I sent you a PM over 2 weeks ago but for some reason never left my outbox, so copying it below:
If you need the MZ-80B IPL source, it is stored here
https://github.com/pdsmart/tranZPUter/b ... 0B_IPL.asm
----------------
All the files listed below are on well known websites such as original.sharpmz.org which Ive just collated for my machine, I can make a tarball up for you if they are of use.
The DAT files have no MZF header so you would need to place a 128 byte header at the beginning before writing to a tape, ie something like this:
0 01 43 50 4d 32 32 33 52 46 53 0d 0d 0d 0d 0d 0d 0d 0d 00 1c 00 a0 00 b6 06 10 3a f8 ef 10 fb 3e .CPM223RFS................:....>

60 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................................
80
Details of the header are here:

The MZT files already have a header so just need to be written to a tape, again look at the original.sharpmz.org website as they have tools for making tapes from data files.
The MTI files are in a wave format ready for writing to cassette, so probably the tools at original.sharpmz.org can handle them.
The DSK files are disk images for use with a floppy emulator or written to a real floppy disk.
I havent played much with my MZ-80B, too busy with my other machines but eventually will get around to it.
The files I have are:
