It may seem to some vintage computer newcomers that the plethora of numbers in the designation of early pc CPU and model types is just too confusing. After all isnt Pentium, Pentium III and IV self explanatory? After all what do the numbers and terms 8088, 8086, 286, 286 and 486 represent anyway and what is the difference among them all?
To begin with the 8088 is the oldest of the early PC central Processing Unit (CPU) variant models. which means a rectangular case with two rows of 20 pins. DIP stands for Dual In-Line Package. Older 80800 CPUs are called 8088-2. As they can only run at lower speeds (believe it not 5 MHz or slower compared to a now 4000 MHz computer). The faster models the Turbo PC/XT clones ran at faster rates of 6.6, 7.16 or even 8.0 MHz. IBM function with the PC was so shut the market down to protect their lucrative central core of their business- mainframe computers. You can imagine upper brass at IBM was not too thrilled at the competitive upkill from Clone manufacturers such as Compaq or later Dell. By the way the 8088 had the equivalent of approximately 27,000 transistors.
