Mouse History, 1978 to 1999

I have already looked at the origins of the computer mouse in Mouse Design: 1963 to 1983, ending the story before the Apple Macintosh was introduced in January 1984, the first affordable personal computer to ship with a mouse and Graphical User Interface (GUI). This is the story of mouse development on personal computers, primarily […]

Beware the Thinkbook x10 ‘Laptop’

I don’t know if you’ve seen the ads on Facebook for a 9″ Windows 10 notebook selling for $120 and up (advertised as 80% off), but if you’re looking for a Windows notebook computer, it may not be for you. And if you’re the PC go-to guy for family and friends, you need to know […]

Apple used the new PowerPC 603 CPU in its Performa 5200 and 6200 models, both running at 75 MHz. The 603 […]

Personal Computer History: 1985-1994

Microsoft first shipped Windows 1.0 in 1985, and this DOS shell was content to run even on old 4.77 MHz PCs, albeit slowly. That was also the year Aldus invented the fourth major productivity software category – after word processing, spreadsheets, and databases – by releasing PageMaker. Desktop publishing was born, and Apple found a […]
