I think this must be quite old news. http://www.microcontroller.com/news/Zilog_Sells_Crimzon_Zatara.asp "However, with the exit of Dr. Norm Sheridan as head of Engineering, as well as the departure of almost all of Zilog's experienced design engineers, Zilog's present management does not intend to develop any new silicon because they no longer have a design engineering team. Only two or three semiconductor design engineers remain with the company." I was actually browsing the Maxim site since they visited me today (for DAC and ADCs). But then I notice that they have the IR MCU suddenly. Then I noticed that Zilog has sold of the IR MCU and ARM9 Secured MCU lines to Maxim. I learned about the Z80 along with Intel MCS51 for my university MCU course. Nobody was interested in the Z80 then since 8051 and 8098 was popular at that time in China. But the lab equipment was there and the teacher thought it was not too bad to teach Z80 before the next course (8088 assembly and PC interface). -- Xiaofan http://mcuee.blogspot.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
