Compaq Computer UK is now offering the new 80387 mathematics co-processor for its Deskpro 386 machine, and is making the machine faster by adding a disk cacheing program as standard: all new Deskpro 386s will come with sockets for both the 80387 and 80287, and existing users who want to add the new chip can swap their system board for one with the 80387 already installed for UKP750 – the price of the chip on its own – until August 31; in the US, the firm, which already had cacheing on the 386, added it on all hard disk machines; the Portable II is also off 10% at $2,700 for the Model 2, 11% to $4,000.
