"Back in the day" I worked on the Software QA team in Wichita, Kansas for the IMOS, IMOS III, and IMOS V operating systems. All of them ran on the 82xx/9020 minicomputers. For retail systems, the same hardware also supported the TCOS OS, core of the STORES retail system, which had a "full-featured" back-end operating system.

As if that weren't enough, there was also the ICS retail-store scanning system, which was highly optimized to serve bar-code scanning retail terminals. ICS was capable of handling 15 scanners that scanned an aggregate of over 50,000 items per hour.

The NCR Corporation and Dayton History joined in an innovative partnership committed to preserving the NCR Archive.
This link provides lots of old photos from NCR and Dayton.

I do not have a photo of DC office but just wanted to let you know that the current issue of NCR_REA is now available on line to members. There is a aerial photo of the Dayton complex  that is new to me. I would guess about 1960 or 61.

I agree that the modules are from a compu tronic , The photo just posted is exactly as I remembered seeing them in Grand Rapids Mi when I was an apprentice.  Marv Kloote was the first CE trained on this machine.

Hi Marv, you are right. I found an old picture of the inside of a 441 at ITEC Giessen.
I was probably thinking of a 395 or 400. I found it in this PDF.

At least the module 3 from above seems to be from a 441.

I remember things like 12AS7s…6SN7s…thyratrons…massive cooling fans…165-volt anode voltages...anodes, cathodes and grids. I don't remember any transistors in there. But I could be wrong.

Hi Marv,
I'm not the only one, who thinks the Computronic was transistorized.

Hi Wally,
I think you might have the Comp confused with some other system. Your timeframe is correct but the Comp was anything but leading-edge. It used old technology, nothing like the showcase EDP systems of the day.

The first NCR computer (315-100) I taught in the UK had a 10k memory (slabs) A slab was 12 bits which could consist of two alpha numeric characters or three numeric characters. I later taught the Century 100 which had 16k of memory (bytes). 
The laptop on which I am typing this message has 8Gb of things have progressed!!!!!!

Hi Marv,
if I remember right, the Computronic was transistorized. But I'm not 100% sure.
It came on the market in 1959 and I think by that time transistors were used.
It is the same time, the NCR 304 was introduced and it was the industry's first
all-transistorized, or solid-state computer for general business in the market.
Regards Wally.
