North Star Hard Disk HD-18 Technical Manual

[Jack Strangio]

Hi Guys,

On a very, very, very slim off-chance there might be somebody here who has
access to the North Star Technical manual for the HD-18 Hard Disk System.
This was a 14-inch(!) hard drive that was used for a year or two around 1978
before that niche was taken over by the ST-506 Series 5-inch hard drives.

The actual hard drive used was a Century Data Marksman drive. I have the
Technical mamuals for that. I'm looking for the Technical Manual for the
North Star HD-18 Controller as used in the North Star Horizon.

Thanks in advance.

Regards,

Jack

Hi Jonathon,

Thanks for that. I have emailed Herb asking if that particular User's manual
contains the information that I'm seeking from the Technical manual.

Hoping for the best.

Thanks.
