Title: IRX documentation on file system
Post by: CTM99 on October 11, 2010, 03:58:47 pm
I'm looking for any documentation that would describe the internal structure of IRX directories, files and data types. Also anything that might describe the organization of backup tapes. Thanks.
Chris


Title: Re: IRX documentation on file system - ITX too

I'm hoping to get similar info for ITX systems too. As I understand it, ITX was largely an outgrowth of IRX. (true?).  Any info on ITX disk directories and files as well as backup tapes would be greatly appreciated.

I used to provide the hardware to Scripps Ranch for the IRX and ITX systems.  I have sent your request to a friend of mine who worked at SR to see if he can help.

My friend is still looking, but apparently NCR threw away all of the IRX/ITX documentation.  He thought your best bet might be to find an ex-IRX customer.

If you post some hex dumps of the tapes I may can help.  I used that method to read some old century series of tape I had.
