Sinclair PC 200

Historia

In late 1988 Amstrad created a desktop computer based on the PPC design, intended for the home market. The LCD was replaced by an RF modulator to display CGA video on a domestic television, and the keyboard and system unit were combined in an integrated case similar to the original Atari ST or the Amiga 500. The second floppy drive bay was replaced by two ISA slots, though the design of the case was such that any cards fitted would protrude from the top of the computer. The PC200 had a black case and Sinclair branding, while the PC20 was white and branded Amstrad; the two were otherwise identical. In addition to MS-DOS 3.3 and Organizer, the PC20/PC200 was supplied with GEM and four CGA-compatible games. The graphical capabilities (CGA) and sound output (PC speaker) were greatly inferior compared to other home computers of the time. Consequently, the PC20/PC200 was not a commercial success. Although the PC20/PC200 does not support todays floppy disk drives through the built-in FDD connector, it uses a compatible floppy disk controller (Zilog Z765a) that can work after modification of the FDD connector, though only with 720k disks Ficha Técnica:
