One of my profiles has a Z8 with a piggyback ROM. I don't know if this has the LLF firmware (no version or part number in the documentation), or if it is a version of the "system firmware" (which are part number 341-0008B? according to the documentation). This one has a part number of 341-0080 and REV.B. Does anyone recognize this?

I believe that is the 3.98 operating firmware (as opposed to LLF firmware). (Confirmed by looking at the source code in ProFile5_FW_2014-01-23.zip (http://www.bitsavers.org/pdf/apple/disk/profile/firmware/ProFile5_FW_2014-01-23.zip) -- disassembly and comments by Dr. P. Schaefer)
See page 6 of http://www.bitsavers.org/pdf/apple/disk/profile/5_Meg_Profile_HDA_Formatter_Feb83.pdf (http://www.bitsavers.org/pdf/apple/disk/profile/5_Meg_Profile_HDA_Formatter_Feb83.pdf)
Some other variants of the ProFile firmware (thanks Al!): http://www.bitsavers.org/pdf/apple/disk/profile/firmware/ (http://www.bitsavers.org/pdf/apple/disk/profile/firmware/)

I don't see the exact part number of page 5 of the 5_Meg_Profile_HDA_Formatter_Feb83.pdf, but it is clearly at the top of profile5RW.asm - thanks for the pointer! It will be interesting to compare profile5RW.asm with profile5LLF.asm.
I'm pretty sure I've seen the part and procedure for burning a new EPROM here or on another forum, now to find it again...

It is likely you have a ProFile that was never updated. Good for you - it means you can LLF by just swapping the ROM!
I have had trouble formatting ProFiles with BLU. If it encounters any bad sectors it does not know what to do with the return code and gives up.

I think once I find a LLF ROM, I'll do the formatting with an Apple III.

Bitsavers has the bits. Programing with a MiniPro USB programmer works fine!

So this one? https://www.amazon.com/TL866CS-Universal-Programmer-Adapters-Extractor/dp/B01A6MPR4A
Lame that it only works with Windows, but I do have an old Mac mini running bootcamp...

So this one?
The pictures don't show the actual programmer, just adapters. May be an error in the listing, or misleading; I'd look for a different listing.
FYI, they aren't made any more, so you're probably getting an unauthorized clone (up to you to decide if that's ok).

I use my TL866II+ with Linux courtesy of the minipro (https://gitlab.com/DavidGriffith/minipro) utility.

Yup, I use it on my Mac with this utility.
*Sometimes it stops working and I need to reinstall it from Homebrew. Not sure why.
