MSDOS

Manufactured by Fujitsu from early 1989 to 1997, FM Towns is a Japanese multimedia computer based on x86 Intel CPUs and a CD-ROM drive. The computer offered a 24-bit color palette, hardware graphics, and sound capabilities similar to arcade systems.

Released in August 1981, the IBM Personal Computer was IBM’s first microcomputer and the hardware platform that created the standard for PC compatibles. The IBM PC used an open architecture and the PC-DOS from Microsoft. Later, in 1984, IBM released the considerably improved IBM AT based on 80286 and a 16-bit AT bus.
