This Technical Reference Manual is intended primarily to assist writers of software for the Amstrad PPC, although in conjunction with the PPC Service Manual it will be of interest to designers of add-on hardware.

It is assumed that the reader has a working knowledge of the Industry Standard architecture comprising of an 8086 (or 8088) with DMA, PIT, RTC and Interrupt Controller support chips; plus Colour Graphics Adapter (or Monochrome Graphics Adapter) with Floppy Disk, Serial and Parallel Adapters.

The information contained herein is largely unique to this document, with the exception of parts of the appendices which expand on the information contained in the PPC User Instructions and the Microsoft MSDOS Reference Manual.

Whilst the PPC implements a superset of the Industry Standard, this manual makes no attempt to identify those areas of the PPC specification which exceed the Industry Standard. Users should, therefore, exercise caution when writing software for a range of manufacturers' PCs and only use the "Lowest Common Denominator" facilities if simple portability is required.

Please note, that communications regulations do not allow the release of technical information relating to the circuitry or construction of the PC2000 modem.
