In This BYTE

On the cover, artist Robert Tinney has provided a scene depicting the combination of computers and golf handicapping described by Dr. George Haller in his article.

How would you like a PDP-ll/40 in your basement computer room? The price would probably be too high for the typical amateur. But Digital Equipment Corporation also makes the LSI-ll, a microcomputer which implements the PDP-ll/40 instruction set and inherits a wealth of existing PDP-ll software. Turn to Bob Baker's article on the LSI-ll for a summary.

How do you draw a picture on an oscilloscope display? Add a Light Pen as described by Sumner Loomis, and you will be able to add and delete points of light.

When the LIFE program can't figure out a key code, it calls DEFAULT, as described in LIFE Line 3. This issue's LIFE Line 4 specifies the DEFAULT routine used to enter cursor motion control data and numeric data for the KEYBOARD INTERPRETER. As a combined hardware and software system, the LIFE application enters the realm of hardware for the first time with a simple circuit to interface the cursor motion control keyboard and an ASCII keyboard via the same input port.

Wire wrapping is a technique often used to assemble circuits. Turn to Photographic Notes on Wire Wrapping for some pointers for your own custom computer interfaces .

According to tradition, no computer is ever complete without blinking lights. But There's More to Blinking Lights Than Meets the Eye, or the control panel designer's utilitarian motives. This issue provides a few ideas for using simple and inexpensive LED indicators in ways far removed from the traditional control panel application.

In the October BYTE, Richard Gardner commented on the application of personal computers in household situations. In this issue, Ted Lau continues on that theme with an article of "structured speculation" on the Total Kitchen Information System (TKIS).

Computers solve problems, right? One problem which golfers have is calculating handicaps so that duffers can play against pros in the same tournament. In Golf Handicapping (or: Buy a New Peripheral with Money Earned from Your Local Duffers), Dr. George Haller describes a program he concocted to serve as the bas is for a part time business calculating golf handicaps at his country club. For readers with teenage children, this might make a great opportunity for the kids to make some money to help pay for college expenses while learning how to run a business.

Computer systems have many resources which can be used by the person who assembles or modifies the design . One resource which is very important is the memory address space inherent in the design of the computer. Taking Advantage of Memory Address Spaces by James Luscher can provide important improvements in speed and function of your system.

What is style? In his article K or k?, Manfred Peshka describes some notational conventions which apply to BYTE's unique combination of hardware and software information. While the change of these standards is incomplete in this issue, future BYTEs will employ the standard abbreviations and units throughout.

What is one of the most useful peripherals? Why , the television set of course. To use the TV you need an interface. One such interface is the CT-l024 product by SWTPC reviewed by Jim Hogenson.
