The Memotech MTX Series

The Memotech Library

Technical Data for the MTX Series

Application & Technical Notes, Tutorials


As I have worked on my Memotech kit, I have gathered quite a lot of technical information such as component datasheets and manufacturer's data books. I have made them available via these pages as they may be useful for others and, given their age, some are not too easy to find.

My interest in this data relates to its use in the Memotech MTX series of computers and related hardware, so the most useful information dates from, say, between 1983 and 1987. This page contains various tutorials and articles from academic sources and manufacturer's websites which discuss technology from the period and are almost certainly of little interest if you are looking at today's technology. If you are looking for up to date information, the publications here are likely not of use to you.

Much of this information comes from long defunct publications or relates to obsolete technology, I don't imagine that the copyright holders, are vaguely interested in these pages, but if anyone has issues with me making this information available, let me know and I will remove the offending item(s).
