Sorry I missed your reply until now...
I was showing a plane I have for sale (have to pay for my new Lotus!).
The one bootable disk I have appears to be soft-sectored.
How can I get O/S software for a soft-sectored H89?
Can you still buy 360K media?

Hi Bob
There is a group at www.sebhc.org that you should joint. They have a
reasonable collection of software. They use a image transfer tool that I
wrote.
You won't find much on manuals. There is someone that bought the copyright
to all of the HeathKit stuff and watches it closely for infringment.
Software is a different story, being that he was a Ham and mainly
interested
in manuals.
It also sounds like you have a hard sectored drive( look at the disk for
11
index holes ). I've converted an old SA400 frame into a punch for hard
sectored
disk. One uses 360K disk. If you are interrested in borrowing, let me
know.
I have several manuals as well.
I might be in your area today or sometime soon.

I've just come across a new vintage system.
I've been given a Heathkit H-89 computer with some documentation and one
bootable diskette.
Its booting HDOS, but I don't have any HDOS specific documentation, just
the 'Operation' and
assembly manuals (the 'Operation' manual is really theory of operation
material).
Does anyone have the ability to make a set of 'distribution' HDOS disks
(100K floppy)?
Is CP/M also available, or the Heathkit diagnostics disk?
I've not been able to find much HDOS documentation on-line, does anyone
have pointers?
