Plan C | Sinclair QL Fixes, White Screen, Easy Composite PAL, ATX Power Mod, MicroDrive Tests @Plan-C | Uploaded February 2019 | Updated October 2024, 3 hours ago.
Had these sitting around for a while with no power supply. Fix of one QL with a white screen (upper ram fault), replacement of keyboard membrane, composite PAL video without mods and how to power the unit inc microdrives from an ATX in a way that can be easily reversed later.
Later part shows my ham-fisted testing of the microdrives on two QLs with some cartridges from ebay and some attempts at fixing one microdrive which refused to read. 3/4 worked in the end.
Good Luck All.
