Known differences between SimH, 11/70, and w11a
SimH: vector flow that sets tbit does not trap
On an 11/70 and on a J11, a vector flow loading a new PS with tbit=1 ends
with a tbit trap.
On SimH, a vector flow loading a new PS with tbit=1 does not tbit trap.
Confirmed deficiency, will be fixed.
The w11 implements the 11/70 behavior, the corresponding tests are skipped when executed on SimH (see cpu_details.mac test A4.4 part 9,10).
Tested with SimH V3.12-3.
