I'll just send the CP/M disk along with the others, let you copy it and send
it back. I'm not a CP/M guy. Don't you also have to build the kernel for
your memory and I/O configuration? Anyway, it will be easier for you then
me...
I was able to reset the stepping times. I just didn't want to pull the
write-protect tab off, so I SDUP'ed it and used the copy. I only found out
about the stepping times by playing a little with the commands on the disk
to see what they did. I remember the first H17 disks which were the
Wangco's. They could step at 6ms! I like the REDUCDIR command. I wrote
one way back in '79 to do just that. Getting back something like 10
allocation units was great!

Walter, no, it won't do CP/M. It expects to find all of the volume
number/label foo. If you need a CP/M boot disk with copier, let me know and
I'll one along.

Argh. The things we forget. Sorry, my bad. Were you able to reset the
step rate, or shall I send you one of those as well?
