April, 2005 Clive Maxfield -- Is publishing this year his latest book "How Computers Do Math" including in a CD with a virtual calculator program used as an example. The idea of the book is to provide a calculator interface "sitting" on top of a virtual 8-bit computer that runs on a PC. The readers are guided in creating a program in assembly language to make the calculator work. In its closing chapter entitled "Further Experiments", the author is encouraging the readers to write the assembly code to provide in the unassigned calculator buttons the X-Number functionality. A chapter has also been included in the book explaining the X-Number concept, and the CD will contain a folder with additional details of the X-Number methodology. More information on this book can be found at http://www.DIYCalculator.com. Other books published by this author are "Bebop to the Boolean Boogie (An Unconventional Guide to Electronics)" and "The Design Warrior's Guide to FPGAs" -- you can find them both on http://www.amazon.com. To know more details on the books published by Clive Maxfield and Alvin Montrose, visit http://www.maxmon.com/ Another interesting site is http://www.epemag.com home of the Everyday Practical Electronics (EPE) Online magazine. This is an electronics and computing hobbyist magazine – there’s a print issue in the UK. Mr. Maxfield is the editor/publisher of the online version. |
