What was the price of the IBM PC in 1986?
1986: April- IBM announces the IBM PC Convertible, 80C88-based, 256K RAM, and two 720K floppy disks, for US$2000. 1986: April- IBM discontinues the IBM Portable PC. 1986: September- IBM announces the IBM PC-XT Model 286, with 640KB RAM, 1.2MB floppy drive, 20MB hard drive, serial/parallel ports, and keyboard for US$4000.
What was the basic configuration of the IBM Personal Computer?
The IBM Personal Computer (“PC”) was not as powerful as many of the other personal computers it was competing against at the time of its release. The simplest configuration has only 16K on-board RAM and uses an audio cassette to load and save data – the floppy drive was optional, and a hard drive was not suported.
