No. Our engineering priorities and resources make it impossible for us to support these systems and also move the BeOS forward. It's a hard decision, but we're a very small company (fewer than 30 engineers), and we have to make hard choices about what we work on. Unfortunately, this means that 601-based Power Macs will not be able to run the BeOS.
Owners of the Power Mac 7500, however, are able to upgrade their processor card to a 604 card, and will have a faster Mac OS system, as well as a BeOS Ready System.
