Anyhow, I have put back the original rtl8102 and will make a trip to my friend tomorrow or on Thursday and try the mainboard in the machine again.

Ok, I will look for equivalent then.
Do you know if the new rtl8102 chip is "blank" without firmware?
It sure looks like it.
The RTL 8102 is physical network chip. The mac and firmware is in another chip. You can change it smoothly.

Ok so maybe I have killed the oscilator when I replaced the rtl chip.
I will know when I try the board in the machine again

Well, thank you for your help.
I will try the board as planned and try to source an equivalent oscilator.

Which equivalent did you use?
The ones I have found so far is obsolete.

Update!
Network connection is now working again with original RTL8102 chip!
But, in my search for errors I tested every possible thing I could think of and sadly did a factory reset on the machine.
Now we get error code 0101, Limit Position Initialize in the Service Mode has not been done.
I have follwed the steps in the service manual several times but get an error message at step 4, Position invalid out of range.
I have checked the limit sensor with the "Sensor check" in the service menu and I can see that the star "*" is present under letter "O" when the head is near the limit sensor.
That is were we are right now.

Run the encoder setup and then encoder calibration in service mode. Both are automatic adjustments. Then try the limit position again.

Yes I have both

When I try to run encoder setup I also get error 0101.
I have now found out that the printer head does not lock in place in the parking place.
I need to look at the locking mechanism that does not work.
Thanx for the input, I will try it when I get the head to lock in place.

Do you got spare parts for Roland machines?
We also have a SP-300 that I think the long head cable is broken.
It stops in random places while printing and we get an error message about the head not finding the sensor.
