History of Computer Hardware

[mt-qcqh]

I remember working on my first mini-computer, the original DG Nova. It had a whooping 4k of core memory and in order to load anything you had to toggle in a 12 instruction Bootloader with the front panel switches. Shortly after the Nova 1200 included a "program load" switch that did it for you! Now I program the ESP's, millions of times more powerful. I loved it all. Thanks for the nostalgic trip along History lane.

When I studied mechanical engineering (1966 - 1969) the only tool for calculations was the slide rule. In 1969 I joined an insurance company as a trainee programmer. The company had an IBM /360-50 as well as an old IBM 1401 and a dedicated IBM /360-40 system for the life insurance part.
In 1972 I moved to a department retail company. They still used an old Univac UCT system as well as two General Electric 400 system. A small IBM /360-20 was used to drive an IBM 1287 reader which could read handwritten digits as well as OCR-A type print. A Honeywell Bull system 6040 (with extended instruction set) was on order.
For 10 years I have been a system programmer and then leader of the system programming and system supervision team for the Honeywell Bull and IBM systems. After that I have been working for a consulting company specializing on performance analysis and system modelling. My last job was with Honeywell Bull / Bull /Steria mainly in document management and system integration. It was an interesting time and completely different from today's environments.

this is the most complete video with compact information i could find in the platform, thank you so much proffessor!

Mr. McElroy, I learned some BASIC programming on an IBM 360, 1983. Same year, a Christmas gift was a TI 99 4A! Set up to a color tv and cassette(TI) brand. Software on cartridges.

I cant believe this does not have more views. Great info (even if you are wrong about Ada Lovelace) thanks for the great vid!

thank you so much for this amazing video, this has helped me so much with my presentation on computer hardware!

Bonjour, c'est une chance pour nous qui somme né dans les années 60. On connait l'évolution et l'histoire de l'informatique. Ainsi que les magazines de l'époque dans les années 90.

I grew up in Mountain View. Steve Jobs lived around the corner. Great years to grow up.

In the olden day we used chisels and stone tablets to write the news... it was hard work... and we used messengers that used horses to send a message to someone... that took 4 weeks one way...

If we wanted to watch... uhm... pictures of adults doing adult things we went into caves and painted the cave walls... :-)

yeah. well. while charles babbage's machine may have seperate program and data ram -most- modern computers do not. whereas for example the 8086 line does have a seperate i/o space which can only be addressed with special instructions. and some setups do have a fully seperate address bus for video (not even just one pin, no the whole thing), but usually it's not seperated in data/code. pic mcu's being one of the few common exceptions that actually have -that-.

when you are talking about the war, you stay on topic: this compinent was made for this purpose in the war.

when you are talking about social/polotical/legal events, you drop the purposes for which the components were made.
