Lately I’ve been getting more frequent “do you know where I can get?” request for new floppy disks with the hard disk operating system software. Mackie doesn’t sell ’em (never did) and nobody seems to have taken on the job of being a supplier, so you’ll have to make your own. To save myself a lot of re-typing, I’ve added a short article to the Mackie HDR page. If you have an HDR or MDR24/96, you’ll eventually need to replace the software.
Be prepared. Get what you need now while you still can.
