1. Vol 1 Vogel homebrew analog computer — Volume 1 — Overview & the documentary record What the machine is, who designed it, the three separate machines that carry the name, and exactly which documents this series stands on
2. Vol 2 Vogel homebrew analog computer — Volume 2 — The console and the programming field The enclosure, the designer's own panel key, the patch field read terminal by terminal against the schematic, the cable set, and the two facilities the machine deliberately does without
3. Vol 3 Vogel homebrew analog computer — Volume 3 — The linear computing elements Summers, integrators, the open amplifier and the coefficient potentiometers, walked with the schematic open — and the integrator input networks that do not come to the round numbers the panel implies
4. Vol 4 Vogel homebrew analog computer — Volume 4 — The non-linear elements The AD534K multiplier unit and the four functions patched out of it, and the eleven-segment sine generator built from selected zener diodes — counted breakpoint by breakpoint
5. Vol 5 Vogel homebrew analog computer — Volume 5 — Reference, supply, metering and monitoring The half of the board that computes nothing: the REF01 reference every coefficient is a fraction of, the converter that runs the machine off a wall adaptor, the precision rectifier feeding a deliberately coarse meter, and the lamp that catches what a voltmeter cannot
6. Vol 6 Vogel homebrew analog computer — Volume 6 — Programming the machine Machine units and scaling, and the twenty published worked examples re-derived and checked — including the one that returns a confidently wrong answer with every element apparently within range
7. Vol 7 Vogel homebrew analog computer — Volume 7 — The valve sibling, the replications, and a bench reference The 2010 vacuum-tube demonstrator and its Heathkit-derived amplifier, the two documented rebuilds and every part they had to substitute, and a consolidated reference drawn from all six preceding volumes
