,/* The 6128 */
Shortly afterwards, Amstrad launched the CPC6128 for the American market only, through its distributor [[Indescomp]]. The new machine sported 128k of memory and a still more sober appearance, but was otherwise nearly identical to the 664. The height of the case was greatly reduced, and the cursor keys were arranged more comfortably, both making the keyboard more ergonomically than the 464/664. Internally, the keyboard consists of two foils, although such membrane foils are relative fragile, they were more robust and reliable than the single foil used in the 664.
Despite initial denials, the machine was launched in Europe shortly afterwards, replacing the 664 for the same price - a situation which understandably irritated some of those who had recently purchased 664s. As well as the CP/M 2.2 and [[DR Logo ]] that had shipped with the DDI-1 and the CPC664, the 6128 came bundled with CP/M Plus (with the GSX graphics extension) making it an appealing all-round computer at a low price. Though the 128KB of memory could not be accessed all at once from BASIC (due to limitations of the [[Z80]]), the upper 64KB could be used readily from machine code courtesy of an upgraded Gate Array. A bundled program, [[Bankman]], provided some access from BASIC.
The presence of this extra memory and the clever design of Amstrad's CP/M Plus implementation allowed for a TPA (Transient Program Area) of 61KB, more than enough to run all CP/M software.
