The cards
Meyer designated the parts of the VIC by figure and by card — 8XA, 9XA, 9XB and the rest — and the replication community builds to the same names.
Part of the whole device list.
-
8XA Amp Inhibiting Circuit 53 records
Two copper wires bifilar wound about a magnetic induction core, to allow amp restriction. Assembled into the coil array it forms what Meyer calls the VIC Multi-Coil Spool Assembly.
-
9XA Voltage Intensifier Circuit 12 records
The circuit the whole subsystem is named for. Its component arrangement retards or prevents amp flow, and resonant action occurs when its inductive and capacitive reactance set up the condition.
-
9XB Variable Pulse-Width Triggering Circuit 15 records
The triggering card. Replicators build it as a variable pulse frequency generator, and gerbers for the board are in the archive.
Meyer also uses 9XB as a figure number in the Magnetic Spin Generator material, where it shows a variable gate circuit rather than the triggering card. Same designation, two drawings.
-
9XC Variable Gate Circuit 1 record
The gating card. The archive holds gerbers for the replication board.
-
9XD Gated waveform card 5 records
A card carrying gated waveform of variable amplitude, fed from the voltage regulator.
The sources disagree. Meyer's schematic calls PC9XD the gated variable-amplitude waveform card; the replication notes in this archive title 9XD "The 7805/7812 Voltage Regulator Supply", which is the supply feeding it rather than the card itself. Recorded rather than resolved.
-
9XE Sequential Gate Circuit 1 record
The sequencing card. The archive holds gerbers for the replication board.
-
The toroidal form of the VIC. In some cases it replaces the rotary circuit 9XG and the 9XA together, restricting amps while attenuating voltage.
-
The rotary form of the VIC. Used with resistive wire for the pickup winding to restrict amps further.
-
The rotary generator. The archive holds an analysis of it, notes on making the alternator, and its variable speed drive.
Descriptions here are quoted from a holding in this archive rather than written from general knowledge, and each page says which one. A device added while tagging photographs carries no description until somebody writes one from a source.
