Newer Technology’s iMAXpowr G3 466 processor upgrade for iMacs becomes available in the UK from this month, Steve Hawkins of Newer’s UK distributor, AM Micro told Macworld today.

The iMAXpowr G3 466 replaces the stock iMac processor card, giving older Macs a 466Mhz G3 processor, 1MB backside cache and a 155Mhz cache bus. The upgrade is compatible with current Mac operating systems. In the UK, the retailer, rather than the iMac’s owner, performs the installation.

AM Micro said that the product will cost £389, and will be available in limited quantities through selected dealers. Call AM Micro, 01392 426473 for further details.
