Amstrad PC4386SX

The Amstrad PC4386SX placed a 20 MHz Intel 80386SX computer into an unusually small desktop case. Nicknamed the Baby PC or Shoehorn, it was promoted as one of the world’s smallest full IBM-compatible computers and could be paired with a specially commissioned compact monitor.

Despite its size, the PC4386SX supplied 4MB of RAM, an 80MB hard disk and VGA graphics, giving it the resources needed for DOS applications and early Windows software.

Notable Features

• Exceptionally compact system unit, widely nicknamed the Baby PC or Shoehorn.
• Supplied with 4MB RAM and an 80MB hard disk.
• A specially commissioned 8-inch monitor was offered to complement the miniature case.

Historical Significance

• Showed Amstrad experimenting with physical design rather than simply increasing processor speed.
• Its small enclosure was reused for the PC5000 family.

Collectors Notes

• The compact matching monitor is particularly difficult to find.
• Limited internal space and ageing storage make careful inspection important.
