Hi Richard, Les St Clair used to make par files by year, and then I contributed some. His site is still in wayback but many of the later lists were never posted. The last backup of his site was https://web.archive.org/web/20190311231709/http://www.les-stclair.co.uk/frac... The pars I compiled start on April 12, 1997 and end on April 11, 2008. These dates were of JM "fiscal" year as it were. I uploaded the complete set of the files here to make it easier (1.7 mb). I have checked and you have some missing days here and there. You might just be able to process these if you want. You're pretty good at github I see :) https://www.interocitors.com/tmp/fractals/FTOD.zip Roger P.S. you are posting that sometimes the ID image comes out different that Fractint. Is it possible it is using a different formula? One of the biggest problems I had with Fractint was that they didn't force the formula names to be unique. In the orgform database they had "dup" lists for each letter of the alphabet.
