The Amstrad PC1640 was introduced in 1987 as the successor to the PC1512, Amstrad's first IBM PC compatible which had launched in 1986 at just 399 pounds plus VAT. The PC1640 addressed the main limitation of its predecessor by upgrading from 512KB to 640KB of RAM and replacing the CGA-compatible graphics with an EGA-compatible chipset from Paradise Systems. In the US, it was marketed as the PC6400 through Texas-based Vidco Inc., and Schneider sold re-branded versions in Germany.
The main public test build is a Linux x86_64 host package. It starts in the WordPerfect-style full TUI by default and uses libc-hosted input/output paths rather than DOS calls. This build includes Edit-menu block commands, arrow-key submenu navigation, console mouse menu coverage, verified append/export behavior, and refreshed font attribute rendering.
