The success of the VAX family of computers transformed DEC into the second-largest computer company in the world, as VAX systems became the de facto standard computing system for industry, the sciences, engineering, and research. The first commercially advertised US computer based on a microprocessor the Scelbi has 4 KB of internal memory and a cassette tape interface, as well as Teletype and oscilloscope interfaces. Scelbi aimed the 8H, available both in kit form and fully assembled, at scientific, electronic, and biological applications.
The C64, as it is better known, sells for $595, comes with 64 KB of RAM and features impressive graphics. Thousands of software titles were released over the lifespan of the C64 and by the time it was discontinued in 1993, it had sold more than 22 million units.

Wang sold the 2200 primarily through Value Added Resellers, who added special software to solve specific customer problems. The 2200 used a built-in CRT, cassette tape for storage, and ran the programming language BASIC. The first large commercial computers to use integrated circuits, RCA highlights the IC’s advantage over IBM’s custom SLT modules. Spectra systems were marketed on the basis of their compatibility with the IBM System/360 series of computer since it implemented the IBM 360 instruction set and could run most IBM software with little or no modification.
Significantly more men, 22%, than women, 17%, said they were “very confident” they could do this. Similarly, in November 2004, we asked if people had computer networks linking their computers together at home. Again, significantly more women, 13%, than men 4%, said they did not know. And again, more men, 54%, than women, 45%, said they did have home networks. More women than men asked a friend or family member or colleague for help.
