I think the first Pascal sold was targeted for the VAX. Also, RT11 and RSX were 'laboratory' systems and those systems were dominated by Fortran back in the day - so DEC marketing thought in those terms. True re TOPS-10. The TOP-10 Pascal compiler was ported from the one for CDC-6000 (authors: Urs Amman, Kesav Nori and may be others). The CDC version was what was described in the Pascal User Manual and Report by Jensen and Wirth. IIRC, someone at Purdue was maintaining it. I knew it well as I had added formatted IO for scalars, sets & a few more things that I forget now + I was studying it with an aim to write my own compiler. I believe this was the port: https://www.researchgate.net/publication/220846309_A_pascal_compiler_bootstrapped_on_a_DEC-System_10 [Even the portable "P4" Pascal compiler must've been derived from the same original code as I recognize its code shape and random stuff like variable names etc. p4 sources are online but I don't see the tops-10 ones]
