which processor was released in the first ibm pc
IBM Personal Computer The original PC's maximum memory using IBM parts was 256 kB, achievable through the installation of 64 kB on the motherboard and three 64 kB expansion cards. The processor was an Intel 8088 running at 4.77 MHz, 4/3 the standard NTSC color burst frequency of 315/88 = 3.57954[a] MHz. (In early units, the Intel 8088 used was a 1978 version, later were 1978/81/2 versions of the Intel chip; second-sourced AMDs were used after 1983)[citation needed]. Some owners replaced the 8088 with an NEC V20 for a slight increase in processing speed and support for real mode 80186 instructions. The V20 gained its speed increase through the use of a hardware multiplier which the 8088 lacked. An Intel 8087 coprocessor could also be added for hardware floating-point arithmetic.
Home computer The very first home computer was the Compucolor by Compucolor Corporation in 1976, soon followed by the Compucolor II which was made by Intelligent Systems Corp. They used the 8080 but otherwise sported very advanced features, including RAM starting at 8 KB, expandable up to 32 KB, 64 column by 32 line color CRT display, a professional keyboard, an enhanced BASIC interpreter , and a built-in floppy disk drive. It only sold a few thousand units, however, and the company went bust not long after.
