Cdc (hawk)

[Marty]

Hi All;
Can or Could a CDC (HAWK, Can't remember its number..) Disk Drive, (5 Mb fixed, and 5Mb removeable), be interfaced to a Dec 11/XX, either thru a controller for the CDC or thru an RL11 Controller, with a special interface to tie the two together ?? I have the Drive and a RL11 (7762) Controller ..
THANK YOU Marty

Marty,

That drive probably uses an SMD interface, which is not compatable with RL11. I actually have one more "modern" CDC hard disk that uses SMD and I have a Qbus Emulex SMD controller for it that looks like a MSCP device. So, to use that Hawk, you will need an SMD controller.

Hi All;
Lou, Thank You, I have two different interfaces for this drive, One is (I think) You are right, for an SMD From an old TI 990 System and the other one came from an old Wang 8080 Word Processor System and Don't know what that interface is called, But I have Both for the Drive.. I thought that the one from the Wang system, might be able to interface to the Rl11..
THANK YOU Marty

Random information that may or may not be helpful:

If the Hawk is the drive I think I remember, a top loader in a waist-high free-standing cabinet, we serviced an inventory system for a furniture company using a DG Nova cpu and if my memory is to be trusted the disk was hooked to a System Industries controller. The SI controller was in it's own chassis in the computer rack cabinet. I don't think the disk interface was an SMD interface, but I could be wrong (easily ).

We also has some SI controllers on DEC machines, I don't recall if they connected to the Hawk drives though. I only remember the one DG based system that used the 5/10 mb hawk drive.

Doug, you are probably right.

I was thinking of a 9762/9766 which were much newer and much higher capacity, but were SMD (acccording to the sales literature I found in the piles here.)

I stumbled across the Hawk maintenance training manual from CDC

http://www.google.com/url?sa=t&rct=...0oC4DA&usg=AFQjCNESVLzW-bfipzJ-IpmUD_eutyTIqw

I also found out google books has digitized computerworld magazines back to the mid 7o's at least, including the classified ads showing the huge activity in the used computer market back in the late 70's - early 80's. That's how I found out the model of the hawk was 9427H. A google for "computerworld cdc hawk" points you into some of the classifieds that google has kindly made available.

Hi All;
Thank You Doug.. Somewhere, I do have a copy of the Manual, But, now days, I do like the online version.. I can find it faster, once I have it.. And, Yes, that is exactly what I have as the number, now that rings a bell in the back of my mind, as the correct number.. I have never seen a course on the Hawk, the manual I have is only the maintance manual.. Interesting..
THANK YOU Marty
