I copied the Z8038 part from the book "The Z8000 microprocessor, A design handbook" by Bradly, K. Fawcett. I remember that somebody on the list tried to make a collection of zilog chip documents. I'd like to mail the 20 pages to him. Please send me email if it is you. Thanks. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
