Enterprise PW360 Prototype

The Enterprise PW360 was a prototype office computer developed as the company sought a competitor to Amstrad's successful PCW range. It placed a faster Z80B processor, 360KB of RAM and an internal floppy drive in a sober grey system intended for word processing and business use.

The machine did not progress beyond the prototype stage before Enterprise Computers failed. Its change of styling and market direction illustrates the company's late attempt to move away from the crowded home-computer sector.

Notable Features

• 6MHz Z80B was faster than the processor used in the Enterprise 64 and 128.
• 360KB RAM and an internal disk drive targeted office applications.
• Grey business styling departed from the colourful home-computer design.

Historical Significance

• A rare surviving example of Enterprise's plan to enter the dedicated word-processing market.
• The project ended before production when the company collapsed.

Collector’s Notes

• The PW360 is a prototype, and surviving technical details are incomplete.
• It should not be confused with a normal Enterprise 128 fitted with an external EXDOS drive.
