I remember the days of the IBM/360 and Fortran IV and Algol and Cobol. The computer took up the whole floor of a building and had nothing like the speed and memory of today's notebook computer. I also remember knocking my stack of punched cards off my desk accidently and spending hours getting them back in order.

Most of these mainframes had all of 64kb to 256kb of memory; linear memory, not random access memmory. Yes, I wrote "k" and not "M". At my university we had a Cyber 3600 (or something like that) that predated IBM products. With itself and peripherals, it took up a 100x100 sq. ft floor in a refrigerated room. I cannot remember how many tape drives it had, but it was at least 30-40. The Cyber 3600 was state of the art for about a year!
And, yes, it was 80 column Hollerith cards in the long boxes the blank cards came in . I cannot count the number of times that fellow students fell or otherwise tossed the card boxes, and if the cards were not numbered, they had to essentially regenerate their code on the cards to sort them. It could take weeks!
I hated the Hollerith punch machines with a passion! I must have refused 2-5 cards for each one that would pass the compiler! ...and, as an undergraduate, I had to wait for days before I found out, from the printer output, that my code failed the compiler for errors. I would spend weeks trying to find the single coding error. I was a sophomore, and started to drink to relieve the pain.
$10-20 million for a computer system in 1966 than today can be had for under $50, used. To think we launched men to the moon with these computers! To think that the moon vehicles has miniaturized versions with very limited compiled code for these computers!
BTW, I converted some of my 1966-1980 (some professional code) Fortran IV code to Macintosh Basic in 1984 in my 128Kb original Macintosh with the single 128KB disk drive and no hard drive, and the progs worked just fine, except maybe 500x faster. I was overjoyed, even if the programs were dated and irrelevant!
Those were the days!
