Sinclair QL Microdrives and Microdrive Repair (Part 3)
Support Noel's Retro Lab on Patreon: https://www.patreon.com/NoelsRetroLab
Let's have an in-depth look at microdrives, the storage technology of the Sinclair QL (and to a lesser extend the ZX Spectrum as well). It turns out one of the microdrives wasn't working, so I did some fault-finding and ended up replacing the microdrive ULA itself (which apparently it's not an uncommon problem) to repair the microdrive. Later I looked into re-felting a cartridge to make it functional again, and finally, I ran some speed tests vs floppy disks and even traditional audio tapes.
Chapters:
00:00 Intro
00:32 What is a microdrive?
04:07 Testing the microdrives
04:55 Microdrive fault finding
07:01 ULA diagnostics
16:43 ULA replacement
20:19 Re-felting cartridges
23:25 Microdrive performance
28:45 Conclusion
