Same here.

I remember when 50 of us shared a Prime 9955, and it had about 512K of
RAM total.

Timesharing systems are, IMHO, really good for learning.  For one thing,
there is a kind of community around those machines that doesn't exist
now.  It also taught us to be frugal with our shared resources.

Now there is little incentive for students to make their code better,
because they have so much brute force power, it is difficult for them to
see when they are being inefficient.

On a 20MHz 68020, or a minicomputer with 50 other users, you learn when
things are going wrong very quickly.

If you don't notice yourself, someone else will be sure and point it out
to you.

When I was doing IBM mainframe programming in the late 80s, our biggest
machine was a 4381, miles away in Richmond, VA.  Our drive volume had a
whopping 256MB of space, which just blew my mind.  I think it had about
32MB of memory, which again, blew my mind.
