Okay, I've had a bit of time in front of the machine to repro this and take a look. What I actually see is: R0 177770 R1 0 R2 0 R3 0 R4 0 R5 34 R6 141774 PC 000254 (remember, for the last, this will have been after taking a trap to 250, where I have the usual "BR .+2; HALT" catcher installed) Also, memory at 060 (PA:164060) is all zeros as far as the eye can see... I have a bit of water on the basement floor right now after the recent rains here, which is complicating setup of the LA. There's a big puddle where I normally place it...
