Those would have fit a Terak system for UCSD Pascal. I’ve still got a

anyone know what system these floppies are for?

Some are labeled "MRX", "CP/M", "Isis", "Chip-?","PROM?", I do not see
any that are labeled "Terak", "UCSD", or "Pascal"
At least some of them say, "single-sided, soft-sectored double
density", some say "double sided", so they would physically work in a
lot of stuff if reformatted. But imaging is important, as they MIGHT
have something significant on them. "Bubble memory files"?
They sold for $59 to somebody with 8000 feedbacks.
There are three that appear to be Intel MDS diskettes. The ones marked
ISIS V4.3 is, as I remember, the last version of ISIS-II that Intel
released. ASM51 and RL51 appear to be assembler and relocater for the
8051 series of microcontroller. And ICE51 was the in-circuit emulator
software for the 8051 series as well. None of the other labels mean
anything to me, but those three are likely for the Intel Development
System. Those systems could have single-sided, single-density FM
drives, and/or single-sided double-density M2FM.
The Intel MDS could, of course, run CP/M-80. So many of those other
diskettes could have CP/M software/files and still be used on the Intel MDS.
