[Coco] Cutting WP notch on DSDD disks?

[Jim Cox]

After so many false starts I am finally getting started 
withe the CoCo again and have a CoCo3, Drives, and Monitor 
set up.

Last night, with the help of Bob D and Rodney (and Roger 
giving me tips on formatting :) I was able to test my 
drives as well as the drive I am sending to Mary.  

One problem I ran into is that the blank disks that I 
purchased in buld with Carl Boll (I think) do not have a 
Write Protect Notch, so I was unable to test with those 
disks.  Since there are 500 of these disk, and I'd like to 
know if there is an easy way to puch the Write Protect 
notch in them?

Bob suggested a hole punch, is there anything else out 
there that can do the job.  I tried using sissors, but it 
was an ugly site.

Thanks!

Jim
