- PPC G3 600MHz (We've left ColdFire atm)
- AGP slot
- PCI slots
- 2x SD-RAM slots
If you upgrade SDRAM slots to DDR you could use Marvell's Discovery II chips...
Plus you get an integrated gigabit ethernet ports. It is not custom design chip
but letting a standard chip to handle standard slots is not that bad.
I recall there was a computer using Discovery II chip, but can't remember its name right now 8-)
Marvell:-D
