Never knew that, that should be declared as international holiday for companies using mainframes!

Was the first 360 chip so small? Then why mainframes were so big?

[giskard reventlov]

small/big is irrelevant, what counts is the numbers of circuits on it
s/360 still had centrall memory of ferrite,
( 8KB would be the size of a shoe box )
and when one of the little rings stopped working the CE/FE would use
a tool like a knitting needle to thread the three/four wires used to address and read/write

That was a great, actually chip looked so compact for that time. I heard that mainframes were bigger than rooms so size mattered based on this reading I read somewhere.

Do you have more such picture, the description in them is interesting for me. Can you share more pics or can direct me to a link to further exploration.

Thanks again for sharing them.
