Yes, I had disassembled quite a bit of the slot roms. A lot of the motherboard ROM regularly entered the slot 3 ROM for 80 column work, since not all of the code could fit in where the cassette routines were. The slot 1 and 2 ROMS had a few entry points that dealt with serial devices. If you were to hold down ctrl-P on startup, you would enter the serial device control panel. At least that worked on the 128EX and 128 EX/2. Not sure about the original 128.
AFAIK, there's a single physical EPROM in the unit (reached through the bottom access plate that covers the Slot 5 & 7 internal-external switches). Where are the slot pages and respective C800 images located in the image? I assume they're doing a bit of decoding to present the expected picture.
