🌟 Ultimate Retro Gaming Machine: AST Advantage! 9413 (P200 MMX, Dual HDDs, Win 98 SE) 🌟


Ready to Power On! This exceptional AST Advantage! 9413 desktop is a collector's dream, perfectly configured for classic DOS and Windows 98 SE gaming. Featuring the highly flexible Pentium 200MHz MMX platform, this machine is a functional piece of computing history, validated by the retro community as an ideal system for the late 90s era.


🏆 VOGONS Community Vetted Components for Retro Excellence


The configuration of this AST Advantage! 9413 aligns perfectly with the "sweet spot" components often discussed and recommended by the retro gaming experts at VOGONS.org:


* Pentium MMX 200MHz: "The Pentium MMX gets a huge thumbs up—this is one of the best retro PCs that you can have," and is "powerful enough for the early 3D games like Doom and Duke Nukem 3D."


* P200 MMX Versatility: This CPU is considered the "sweet spot" because it can be sufficiently slowed down for speed-sensitive older DOS titles while still handling later Windows 98 games.


* Sound Blaster Compatibility (CRITICAL!): The integrated ESS AudioDrive chipset is lauded for providing "very good Sound Blaster Pro compatible sound" in DOS, making it an affordable and highly functional replacement for classic Creative cards.


* Integrated OPL3 Sound: The ESS chip features a high-quality, integrated OPL3-compatible FM synthesizer (ESFM), offering an authentic soundtrack experience for thousands of classic DOS titles. Plus the essential Sound Blaster compatibility!


* S3 ViRGE (325) Graphics: The integrated ViRGE chip is "a very good choice" for a Pentium/MMX system and is known for its "very good 2D performance" in both Windows and DOS, which is paramount for the majority of late 90s titles.


* Dual Hard Drives: A setup like this is highly practical, providing "ample space" for both Windows 98 and DOS partitions, a "quality of life improvement" often pursued by retro builders.


* ISA Slots: The availability of ISA slots is key for enthusiasts who wish to upgrade with specialized audio cards (like a high-end Sound Blaster or Gravis Ultrasound) for ultimate compatibility.


Cosmetic could use either two more drives to fill the space or a plastic panel (I put the one that’s on there for now) and the power button works fine and you can press it fine with your finger but it could use the plastic piece for cosmetics. Everything works great though.

The onboard sound chip in the AST Advantage! 9413 is part of the excellent ESS AudioDrive family (the ESS ES1869F) which is a feature-rich integrated solution that was a very popular and versatile sound solution used by many OEMs in 1996-1997.


Here are the full granular details of the onboard sound:


AST Advantage! 9413 Onboard Audio Granular Specifications

| Feature | Granular Detail | Significance for Retro Gaming (DOS/Windows) |

|---|---|---|

| Chipset | ESS AudioDrive (Likely ES1869F) | A highly regarded sound chip manufacturer, known for reliability and superior compatibility over many Creative Labs clones. |

| Interface | ISA Bus (Logic on the motherboard) | Although physically on the motherboard, the chip uses the ISA bus for DOS communication, which is the native interface required by almost all classic DOS games. |

| Digital Audio (PCM) | 16-bit Stereo | Supports stereo digital sound at a high sample rate (up to 48 kHz in Windows, 22 kHz max in DOS SB Pro mode). |

| Compatibility (Digital) | Sound Blaster Pro 2.0 | Crucial compatibility for DOS. Supports 8-bit stereo digital sound (22 kHz max), which is required by many titles for stereo sound effects. Also fully compatible with the older Sound Blaster 1.x/2.0 (8-bit mono). |

| Music Synthesis | ESFM™ Synthesizer | This is ESS's in-house OPL3 superset FM synthesizer. It is fully Yamaha OPL3 compatible (the standard for FM music in DOS games) but also supports an enhanced Native mode with more complex voicing (which a few later DOS games can use). |

| Wavetable Music | Wavetable Synthesis Support | While not a dedicated hardware wavetable, the ES1869 is often paired with an internal software wavetable driver (like the AudioRack) in Windows 95/98 to provide General MIDI playback, often utilizing the system RAM for the soundfont. |

| MIDI Interface | MPU-401 UART Mode | Provides a standard MIDI interface via the integrated Game Port. Essential for connecting an external MIDI module (like a Roland Sound Canvas) for high-quality General MIDI music in games. |

| I/O Ports | Line-In, Line-Out, Microphone (3.5mm) | Standard ports integrated on the motherboard's rear I/O panel. |

| Game Port | Integrated Dual Game Port (DB15) | Supports two standard analog joysticks or one MIDI interface connection. |

| Duplex | Full-Duplex Operation | Supports simultaneous recording and playback, a key feature for early Internet telephony and modern conferencing applications in Windows 98. |

| CD-ROM Interface | IDE CD-ROM Interface | Includes a dedicated IDE connector header on the motherboard for the CD-ROM drive audio signal. |

In short: The onboard sound is one of the best "Sound Blaster Pro clones" for a late-90s OEM machine, providing high-quality digital audio, faithful OPL3 music, and excellent DOS compatibility without needing to sacrifice an expansion slot.
