Title: NCR I-9020 'any' information wanted
Post by: hunt3r on May 18, 2010, 02:02:07 pm
I just aquired a NCR I-9020 minicomputer (according to Computerwoche archiv introduced in Germany in 1981). I'm not able to find any information on this system online (not even in this archiv or forum) - so, all kind of information on this system is welcome.

The I-9020 ran on the same basic operating system as the 8200 series which was IMOS III & V.  IMOS II worked on the 8200 serieis but I mostly saw IMOS III on I-9020s which had 16 bit processors and started with 128K of memory, upgradeable to 256k, and in 1984 there was a I-9020 at Pueblo (CO) city hall that ran IMOS V (I understand IV didn't work too well), had 512k and could support up to 24 dumb terminals.
The NCR museum at dayton OH has information on IMOS III, but it is not digital, so you would have to go there yourself and go through the archives to find the information you need.
At a later date I may be able to scan some os information for you as well, but I don't know how helpful that will be.  Dayton probably has about everything there is.

One more thing re; I9020s.  You will find much more on the net about the 8200 series and much of it will apply to the I-9020, especially the 8250.
