A great idea, and yes I do. I've made dumps of the ROM (an Intel 2764)
The ROM is simply labelled "IAX 3.2". I ran `strings` on it and it
confirms there is some kind of utility intended for SCSI, and there
appears to be RL01 and RL02 support, so maybe it's more like the
TDL-12 than I thought it was!

That's exactly right, yes.
