Support Noel's Retro Lab on Patreon: / 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 • More QL videos from #QLvember: • #QLvember - Sinclair QL in November 2020 • More awesome music by McKlain: https://www.mcklain.com • You can also support Noel's Retro Lab on YouTube by joining this channel: • / @noelsretrolab • Connect with Noel's Retro Lab: • Discord ➤ / discord • Facebook ➤ / noelsretrolab • Twitter ➤ / noelsretrolab • Instagram ➤ / noelsretrolab • #SinclairQL #RetroComputer #QLvember
