Louis, there is a fellow in Germany that makes a Z280 computer called the 
CPU280. The November/December issue of The Computer Journal had an 
article by the designer describing it. Contact Tilmann Reh at In der 
Grossenback 64, W-5900 Siegen Germany for more information.

Sorry, I don't know of any plug-in boards to upgrade to the 280.
