Issues before June, 1992, have file names starting with tuug, rather than muug, reflecting the former name of the Manitoba UNIX User Group. The file tapes.pdf contains a tutorial on magnetic tape formats, taken from the January 1992 issue of the newsletter.

The PDF files for some issues were produced with OmniPage Deluxe v12 OCR software, starting with scanned images of paper copies of the newsletters. These are primarily for older issues, where the electronic copies were lost. These PDF files are larger in size, and of lower image quality, than the rest. The OPD source files corresponding these can be found in the ../opd/ subdirectory. PageMaker source and PS files are not available for these issues.
