Les St Clair used to make par files by year, and then I contributed some.
Oh sweet! I will go through these. It looks like you didn't keep Jim's little essays for some of them. Oh well, the pars/frms are better than nothing :)
His site is still in wayback but many of the later lists were never posted. The last backup of his site was

Oh, lots of archived goodies there, thanks. Some of these programs were in danger of being lost to the winds of time. I have uploaded tierazon and flarium to github and a couple others.
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.
Yes, some days are missing because they didn't render in xfractint, but I believe I do have the PAR files on github for those days.
This is very helpful indeed, thank you!
P.S. you are posting that sometimes the ID image comes out different that Fractint. Is it possible it is using a different formula?
When I render Jim's FOTD as an image, I always use the inline formula as given in his PAR file. However, there are two variants of the formula parser/interpreter. There is the assembly language verison used by the DOS code and there is the C language version used by everything else. Where they diverge, I assume the bug is in the C code. Many of those that fail to render similar to fractint are using the exponentiation (^) operator in the formula. Sometimes use of fn[1-4] fails in the C formula code, but if you inline the actual function used into the formula, then it renders correctly.
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.
Oh, that's good to know about the duplicate name problem. I have some ideas about improving management and sharing of these definitions as a longer term plan. -- Richard -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Terminals Wiki <http://terminals-wiki.org> The Computer Graphics Museum <http://ComputerGraphicsMuseum.org> Legalize Adulthood!
