The Tandy Corporation holds a press conference to announce plans to build clones of IBM’s PS/2 system computers. The conference comes soon after IBM’s announcement that it would license patents on key PC technologies. IBM made this decision as they realized they were losing control of the “IBM-compatible” PC market and could make more money licensing the technologies. Within five years, IBM clones will become more popular than the original IBM machines themselves. Eventually IBM would leave the PC manufacturing business altogether, selling their PC division to Lenovo in 2005.

Electronics magazine publishes an article by Gordon Moore, head of research and development for Fairchild Semiconductor and future co-founder of Intel, on the future of semiconductor components. In the article, Moore predicts that transistor density on integrated circuits will double every eighteen months for “at least” the next ten years. This theory will eventually come to be known as Moore’s Law and has largely held true to this day. Controversy exists over whether Moore’s Law remains applicable, however time will tell just how long Moore’s Law will continue to remain true.

Newspapers report that IBM’s Model 3090 mainframe has become the first commercial computer to use a megabit memory chip, 4 times the storage capacity of the then current generation of 256 kilobit chips. To give context to that amount of storage, it was reported that a megabit chip could store over 1 million bits of data, which translated to about about 100 double-spaced typewritten pages. At the time most personal computers were still using 64 kilobit memory chips.

IBM wanted to make the announcement for two big reasons. First, the use of higher density memory could allow them to make their mainframe computers smaller, which would save their customers cost in floor space. But perhaps more importantly, they wanted to show that American technology companies in general and IBM in specific could keep up with Japanese companies in the highly competitive semiconductor market of the time. Lower-cost Japanese firms had captured 85% of the DRAM market and Fujitsu, Hitachi, Mitsubishi, NEC, and Toshiba were set to begin shipping megabit memory of their own. IBM was attempting to shed their reputation as being slow and stodgy as compared to the upstart Japanese. They even made promotional buttons with actual 1 megabit chips!

The Osborne Computer Corporation officially announced the Osborne Executive portable computer, the follow-up to its extremely successful Osborne 1. This is the computer that according to lore, took down the company. Known as the Osborne Effect, the legend is that by leaking the announcement of  this computer earlier in the year, dealers cancelled all orders for the Osborne 1, effectively destroying the company’s cashflow and hindering operations going forward. This resulted in the cancellation of the company’s IPO and eventually to bankruptcy.

The reality may not be so simple, but my research shows that the Osborne Effect may have been a contributing cause to the company’s demise, along with the rise of competitors, the introduction of the IBM PC, and mismanagement by the company’s president, brought in by investors to provide “adult supervision”.
