I do not remember these RL02 drives being this heavy.....


On a slightly more interesting note it looks like I only have RL02 
drives (3) and do not have any RL01 drives. That could be a problem if I 
want to re-load Cobol 81 onto this RSTS/E system. However the RL02's 
*should* allow me to reboot RSX11M 4.2 and repair the instance of RSX11M 
4.0 that is on my Fujitsu drive (damaged).

Likewise my RT11 images might be on RL01. However I do have the Plessey 
disk drive that emulated 4 RK05's on a fixed platter and a removable 
platter disk subsystem (which uses disks that look like RL01's but are 
*NOT* RL01's) and I *think* I had either RT11 with MUBASIC or a really 
weird Gen of RSX11M and RT11. Though I'm not sure if RSX11M would run on 
RK05's as boot devices (2.5mb of space)

The dig continues. This weekend I'll see if I can fire a RL02 up.
