Racore Sidecar

Is the sidecar the same on the Racore Drive II (model 1500) and Racore Drive II with DMA (model 1501). I know the Racore Drive II with DMA comes with a floppy controller and different cables but is that the only difference?

The DMA chip is on the sidecar, so yes, they are different.
(I'm not sure if it is the same circuit board with just an extra chip populated or if the board itself is different.)

After some further research it would appear it is the same circuit board. The difference being with the DMA version having the DMA chip, different jumper settings and removal of a terminating resister. Racore sold a kit that allowed a user to upgrade the Model 1500 to the Model 1501. They also put out instructions on how to disable DMA in the model 1501 in the event DMA was problematic. The other thing I found out is the DMA only works with the internal Racore Memory.
