Socket 7 ATX motherboard for legacy builds

The Intel TC430HX is a Socket 7 ATX motherboard built around the Intel 430HX chipset. It targets enthusiasts assembling or repairing vintage systems that require a classic 66 MHz front-side bus and 512 KB of L2 cache. The board delivers a period-correct foundation for Pentium-class processors and supports up to 128 MB of system memory.

Verify SIMM memory and ISA card clearance

Before ordering, confirm you have 72-pin SIMM modules available because the board provides four SIMM slots and no DIMM sockets. Check that your chassis can accommodate three full-length PCI slots and two full-length ISA slots, as both run the full depth of the ATX form factor. Ensure your power supply includes the ATX connector style used by this generation of board.

DB-15 video header and dual IDE connectors

A 15-pin D-Sub header and two 40-pin IDC connectors handle video output and dual EIDE storage channels respectively. PS/2 keyboard and mouse ports are mounted on the rear I/O for direct peripheral attachment. The full-length expansion layout means long PCI or ISA cards will sit close to drive cages, so plan cable routing accordingly.

Questions about this item

Does the Intel TC430HX come with any cables or accessories, or do I need to buy IDE cables and PS/2 peripherals separately?

The board ships without accessories, so you will need to supply your own EIDE cables for the two 40 pin IDC storage connectors and PS/2 keyboard and mouse.

Should I choose 72-pin SIMMs or a different memory type to reach the 128 MB maximum on this board?

The board only accepts 72-pin SIMMs across its four memory slots, so matching SIMM modules are required to reach the 128 MB limit.

What does the 66 MHz bus speed mean for actual processor performance on the Intel 430HX chipset?

The 66 MHz front-side bus sets the data rate between the Socket 7 processor and the 430HX chipset, defining the baseline throughput for CPU, cache and memory transactions.
