During the 2058 days (August 12, 1981 to April 1, 1987) in which the IBM PC was on the market, there were a surprising number of configurations available for the machine. Although its mostly for historical interest, they are as follows :
Description of the Columns :
Model - IBM's term for the configurations
83-key - Did the system come with an 83-key keyboard? Systems that did not were typically designed to emulate something else.
RAM - Amount of RAM included on the motherboard
Floppy - The 160KB drive was single sided and could do 180KB. The 360KB drive could do all those and 320KB. All models that came with disk drives came with a diskette adapter.
Motherboard - Motherboard Type
The Model 1 is the most basic configuration of any PC. No floppy and virtually no RAM.
The Model 176 is as fully featured as it got as a stock IBM machine.
