Two topics. First: a systematic chip-swap procedure for diagnosing failed memory chips in a Sinclair QL Trump Card expansion board — removing the board cover, identifying the three memory chip banks, swapping chips one at a time into the critical first-position slot of the right bank (the only position that allows partial initialization), marking tested chips, observing whether the QL initializes fully or partially, and handling multi-chip failures. Power-off precautions are strongly emphasized. Second: a critical review of the PC-Conqueror MS-DOS emulator for the QL — benchmark test took 45 minutes vs. 59 seconds on a native 8MHz IBM clone, making it useful only for file transfer between QL and IBM-compatible systems.
