Nov 11, 2026, 11:29 PM@gloriouscow cc: @steve for that doctoral thesis from the 80s that most softFPUs use as a test suite that I can never remember the name of.

Also operational quirks in addition to arithmetic results.
These tests would also capture all bus cycles, so people can study how the FPU handshaking worked across generations.
I should probably track down that test suite and see if i can translate it directly to SSTs
mirthmirth@mastodon.sdf.orgNov 12, 2026, 1:37 AM@gloriouscow @cr1901 @steve I realize it's out of scope for this project but if someone did structurally the same thing but for 68881 and descendants I would also be excited to see that exist (I do not have the expertise myself).
