In This Byte
In the Christmas BYTE you'll find the following morsels:
To quote an ancient philospher, "nature abhors a vacuum." Chris Ryland's Opinion: The Software Vacuum describes a void in the personal use computer marketplace. Will nature in the form of profit motive come in and fill the software vacuum? Only time will tell ...
Strange things sometimes occur in the electronic pathways of a computer. Putting on your detective hat may occasionally be required - in which case Alex. F. Burr's review Logic Probes - Hardware Bug Chasers will give you valuable information on several commercial products which can help debug your designs.
On the same theme but in the foreground this time, Robert Baker and John Errico have provided an article on a fairly sophisticated Powerless IC Test Clip which you can construct for $20 or so in parts. For the do-it-yourselfer, this design results in 16 little binary voltmeters which can be clamped onto an integrated circuit to examine the logic levels at each pin.
What is a Character? You can find out by reading Manfred Peshka's tutorial on some of the basic concepts of programming and information systems work. Old hands at the programming arts will find this to be an interesting review, and readers new to programming will find it necessary background material.
After an interruption, the LIFE Line series continues this month with the third installment. In LIFE Line 3 you'll find the beginning of information on the interactive commands which are decoded by the program.
The Flip Flop is an important element in designs used with computer chips and peripherals. William E. Browning has provided this article to introduce the less experienced readers to this fundamental building block.
Read Only Memory Technology can be used in situations ranging from clever logic and interface design to storage of systems programs in a computer. In his article on the subject in this issue, Don Lancaster gives some background information about ROM applications and several suggestions concerning their use as design elements.
What is The World's Smallest Computer System? Well, at this time it looks like the HP-65 pocket-size programmable calculator might qualify for the title. Find out why by turning to Richard Nelson's article on the subject.
The last BYTE featured a comparison of the Motorola 6800 CPU chip with a new contender from MOS Technology. In this issue, Gary Kay of Southwest Technical Products Corporation presents some information on the Motorola 6800 package his firm is supplying. What SWTPC has done is to take the standard parts, combine them with an attractive case, power supply and PC boards - and put the result into a package as a kit for readers to build.
What is it like to build an Altair computer kit? In his First Person Report: Assembling an Altair, John Zarrella describes his experience with the MITS product, from his decision to purchase, through assembly and hardware debugging.
Computers are fundamentally synchronous machines they beat to the tune of a periodic clock. With program timing loops, a computer can be made to count the beats of its clock. You can find out how to do this by reading Jim Hogenson's article Can Your Computer Tell Time?
When assembling complicated logic systems, one of the best methods for new and experimental work is use of solderless wire wrap interconnection. Some pointers on prototype assembly are found in Photographic Notes on Prototype Construction.
And on the cover, artist Robert Tinney illustrates the impact of these new toys upon traditional relationships.
