Who else used (uses?) SPIM for this?

https://pages.cs.wisc.edu/~larus/spim.html ... and apparently its being kept up to date https://spimsimulator.sourceforge.net with new builds about every other year.

(I took the class from Professor Miller in... '92... Operating systems in... '94? 95? was from Professor Larus)

A first year course at UNSW, COMP1521[1] teaches MIPS and uses QtSPIM. Far from dead, a package is maintained on the AUR[2].

My university in Portugal did (UNL/FCT), similar timeframe.

CS61C uses RISC-V now.

Oh, cool! I remember hearing a lot about RISC-V back then, and it's also from Berkeley, so makes sense.

Makes sense. Isn't MIPS like a commercial variant of RISC-I?

IIRC, Berkeley RISC was mainly SPARC, although it was also the AMD 29k.

Stanford was MIPS.

Rochester Institute of Technology had MIPS in their CSCI-250 Concepts of Computer Systems class. I remember debugging my final project for the semester being a bit of a nightmare because it was a much larger MIPS assembly project, and debugging it used gdb if I remember correctly..

Not sure if they still use it as I graduated from there back in 2020

This was true of University of Maryland back in 2015 when I was there…
