QL-SD

Background

Originally I only wanted to make my personal QL-SD work with my GoldCard. In the end that was quite a lot of work and as there are no new QL-SDs produced I created my own version of it. Then I put a lot more work into the software, too (based on Wolfgang Lenerz excellent work). Here are the supporting files and documentation.

For more information about the history check my blog.

Supporting files

QL-microSD

With the microSD board both MDV drives can stay in the QL. It is simply fastened using a powerstrip and there is a small activity LED that points towards the back. The slot (like the bigger boards) is push-to-eject.
