On Hardware 2: Playing cards

One of the massive changes during the PC era has been that motherboards now include all the functionality that once required a handful of plug-in cards. Apart from a video card or two I’ve not bought a card since 2001. But before then:
1989: An early purchase was an I/O card allowing me to run two printers from the same PC. Like all cards from the era, installation was preceded by careful reading of an instruction leaflet and setting numerous jumpers to give the required functionality. Hooray for Plug and Play.
1991: A Compaticard, £182, allowing the same PC to have a 5¼” 360K floppy drive in addition to the default 5¼” 1.2MB and 3½” 1.44MB drives. 1.2MB drives would read 360K disks, but to write a disk that could be read on a 360K drive you needed to use a virgin disk. Adding a 360K drive got over this. There was a time when we bought 360K floppy disks by the thousand. Now we send out a few CDs each week; everyone else downloads. A Promise hard disk cache controller followed in 1993, claimed to make things work a lot faster, followed by several more HD controller cards as technology changed: EIDE in 1995, then PCI
1992: My first network: two PCs linked with 10Base-2 coax cable. Two network cards cost £202, and the networking software, Netware Lite, then Lantastic, another £50 or so per PC. Now you can link multiple home PCs for next to nothing – Windows provides the software, the motherboard the hardware.
1992 also saw my first modem, £41 – dial-up of course – to connect to CompuServe. Speed not recorded but it was replaced by an Intel 14.4 faxmodem in 1994 and a 33.6 faxmodem in 1996 – that’s 33,600 bits per second; now I am on fibre, nominal download speed 100,000,000 bits per second, nearly 3,000 times as fast. And thanks to bloat some websites still work at dial-up speed!
Video cards: 1991 saw my first recorded separate video card purchase (of course my ready-built systems came with HD, video and basic I/O cards), a Trident VGA for £60. For my sort of programming, there’s no need for a high performance video card, save the one I bought for 4K testing last year. Of the video cards bought over the years the outliers were a pair of Diamond Viper Weitek cards bought in 1996 when I was an OS/2 user – as I recall these cards had issues with Windows so were sold off cheaply (£107) but worked brilliantly with OS/2. When I moved to Windows, a Matrox Millennium, then Matrox Productiva AGP and ATI All-in-Wonder cards took over
And somewhere during this decade was a sound card, bought as a personal purchase, another function now handled by even the cheapest motherboard.
