Collection
Slide Rules
My most expansive collection. Slide rules are easy to store, repair, and use regularly.
Slide Rule Formatting
When describing layouts of slide rules, the following standard is used:
- scales are ordered from the top to bottom of the rule, separated by spaces
- parentheses "()" denote scales on the slide.
- scales placed back-to-back or on the same line are separated by a forward slash "/."
- scales are named as written on the rule, subscripts may be used to differentiate scales for clarity.
- ascending scales are written in black, descending scales are written in red (with the exception of Versalog cosine scales, to match the form on the rules).
| Model | Manufacturer | Layout | Size | Scales | Case | Acquisition Date | Notes |
|---|---|---|---|---|---|---|---|
| 67/87 Rb Rietz | A.W. Faber-Castell | Rietz | Pocket (5") | L K A (B CI C) D S ST T | Green zippered leather, includes stylus. | Feb. 5, 2023 | Includes addiator on the back of the rule. One of a few slide rules capable of all four elementary functions. |
| V.I. 70-80 | A.W. Faber-Castell | Simplex (specialized) | Pocket+ (7") | cm SRU SSU (°C °F C) D Centistokes Engler in. [front]

| № 601-1 | Diwa | Rietz | Pocket (5") | K A (B CI C) D L [front]
(S ST T) [back] |
dark brown leather case, stamped Cooper-Bessemer | Jul. 7, 2022 | Ordered by Cooper-Bessemer. Has extra marks for calculating circles on the cursor. |

dark brown faux leather, lined with felt. Broken top flap. | May 7, 2022 | My first straight engineering rule. Identical scales to the original Versalog, with the addition of an A scale, but no associated B scale. Has HV red hairline. |
| Versalog 1461 | Frederick Post Co. (Hemmi) | Duplex | Pocket (5") | LL0 LL/0 K DF (CF CIF CI C) D R1 R2 L [front]

LL0± LL1± DF (CF CIF Ln/L CI C) D LL2± LL3± [back] |
Tan leather, plastic hard liner glued in. | Ca. Dec. 1, 2022 | Came with unique gaskets between cursor and body (removed). |
| C10 KL1 | Unknown | Unique | Circular | A C [front]
Ci S T [back] |
None. | Apr. 28, 2022 | A Ukranian circular rule, the front and back scales process in opposite directions, acting as inverted scales of each other. The face of the front moves along with a needle, while the back only has the associated needle, the face being static. |
Mechanical Calculators
My original obsession. Mechanical calculators take more space and effort, so I have comparatively few.
| Model | Manufacturer | Style | Acquisition Date | Notes |
|---|---|---|---|---|
| C-113 | Facit | Pinwheel (ten-key entry) | Jan. 19, 2023 | The latest style of the Facit TK. Missing pointers for decimal places. |
| Abacus | Unknown | Soroban (Japanese) | Dec. 25, 2018 | Has a mechanical clearing mechanism, using a scissor arm to push beads back into place. |
Electronic Calculators
Newer collection, I am much less comfortable repairing and interacting with them.
| Model | Manufacturer | Style | Acquisition Date | Notes |
|---|---|---|---|---|
| Model 9104 | Kingspoint | ten-key Four Function (early) | Ca. May 14, 2023 | Early four function calculator, Uses a running tally input with two result keys. |
| TI-30X IIS | Texas Instruments | Scientific | Unknown | In use since High School. Not currently used in favor of other devices |
| TI-Nspire CAS Touchpad | Texas Instruments | Graphing | Jul. 12, 2023 | Battery contacts corroded, currently without OS or rechargeable battery pack. |
