work with out issue. The firmware lets you manipulate the images right from the CoCo so it doesn't need to be hooked to a PC or anything.
The coco's radioactive green looks glorious on a 55" LG 4K TV 😆
