Volt/Ammeter Conversion

Floppy IMG derived from archived files. Mount as FLP1 and boot using Minerva 1.98a1 ROM, 640 KiB and Toolkit II 2.32. Both voltage and current branches checked: 100 ohms and 0.001 A give a 9900-ohm multiplier for 10 V and approximately 0.1001001 ohms for a 1 A shunt. No physical circuit test. Basic functional check in sQLux, not a complete test or a test on physical QL hardware. Audio not tested. ROMs are not included.
