First IBM PC (Personal Computer) was IBM model number5150, which was introduced on August 12, 1981.IBM's first electronic digital computer was the 701 Defense Calculator, introduced in 1952.IBM's first computer was the Harvard Mark I, in 1942, but it was electromechanical.
2ng generation. It used transistors and magnetic core memory
Depends on how you want them to be compatible.
Varied widely depending on requirements of the computer.The IBM 1620 a small scientific computer had from 1500 to 5000 transistors in the CPU depending on options included.The IBM 1401 a small business computer had about 10000 transistors in its CPU.The IBM 7030 Stretch a supercomputer had about 170000 transistors.The CDC 6600 a supercomputer had about 384000 transistors.The CDC 7600 a supercomputer had about 2900000 transistors.You can compare this to first generation computers, the largest of which the IBM AN/FSQ-7 had about 50000 vacuum tubes.You can compare this to modern multicore microprocessor based computers, a typical one of which has a couple hundred billion transistors per processor core integrated on one chip.
The IBM 701, their first computer available for sale, had 36 bits per word. This word size was used on all their 700 and 7000 series binary scientific computers.
