Preface

This Technical Reference Manual is intended primarily to assist writers of software for the Amstrad PC1512, although in conjunction with the PC1512 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 with Floppy Disk, Serial and Parallel Adapters.

The information contained herein is largely unique to this document, with the exception of parts of Appendices 1, 2 & 3 which expand on the information contained in the PC1512 User Instructions and the Microsoft MSDOS Reference Manual.

Whilst the PC1512 implements a superset of the Industry Standard, this manual makes no attempt to identify those areas of the PC1512 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.
