HP-16C Collector's Edition Re-release

HP Re-releases the HP-16C Computer Science Calculator

An HP licensee has launched a Collector's Edition of the HP-16C, a classic computer science calculator originally released in the 1980s. The device is targeted at enthusiasts and collectors who value the specific functionality of the original hardware, particularly its capabilities for low-level programming and integer arithmetic.

Technical Capabilities of the HP-16C

The HP-16C is specialized for computer science tasks, distinguishing it from the general scientific calculators in the HP-15C or financial models like the HP-12C.

Low-Level Programming Support

  • Bitwise Operations: The calculator is highly effective for tasks involving "bit-twiddling" and low-level programming.
  • Integer Arithmetic: It is designed to simulate different types of integer arithmetic, making it a specialized tool for developers working with hardware-level logic.
  • Display Limitations: The original hardware features an 8-digit screen. In binary mode, this can be cumbersome when working with variables exceeding 8 bits, requiring users to scroll through the displayed number.

RPN Architecture

Like most classic HP calculators, the HP-16C utilizes Reverse Polish Notation (RPN). Users favor RPN for its efficiency in expression scaling and its ability to eliminate the need for parentheses in complex calculations.

Community Reception and Build Quality Concerns

While the re-release has generated nostalgia, experienced HP users have raised significant concerns regarding the build quality of modern "Collector's Edition" (CE) releases.

Comparison to Original Hardware

Users report that original HP calculators from the 1980s are exceptionally durable, with some reporting that silver oxide batteries have lasted over two decades. However, critics of the newer CE models, specifically citing the HP-15C CE, note several regressions:

  • Key Feel and Labeling: Reports suggest the newer versions do not match the original's tactile feedback or color labeling.
  • Display Quality: The display on the CE models is noted as being inferior to the original hardware.
  • Aesthetics: Some users find the back casing of the CE models to be visually unappealing compared to the original designs.

Market Alternatives

Several enthusiasts recommend third-party alternatives from SwissMicros, such as the DM16C, DM16L, and DM41X. These devices are described as being "built like absolute tanks" with anodized metal back plates and high-quality construction that often exceeds the quality of official re-releases.

User Insights on HP Calculators

Technical users continue to value these devices for their specific ergonomic and functional advantages:

"The main thing is that the keys still work like on day 1. And I've never seen a calculator with keys like this, with such feedback that you never need to worry about double-presses or missed-presses."

"The beauty of an RPN calculator was that nobody asked to borrow it."

For those seeking an original experience, some suggest that sourcing a working original HP-16C via eBay may be more cost-effective than purchasing the new Collector's Edition.
