It might break the rules since it only goes back to 1999, but here's
Moore's law for integer speed, floating point speed, number of processors,
memory sizes and disk sizes for the machines connected to SETI at home. Plots
are averages and medians, unfiltered for errors. At least one of the
parameters (total credited ops) is no longer used. expavg credit
includes GPU work even though it's not included in the processor speed
numbers. If someone wants a distillation of the data for comparing to
earlier machines, let me know.

I?m not trying to date myself but have things truly sped up? In 1970?s
Toronto I had a classic computer, sorry can?t recall what it was,
connected
to a 300 baud modem; by early 80?s had ?zoomed?
to 9600 baud. Oh, my! [ A
typical file size to download was probably 1 MB. ] Speed indeed! Yet now,
here in rural Ontario, Canada, I?m at 5MB/s. Yikes! (Friends in Toronto
are
at 50MB/s.) We can do the math but content,
particularly multimedia, has
swollen in size.[ 1 GB is not unheard of. ] Were classic computing days
that much slower? Happy computing. Murray -:)
I remember downloading the GCC release kit over a 56k dialup line, in
2000. Took a while.
The ARPAnet in its early days had "high speed backbone" links which were
56k bps. Terminal links presumably 110 bps, that being the speed of ASCII
teletypes. And back in the late 1970s you could still find even slower
links in some places, such as 6 bit links connecting teletype machines for
newspaper "wire service" feeds.
It would be fun to do a "generalized Moore's Law" chart, showing not just
transistor count growth (Moore's subject) but also the many other scaling
changes of computing: disk capacity, recording density, disk IOPS, disk
bandwidth, ditto those for tape, CPU MIPS, memory size, memory bandwidth,
network bandwidth...
All these have grown dramatically, but very clearly not in the same
proportion, for some of these the changes are smooth while others are
jumps, and the rate of change sometimes varies dramatically over the
decades.
