Written by Mark Baxman in Retro PC gaming

Assembling a retro PC is a rewarding project for enthusiasts who want to relive the golden age of computing or explore the roots of modern technology. Whether you’re aiming to recreate the experience of using a DOS-based gaming rig or a vintage Windows workstation, building a retro PC involves selecting the right components, understanding compatibility, and setting up the software.

This guide will walk you through the process of assembling a retro computer step-by-step, from planning to booting up.

1. Planning Your Retro PC Build

Determine the Purpose of Your Retro PC

Understanding your goals will guide your choices:

  • Gaming: A DOS-based PC for classic games like DOOM, Wolfenstein 3D, or Monkey Island.
  • Productivity: A vintage system for running old software like Lotus 1-2-3, WordPerfect, or early versions of Microsoft Office.
  • Learning and Exploration: A general-purpose retro system to experiment with vintage operating systems and hardware.

Choose an Era to Recreate

Retro PCs span several generations, each with distinct hardware and software:

  • 1980s: Systems running MS-DOS or CP/M. Ideal for early gaming and BASIC programming.
  • 1990s: Windows 3.1, Windows 95/98, and advanced DOS games.
  • Early 2000s: Windows XP-era systems for late-90s gaming and software.

Set a Budget

Retro PC components can range from affordable to highly collectible (and expensive). Determine how much you’re willing to invest, especially for rare items like graphics cards or vintage CPUs.

2. Selecting Components

Essential Components for a Retro PC

Here’s what you’ll need to assemble your retro PC:

1. Motherboard

  • Choose a motherboard compatible with the era’s CPU and expansion cards.
  • Look for models with ISA or PCI slots for vintage peripherals.
  • Common brands: ASUS, Gigabyte, and Intel for the 1990s.

2. CPU

  • 1980s: Intel 8086, 286, or 386.
  • 1990s: Intel 486, Pentium, or AMD K6 processors.
  • Early 2000s: Pentium III/IV or AMD Athlon XP processors.

3. Memory (RAM)

  • Match the type and speed supported by your motherboard:
    • SIMM (30-pin or 72-pin) for 1980s and early 1990s systems.
    • DIMM (SDRAM) for later systems.
  • Typical capacities range from 1 MB to 128 MB, depending on the era.

4. Storage

  • Hard Drive:
    • IDE drives were common in the 1980s–2000s. Look for sizes between 40 MB and 10 GB.
  • Floppy Drives:
    • 3.5-inch and 5.25-inch drives for software installation.
  • Optical Drive:
    • CD-ROM drives became popular in the mid-1990s.

5. Graphics Card

  • 1980s–early 1990s: VGA cards like Trident or Cirrus Logic.
  • Mid-1990s: 3dfx Voodoo or NVIDIA RIVA cards for 3D acceleration.
  • 2000s: GeForce 4 or Radeon 9000 series.

6. Sound Card

  • A sound card significantly enhances the experience of gaming and multimedia:
    • AdLib and Sound Blaster 16: Popular for DOS games.
    • Gravis Ultrasound: For superior audio in games like Descent.

7. Power Supply Unit (PSU)

  • Use a PSU with appropriate connectors for older hardware (AT or ATX standard).
  • Ensure it provides sufficient wattage for your components.

8. Input Devices

  • Keyboard and Mouse: Look for PS/2 or DIN-style connectors, depending on your motherboard.

9. Monitor

  • CRT monitors are ideal for an authentic experience, though VGA-compatible LCDs are a modern alternative.

Where to Source Components

  1. Online Marketplaces: eBay, Craigslist, and Facebook Marketplace often have retro PC parts.
  2. Retro Computing Forums: Communities like Vogons or Reddit’s r/retrobattlestations.
  3. Local Thrift Stores or Electronics Recycling Centers: Great for discovering rare hardware at a low cost.

3. Assembling the Hardware

Step 1: Prepare Your Workspace

  • Use an anti-static mat or wrist strap to avoid damaging components.
  • Gather tools: Phillips-head screwdriver, tweezers, and cable ties.

Step 2: Install the CPU and Memory

  • Attach the CPU to the motherboard, ensuring proper orientation.
  • Secure the CPU cooler or heatsink.
  • Insert the RAM modules into their slots, pressing firmly until they click.

Step 3: Mount the Motherboard

  • Place the motherboard inside the case, aligning it with the standoffs.
  • Secure it with screws, taking care not to overtighten.

Step 4: Connect Storage Drives

  • Mount the hard drive, floppy drive, and CD-ROM drive in the case.
  • Connect the IDE or floppy cables and power connectors to each drive.

Step 5: Install Expansion Cards

  • Insert the graphics card, sound card, and any other peripherals into the appropriate slots (ISA, PCI, or AGP).
  • Ensure each card is seated firmly.

Step 6: Connect the PSU

  • Plug in the PSU connectors to the motherboard, storage drives, and expansion cards.
  • Organize cables to ensure proper airflow.

Step 7: Attach External Devices

  • Connect the keyboard, mouse, and monitor.
  • Double-check all connections before powering on the system.

4. Installing the Software

Step 1: Prepare Boot Media

  • Create bootable floppy disks or CDs for your operating system. Common choices include:
    • MS-DOS: Versions 5.0 or 6.22 for 1980s–early 1990s systems.
    • Windows 95/98: For late 1990s builds.
    • Windows XP: For early 2000s retro PCs.

Step 2: Boot the System

  • Power on the PC and enter the BIOS/CMOS setup (usually by pressing a key like DEL or F2).
  • Set the boot order to prioritize the floppy or CD-ROM drive.

Step 3: Install the Operating System

  1. Insert the boot media and restart the system.
  2. Follow the installation prompts to partition the hard drive, format it, and install the OS.
  3. Install any necessary drivers for the graphics card, sound card, and other peripherals.

Step 4: Add Software

  • Install essential programs like file managers, games, and productivity tools.
  • For gaming builds, configure the sound card and graphics settings for optimal performance.

5. Testing and Optimization

Run Diagnostic Tools

  • Use utilities like MemTest86 or DOS-based diagnostic software to check system stability.
