Front view of the NetBlazer PN2. It is a relatively small device, about the size of a phone book or dictionary. It has a floppy drive and some status lights on the front.

1. Introduction

The Telebit NetBlazer PN2 (circa 1993) is a router/RAS device designed to connect remote sites by dialing them up with an attached modem. It comes with a rudementary OS that acts a little like UNIX and has limited support for loadable modules.

Two striking features of the NetBlazer PN2 are its ability to boot from a built-in floppy drive, and its 386 CPU. While the CPU is a 386, the architecture is apparently incompatible with that of the IBM PC.

Inside view of the NetBlazer PN2. The commodity floppy drive is mounted to the motherboard from the bottom. The Intel i386 CPU is a relatively tiny surface-mount package located closest to the viewer, next to the VLSI chipset.

It also includes a built-in Ethernet RJ-45/BNC/AUI port and two serial ports for connecting modems or direct RS-232 serial connections.

2. Boot Disk

Fortunately, our NetBlazer PN2 came with a working boot diskette. We have made it available at The Internet Archive. It has a configuration on it which is invalid by now, but provides a starting point to get to a working configuration.
