Amstrad PC6486SX

The Amstrad PC6486SX was the sole model in Amstrad’s PC6000 desktop series. It brought Intel’s 32-bit 80486SX processor to the compact case style used by Amstrad’s earlier PC4386SX and PC5000 machines.

Typical systems used a 25 MHz processor, 4MB of expandable RAM and VGA graphics, offering a practical platform for DOS 5 and Microsoft Windows applications in the early 1990s.

Notable Features

• Only known model in Amstrad’s PC6000 desktop series.
• 25 MHz 80486SX processor and 4MB RAM, expandable to 32MB.
• Continued the compact desktop styling of the PC5000 family.

Historical Significance

• Marked Amstrad’s transition from 286 and 386 systems to the 486 generation.
• Used increasingly standard PC components rather than the more distinctive architecture of Amstrad’s earliest compatibles.

Collectors Notes

• Documentation and complete systems are comparatively scarce.
• Check the backup battery and storage devices before powering a long-stored example.
