I only have a TL866 programmer and was not able to image the rest of the ROMs in an easy manner. I used an Arduino Mega along with
https://github.com/frisnit/Arduino-Eprom-Writer/tree/master to image the character and CP/M card ROMs. The 2708 floppy ROM looked like an easy target, with the requirement with additional -5V and +12V taken from the power supply, so I made a quick edit to the Arduino program and imaged that as well.
Each zip has a converted .bin file, all the raw reads in text form, the modified arduino source and a python script to convert the text files to the bin files. My goal was to have multiple reads with consistent data, and was successful once I used the built-in pull up resistors on the data lines. I also slowed the serial terminal down to 2400 baud earlier in my troubleshooting. All text files were logged using the tio util (
tio -b 2400 --log --log-file floppy_rom1.raw /dev/ttyACM0), edited to remove the garbage from the start and verified with the diff util.
I believe these are correct as the CP/M rom did include text.

I attempted to post the .bin files, however they are not allowed, if .zip files are not acceptable, let me know and I will upload in a more correct format.
