Did I get an RL01 pack instead of RL02?

YEs, the DEC packs are 40 sectors. 8 sectors (you're right about the 
double slot being the index pulse, this was used on many other drives, 
including the RK05, and indeed hard-sectored floppies) sounds rather too 
few, but anyway.

I beelive it's also used to get the servo system to start looking for the 
servo bursts.

I very much dout it, ut it would eb a fun project to try...
