Picture of what ever it is that i have…. Just got from ebay today…

The CPU is a FULL 040 25mhz, its got ethernet chip… but the pads that need a 20mhz crystal are not populated.





The reason i am confused is after reading this---

So looks like i have to give the ethernet its own clock. so i can replace the 10mhz CPU Crystal with a 15mhz one
