Super cool and thanks! It even lists the 760ED in the readme. The installer fails part way but I was able to copy all of the files and then I added the same lines from my IBM 755c. That still didn't work at first but one of the files named IBMDSS01.SYS had a S04 and a S14.SYS. I tried each of those and the S14 worked! I got some complaints that the card services was way out of date but everything still worked.
I think having the IBMDSS14.SYS is the key. I might retry the newer IBM 755c card services and use that S14 version to see if it works without any warnings.
