[sgroup] Intro, DJ-70mkii

Hello List, I just recently joined, and appreciate the presence of this list and the archives so much. I started into the Roland sampler world with a 2nd-hand S-750 two years ago. Later I picked up an S-760. Last week I found a DJ-70mkii. If anyone can help me get the operating system upgraded on the DJ-70mkii, I would be very grateful. I saw on the net that the DJ-70 could boot from an updated operating system if you had the proper boot floppy in the drive on power-up. I can't find any such floppy anywhere. Haven't called Roland US to see if they have the EPROMs in stock still, would that be worth a shot? I currently have v1.00 of the OS, and it seems like it can read Zip and Jaz drives fine, but I'm kinda scared of getting too comfortable and then losing some work. Thanks Tim
