Super Voyager VLB-III © 199? AMI [American Megatrends, Inc.]
The Super Voyager VLB-III is a premium workstation-grade 80486 Baby AT motherboard engineered and manufactured directly by American Megatrends, Inc. (AMI) around 1993 to 1994. Built to exceptional industrial and enterprise standards, the board centers around a standard 168-pin Socket 2/3 layout driven by AMI's proprietary core logic chipset architecture (often referred to as the AMI Goliath or early high-integration series). It supports a full range of 486 processors, including Intel 486SX, DX, and clock-doubled DX2 microprocessors running at Front-Side Bus speeds of 25 MHz or 33 MHz. To ensure maximum data throughput for CAD workstations and early local network servers, its physical expansion design includes two high-performance 32-bit VESA Local Bus (VLB) slots lined up alongside seven rugged 16-bit ISA slots. Memory handling relies on a robust array of eight 30-pin SIMM sockets paired with an expandable high-speed L2 static cache (SRAM) matrix supporting configurations up to 256 KB.
The Hardware Manufacturer Identity: While 95% of PC retro-builders associate AMI strictly with the iconic flashing AMIBIOS startup screen found on third-party hardware, AMI was actually an elite tier-1 motherboard designer during the 286, 386, and 486 eras. Their in-house manufactured Voyager and Enterprise mainboards were highly expensive, renowned for their heavy multi-layer PCB shielding, and primarily deployed in mission-critical corporate computing environments rather than low-end home clones.
Perfect Chipset & Firmware Synergy: Because AMI designed both the physical system logic chips and the code structure of the BIOS ROM, the Super Voyager VLB-III boasted legendary stability. It bypassed the timing glitches and memory sub-bank compatibility problems common on generic boards that had to combine budget chipsets (like early OPTi or UMC) with licensed, non-optimized BIOS revisions.
