Floppy disks wanted - 5" hard sector

Hi I've made a punch setup that seems to work. I used the frame of an old SA400 ( broken before I got it ). I can punch the needed holes but it is not a high speed production system. I figure for my time, a box of ten for $10 is a lot cheaper than my rates. Still, for my uses, punching them myself has personal satisfaction. If anyone is interested, I do have bootstrapping routines for H8/H89 Heathkit machines so a person can get their system up and running without a preformatted disk ( it does need the 10 extra holes ). One can the download HDOS through the serial port onto a fresh disk. The Poly 8813/10 also use hard sectored disk. I expect to do some work on a similar routines for these. Right now, I can transfer files but it does take a boot disk to get started. I have a couple of Northstar machines but haven't had the time to play with them. They are on my list. Dwight
