Even my old Heathkit ET-3100 Electronics Trainer
I have two of those and a 3200 I think. I wish the breadboards had power rails. I taped one to one of the ET-3100's after I fixed a ripple problem on the power supplies.

Yup, the old ceramic ones didn't either. They used a separate 2-row one that was a bit shorter. Even with the power rails on the board you still have to jumper power into the circuit though. Just a shorter jump.
