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 42KB61KB, more than enough to run all CP/M software.
