Looking for Heath H89 software and some advice

They say it will take 3-4 weeks, but were willing to sell me some for $1 a piece, or cheaper for quantities of 5000 or more. :) Here's their web address: http://www.athana.com On the subject of the nonbooting HDOS disks, I don't think there's anything wrong with the machine (I have two separate machines exhibiting the same behavior, after all) -- I think the disks are just very borderline. I adjusted the rotational speed on one of the H89's (it should be 200 according to my Heath manual) and then was able to get one of the HDOS disks to almost boot. But part way through the boot sequence it gets some unpleasant error and complains. So I suspect that if I had a fresh copy of an HDOS disk it would boot. Still don't know why the CP/M disks fared better, but perhaps they're a bit younger... Dave
