I always wondered what if time hardware development stopped in 1969: how far we couuld go with such machines with new fresh software? :)
A lot of our software really depends on things like fast disks and significant memory. I think we might have ended up with the development of memory-constrained algorithms that don’t exist now, and computing would be very much a batch-mode endeavor rather than the interactive process we have now.

Add ten more years, and the IBM 801 could have been a CPU architecture good enough to scale all the way to the present day without emulation, unlike the 360.

#14It was used by reservation; that is, someone requested a time slot and got access to the computer for that time (paying the required fee, of course). IIRC, it even ran overnight.
I saw the system while I was a pre-teen, in 1982. At the time, it was still in operation even after more capable systems were installed and microcomputers were making their inroads. At that time its usage was reduced, but CNC folks told me it still was used by some civil engineers who did structural calculations with it.

#16The DMS operating system on the 1130 had a 5-character filename limit. Chuck Moore wanted to name his language FOURTH, to signal a fourth-generation language. The filename limit truncated the name to FORTH. A disk system constraint from 1968 is why the language is called Forth.

#17It's amazing how many different, incompatible computer systems IBM had back then.

In 1969 we had Lisp, and the PDP-10. Interactive computing was very doable even then. I'm sure Stallman would have love for ITS on the 10 to have remained the default.

It was a very common thing until the world settled into PC vs Mac for the most purposes, until tablets and phones came to be.
