SPARC Product Directory - since 1992
from the makers of
sparc product directory

the SBus Product Directory

by Zsolt Kerekes, editor and publisher
In 1992 I published an independently researched buyers guide called the SBus Product Directory which included details of every SPARC compatible card, notebook, workstation, server and blade (we called them SBCs in those days) from every company in the Sun compatible market.

To research the book I contacted hundreds of computer companies worldwide and asked them about their intentions in the Sun market.

I had previously worked for about 5 years in the Sun market and had already used, benchmarked, integrated or evaluated products from many companies as part of a high performance systems integration business.

In many of our systems - an embedded Sun workstation was the cheapest (and slowest) piece of hardware.

I didn't plan to be a publisher and I thought the first edition of the book would be it. But I realized that the SPARC market was growing and I might be able to make a living by continuing to research and sell new editions of the book - and the worldwide database of Sun resellers and integrators that I had researched along the way.

Customers of these information services included Sun themselves - who used it in every sales US sales office to support customer questions about 3rd party hardware. At the time I would have preferred it if all customers bought their own books. Some did. (The bigger ones.) But most alas didn't.

It was difficult making money from directly marketing a printed book worldwide. And I kept it up to date - producing new editions at every print run.

Selling SPARC mailing lists helped to cross subsidize my book - but it was the web which changed everything.

In 1996 I set up a web site at - initially with the idea of promoting the book.

Sun and SPARC International had kindly helped me promote the book - and they suggested I change the name to the SPARC Product Directory - because SPARC systems were now supporting PCI as well as SBus. And half the content was about servers.

Within a few weeks of setting up the new web site in the summer of 1996 it became clear to me that what customers really wanted was the directory online for free and I would have to teach myself how to sell web advertising.

And web advertising (selling ads in my own publications) has been the way I've earned my living ever since.

Today (in 2011) the SSD market - which I write about in is just as exciting as the SPARC compatible market seemed back in 1991 when I started this publishing phase of my career.
