MicroNotes (originally spelt μnote) were a series of short, very detailed notes on complex technical issues from DEC; primarily about hardware, but some were about software. They were mostly about QBUS PDP-11's, their bus, and its devices; but a few of the last ones were about QBUS VAX systems.

There were two different and almost totally independent sets (there is a small amount of overlap between the end of the first set, and the start of the second); an original set, and a second set, labelled "OEM MicroNotes".

Original set

This set notionally contained 111, but the re-print set (below) apparently contains ones up through 116.
