BASIC-80 is, as best as I'm aware, the product name of the various Microsoft BASIC implementations for 8080 and Z80. It's documented with that name in this manual which also refers to BASIC-86 which might be presumed to refer to the 8086 implementation: https://ia800708.us.archive.org/8/items/BASIC-80_MBASIC_Reference_Manual/BASIC-80_MBASIC_Reference_Manual_text.pdf As such, I think it would be reasonable to call the BASIC interpreter itself on the T "BASIC-80", although the OS is obviously more than just the included BASIC.
