I've been looking into the tools of Research UNIX versions 7 and 8 and 4.2BSD, as well as other old utilities that we may still find useful. So, with the sources at hand of most such programs, I've started porting some to native Plan 9. As the ports are completed, I'll make them available in /n/sources/contrib/akumar/^(cmd relic). Only a couple exist so far; diff(1) files are included for comparison - I've tried to retain the original coding style and logic. See the respective NOTES files for extraneous comments in the style of annotations, and some background information on the tools.
If there are any such tools you would find useful and would like to see ported to Plan 9, let me know (perhaps offline). Thanks to Russ Cox's help and Prof. Kenji Okamoto's code, I was able to get my Post- script illiterate printer, an HP OfficeJet 5610, to print with Plan 9. For anyone else requiring IJS support in gs(1) (hpijs binary included), the necessary files are in /n/sources/contrib/akumar/gs -- see the NOTES file therein for documentation and references. Best, ak
