From: vcf-midatlantic [mailto:vcf-midatlantic-bounces@lists.vintagecomputerfederation.org] On Behalf Of Herb Johnson via vcf-midatlantic Sent: Friday, May 05, 2017 5:32 PM -------------- [Kelly Leavitt:] I have my senior project from [Rutgers?] (1993) . It was a simulation of random particulate transport in groundwater written in FORTRAN. I moved this chunk of FORTRAN IV from the mainframe/mini era to the PC....It ran on my Tandy 1000A with an 8087. The vector mathematics that FORTRAN could do was amazing. ...I had offered to port the FORTRAN code to C++ at the time. The professor just laughed... He had me port this to MS FORTRAN 77 and put a C++ front end on for graphing the results. {Herb Johnson] Aha! Proof! Such things WERE done, even after the 1970's and 80's. And with personal computers. Thanks, Kelly! I'd say a Tandy 1000 with 8087 8088 is "vintage" enough. And the code was even older. Kelly, see if you can resurrect your work and show how it was done to these young'uns! ------ And my reply to Herb: I can attest that this was done. I'll look around. I saw the printed report just the other day. Quite the tome when you included the original material as an appendix. And yes, Rutgers University, College of Engineering, class of 1993. I believe, either as a second part of this project, or as an independent study, I compared the results to the 3D model presented by modflow92 (see http://gwmodel.blogspot.com/ and https://pubs.usgs.gov/fs/FS-121-97/). I was quite the groundwater modeling nerd for a few years. I look at this math now and am a little depressed in what I've forgotten. Kelly
