As I understand it, there were intitially 2 'packaged' systems. One had the CPU with an RL02 under it for the 
OS disk and an RL02 on top for the user disk. The other had an R80 in place of the bottom RL02. 
If you had the first version, the bottom RL02 slid out to change the pack.

That's what they did. There was a third (later) packaged system with the CPU, an R80 under it and a front
loading (Cipher F880) magtape on top. That is what mine started out as.

I am not sure if I got the top panel but if I did it is no longer on the rack...
