Yes, I have been studying the SA-1100 and SA-1110 manuals as well as the Cirrus EP93xx documentation. They all are quite similar, yet not the same. A lot of the information can be reused, the basic though process is the same, but the details are different. The register addresses are different and can't always be mapped 1 to 1. The bits within the registers are scrambled, missing, added, inverted, etc. . It's all those little mean things that make programming the emulator more of an experiment in patience than a logic deduction. ;-)
And it would be oh so cool if we had these docs ;-D
