Editing IBM 5120 (section)

== Service Documents ==

Both IBM service documents for the 5120 are '''hosted on this wiki''':

* [[IBM 5120 Maintenance Information Manual]] — '''SY34-0192-0''', December 1979. The CE service manual. The scan has no text layer, so it cannot be searched; read it by eye.<ref name="mim5120" />
* [[IBM 5120 Computing System Logic Manual]] — '''SY34-0193-0''', December 1979. Gate-level logic diagrams and the DC power distribution sheets.<ref name="logic5120" />
* '''GH30-0232-1''' — Joint 5110 / 5120 Bibliography, September 1980 — also lists 5120 publications.

The 5120 documentation set on Bitsavers is thinner than the 5110's — many user-facing manuals (APL, BASIC) for the 5120 are the 5110 manuals because the language ROMs are essentially the same. Use the 5110 references where applicable.
