## NC-Super89 Board and W5500 Application Overview

A recent project with the **NC-Super89 Wiznet/SD** board has demonstrated an interesting use of the **W5500 Ethernet Controller**, so I’d like to share a brief introduction.

### Heathkit H89 and the Role of NC-Super89

The **Heathkit H89**, released in 1979, was an **all-in-one Z80-based retro computer**.

It combined a keyboard, CRT monitor, and floppy drive into a single enclosure.

It typically ran CP/M and became a popular personal computer of its era.

Original hardware is now rare and difficult to maintain.

The **NC-Super89** board was developed to **recreate the H89 architecture** with modern FPGA/MCU hardware, enabling classic software to run again.

In short, it preserves the retro computing experience while adding modern expansion options such as Wi-Fi, Ethernet, and SD card storage.

### W5500 on the NC-Super89

The **NC-Super89 Wiznet/SD board integrates the W5500 Ethernet controller**, making it possible to enable Ethernet communication in the H89 environment.
