The QL Service Manual is the official guide to fault diagnosis and repair of the Sinclair QL home computer.


It was first published in 1985 and went through at least 3 revisions and contains circuit diagrams, fault diagnosis, system test, parts list and disassembly/assembly instructions for the QL.


Unfortunately, it only contains diagrams and parts lists for the issue 5 and issue 6 motherboards.


A copy of the issue 3 version (November 1985) can be downloaded (as a rather large PDF) from [[ftp://ftp.worldofspectrum.org/pub/sinclair/technical-docs/QL_ServiceManual.pdf|The world of Spectrum]]
