AMD Geode/Video 1/Script

This is a textual script of the video.

Introduction

My DOS Programming playlist on YouTube scrolls down the screen.

Voice: "I've been writing a DOS program for a while now"

The DOSBox-X home page scrolls down the screen.

Voice: "I've been using DOSBox but it would be nice to use real hardware"

A picture of an IBM PC XT taken by Ruben de Rijcke is shown on the screen with big green "IBM" text on it.

Voice: "Ideally I'd use an actual period accurate IBM PC"

A screenshot of expensive eBay listings scrolls past. One is shown to cost $500 AUD.

Voice: "But these are really expensive"

An eBay listing titled "Vintage Advantech PCM-9375 REV. A1 SBC Single Board Computer - AMD Geode LX800" is shown. Its status is marked as "For parts or not working, sold as-is with no guarantees." It's listed as $50 AUD.

Voice: "Checking eBay I found and industrial single-board computer for $50"

The listing description is shown. It clarifies: "For sale here is an Advantech PCM-9375 REV. A1 single board computer. Previously, I was able to boot Windows 98SE from a Compact Flash card and everything worked fine. It currently refuses to output a video signal that any of my monitors can recognise, so it's being sold as-is for parts with no guarantees. For a full spec sheet, see Advantech's site."

Voice: "The low price is just due to it's video output being broken. Most computers are designed to be useless without video output so naturally this is seen as garbage."

A receipt showing payment for the board is shown. It cost $50 AUD with free shipping. It was paid on 7 November 2021 and delivered on 12 November 21.

Voice: "I bought it anyway."

A hand is shown placing the board on a table. It is an unprotected circuit board with its chips, connectors and pin headers exposed. One large heatsink covers the CPU and another smaller heatsink covers the companion chip.

Voice: "So here it is: The PCM 9375. It stars a Geode LX800 CPU and CS5536 companion chip."

A small stick of RAM is shown.

Voice: "512 megabytes of DDR1 RAM."

An empty CompactFlash connector is shown.

Voice: "CompactFlash for storage."

The side of the board is shown with four ports: A DB9 serial port, an Ethernet port, a PS/2 keyboard port and a VGA port.

Voice: "A serial port, an Ethernet port, a PS/2 port, VGA port"

A daughterboard connected to the main board is shown, with an Ethernet port on it as well as a mini USB connector. The board is unplugged already, and pliers are used to remove it entirely.

Voice: "As well as a mini USB port and a second Ethernet port. We're just going to remove those for now while we troubleshoot."
