6128 cpc to 6128 cpc plus possible or not ???

Technically you set a register to a too short value, and you must set another one before to enable the problem. Sceners in France did some "tests" with that years ago.

Hmmm. I guess if R0=0 and R1=1 then DE set and reset would both trigger at the same time so that flip-flop would be metastable, which could lead to a high current draw. I still can't realistically see it damaging the chip though.
