Thanks! I started on a ROMP emulator in Swift using only the docs and = 6150 IPL ROM on Bitsavers many months ago, then got sidetracked with = work. Maybe I=E2=80=99ll pick that back up again, especially if = there=E2=80=99s more/better documentation available now. One thing I found was that among the first few instructions in the IPL = ROM, you immediately hit undocumented bits. I=E2=80=99m pretty sure = they=E2=80=99re for resetting the two different floating-point = accelerators. -- Chris
