The CRAM units were on the 315's they also had.  There were rod memory cards, but I don't have a picture of one. I have many pictures of the data center (10)but haven't figured out how to post them on here. If you provide me with an email  (message me) I could sent them to you.

Hello,

the Link to the 605 nostalgia website seems to be dead.

This Link looks like the new address:
"http://www.geocities.ws/NCR605/"

Hello lapham,

thanks for your post.

>> I unstuck many CRAM units

Did they in the Chicago Data Center ran a 315 System parallel to the two Century 300, or - I can't really believe it - did they connect the CRAMs to the Century?

>>It was a big deal the day they installed a one meg memory unit

Yes, the 16k Rod Memory Modules for the Century were really big and heavy. I serviced some Century-100 with two modules installed. But (in Germany) on Century-200 with more than 32k we used a memory from Memorex? EMC? in a 19 inch cage - really small compared with the rod memory module. I don't really remember why, but timing problems could be the reason.

I searched intensively in the Net for a picture from the 16k Century rod module, but could'nt find any.

Greetings
Heiko

I wasn't a century FE but worked in the Chicago Data Center where they had 2 Century 300's. I mainly took care of the phone line problems as they were on-line to banks in 8 states. I was 605 trained so also did the 621.s and 721's. I unstuck many CRAM units and dabbled/helped on other units. It was a big deal the day they installed a one meg memory unit - the size of 2 refrigerators. Compare that today  to a cell phone - cell has probably 100 times the computing power.

Hi Wally,

nice to hear from you again!

I read your scanned press release - you are right.

In 1981 IBM presented the first PC. The available processors on the market were the 8086, the 6502, the Z80, Motorola 68000 and others.

On the other hand: the NCR-605 was available and heavy used in several machines. He was (at this time) evolved to a 2-Board-processor and was much more powerful than the 8086, the 6502, the Z80, Motorola 68000 and others.

And: The I-Operating Systems, Compilers and other Software were available for the 605. I'm really wondering: Why did they  write a complete new OS for the I-8100-Series?

I know: this is only a "rhetorical question" ....

Best wishes
Heiko

Hi Heiko,

I don't believe it's a 605-CPU. The I-8100 systems were build around 3 distinct microprocessors.
When more features were added to the system, more micros were added.
But I don't know, if they used Intels or Motorolas. Couldn't find any detail info in the I-net.
The OS was IDPS and the programming was done with Cobol-74.

Regards Wally.

Hello Miguel,

The processor, cage and boards looks for me as this is a 605 processor?

The owner wants to sale it?  Oh boy, good luck!

Hello Miguel,

I like that!

Are you able to make photos from the inside of the processor cabinet? Pictures from the Plugin-Boards and so on?

Greetings Heiko
