Plus/4 Programmer's Reference Guide
I read with interest your reply to Sean Donovan in the May 1986 installment of "Readers' Feedback," regarding custom character sets on the Commodore Plus/4. The Plus/4 Programmer's Reference Guide is now available from Scott, Foresman, 1900 East Lake Ave., Glenview, Illinois 60025. This book, which I coauthored with Sarah Meyer, contains material on all the graphics modes of the Plus/4, as well as a complete description of BASIC 3.5, the built-in software, and the use of machine language and peripherals. I hope you will make this information available to your readers.
Thank you for the information.
