8M2 is Euro notation where the magnitude replaces the decimal.  Hence 
8M2 = 8.2Mohms, 2k2 = 2.2 kohm, etc.

The "cassette jacks" are right angle circular DIN MIDI connectors, 
something like Digi-Key 275-1022-ND.  Not sure why they called out 8 
pins, but hey.  You may or may not have trouble getting it to fit on the 
PCB land pattern and rear holes.  You could always consider using a 
panel-mount version instead and flying lead to the board.

You should be able to find subs for any of your parts at an online 
retailer such as Digi-Key or Mouser.

I am assuming the SDS1000 is the same circuit boards without these parts 
stuffed.  Where they go should be fairly self-evident once you get the 
box open.  They are clustered around the holes on the back panel where 
the jacks go.

I do not remember the midi notes offhand, but I do know that they do not 
line up with the typical general midi assignments on my akai MPC.
