Maybe SEAL?
But there are several other DOS-Desktops including my own one
which has/had a scientific background and was coded using DJGPP.

How do you have coded this on a 8085?
Was it not a 8080/8086 and they are 8 Bit
I had an Schneider/Amstrad PC1512 (8086) with an gigantic
40 MByte Hardrive which I had to partion in two since for
one partition the Disk was TOO BIG. :-)
I was only able to get preemptiv multitasking...
...and controlled a Turning-Lathe.
