Section under construction, but feel free to see gallery of recently acquired PCs here.

The first IBM PCs, released in 1981, had poor graphics capability, simple beeper and not outstanding Intel 8088 CPU. It had (usually two) 160kB floppy disk drives and could run ported CP/M or PC-DOS with their 128-640kB of RAM. What made them popular was their open architecture - the only thing manufacturer had to buy was IBM BIOS license. Later other companies started to make their own BIOS versions compatible with IBM, sometimes much more configurable than original one. In 1980s and 1990s many companies made their own IBM-compatible (or almost compatible) computers and sold under different names.
PC became popular in offices, homes and industrial systems. Its architecture oriented around ISA bus was expandable and many expansions have been developed. Early PCs were usually more or less software-compatible with IBM PC, but sometimes hardware was much different than in original.
Today (2015) PCs are still used and there is a big chance that you are reading this page using one. Unfortunately ther are not so free anymore, as proprietary, undocumented chipsets are used and simple, assembly-code BIOS (there are even open-source BIOSes for PC) has been replaced by EFI - a security problem at the hardware level. To run some operating systems on the newest PC platforms, systems must be confirmed by commercial organizations, this is called "Secure boot" (but much better name is "protection money"). PC started as open architecture, but will end as proprietary one.

Here you can see that there are many ways to build PC, and not all PCs had ISA. You can also see interesting expansions and devices for PCs.
