If you have ever stared at an unidentified ISA card and wondered which two plastic jumpers will either fix it or ruin your afternoon, Total Hardware 99 is the kind of archive you want nearby.
Visit the surviving Total Hardware 99 archive
The site preserves a huge hardware-reference database from the era when configuring a PC often meant moving jumpers, flipping DIP switches and consulting photocopied diagrams whose originals had disappeared years earlier.
The surviving pages cover motherboards, modems, controllers, network hardware, video cards and other expansion devices. Entries are organized less like modern reviews and more like service notes: manufacturer, model, bus type, chipset, processor, memory limits, connectors, configurable settings and jumper positions.
A motherboard page is basically a wiring confession
One representative entry documents a JS-168A 80286 motherboard.
It lists a 12 MHz processor, up to 4 MB of onboard DRAM, several possible BIOS families and connector positions for the power LED, keylock, reset switch, speaker and turbo controls.
Then it gets to the reason archives like this survive: tables for wait states, turbo selection, monitor type, parity, DRAM bank population and jumper combinations.
That information is boring right up until you need it.
The modem section is even more sprawling. One page for 8-bit ISA modems runs through products from 3Com, US Robotics, Acer, Boca Research, Compaq, Hayes, Diamond Multimedia and dozens of companies that barely exist in current search results. Model names include everything from 1200-baud boards to 56K voice faxmodems.
For retrocomputing work, exact model strings matter. So do obscure revisions.
A card labeled M144IW is not interchangeable as research evidence with a generic statement that Boca once made modems. A jumper table for one motherboard revision can be useless—or dangerous—when applied to another.
Total Hardware 99 preserved that specificity.
The design reflects the task. There is little storytelling because the original user was probably holding a screwdriver and trying to make a machine boot.
That makes the archive a strong example of old technical Web publishing. It captures information that manufacturers often treated as disposable because each product generation made the previous one commercially irrelevant.
Decades later, the commercial value may be gone while the repair value has increased.
A modern support site usually begins with “select your current product.”
Total Hardware 99 begins from the more realistic retrocomputing question: “What on earth is this board?”
