Computers - my how they've grown

From my first computer, a C64, up through when individual core clock speed topped out in the mid oughts or so, each computer I bought new for home use had almost exactly 8x the clock speed of the last one. MOS 6510, Motorola 68000, an early Pentium, etc. :slight_smile:

My first computer was a VIC-20 with 5 KiB RAM. My current system has 64 GB, so >10M times as much. The only storage I had initially was a Commodore Datasette (a tape drive), which had 100 KiB of capacity (my 4 TB of SSDs have 40M times the capacity, and my 64 TB storage server has 640M times) and could load at a whopping 300 bits/second (my SSDs read at ~4 GB/s, which is >10M times faster).

Basically every component in my system is >10M times better than it was.

I find it remarkable that we now carry in our pockets more powerful computers than the ones that put human beings on the moon, and all this has happened in my lifetime (more or less, I was born the month after the Apollo landing).

I started college in September 1984 and brought a Commodore 64 with me to school, while my roommate brought an Atari 800. He had a 1200 baud modem, while mine was only 300 baud, which meant that I could read faster than the text scrolled up the screen (of the 13" TV I used as a computer monitor). And for a printer, the roommate used a daisy-wheel typewriter that had some sort of interface to his computer. It made a horrible racket when printing.

The computer I learned to program on in high school was an LGP-21 with 4 k of 32 bit memory on a disk - no RAM, except perhaps the Accumulator register and a few other. Only output devices were a Flexiwriter and paper tape. No assembler, the first one I used I wrote myself. No ASCII, they had their own character code.

In college I used Multics, a 360, and took an assembly language class on the PDP-1 where Spacewar was developed. We got to drive that very same CRT. Ed Fredkin boldly predicted that some day memory would be a penny a bit.

In grad school we used a PDP 11/20 with 16 K of memory which we managed to upgrade ourselves. It used a washing machine sized hard disk drive. Each of us had a platter for ourselves we’d insert before we started using it.

My first computer was a Commodore VIC-20, with all of 3.5K RAM (advertised as 5K, but there was some overhead when you turned it on.) Datasette cassette drive. Then I moved on to a C-128 some time c. 1987. The I went off to college in 1993, and just used lab computers. The next computer I owned was in 2004, some cheapie PC, then I got a MacBook Pro a couple years later and never looked back.

My first computer was similar, a C-64 with datasette. A system so unbelievably outmatched by the smallest “smart” device I have in my house now that it’s ridiculous. Nonetheless, I never had more fun with a computer like then (yeah, mostly because of the games).

Also how I learned to program. Sure, most of my programs at age 6 were along the lines of:
10 PRINT “BUTTS”
20 GOTO 10

…but there’s something to be said for having a programming environment available seconds after turning the machine on, without having to install or run any other tool.

Ah, I was a lot more sophisticated when I got my C-64 at age 16 and added a semicolon to the first line to print butts all over. :wink:

Did you also turn your calculator upside down after punching in 7734 or 58008?

the first computer I ever used was the old apple iies they would cart around the schools for a once or twice a year workshop thing so we could use “turtle” thing then dad lent me a ti/4 a in the 3rd grade I used a VIC 20 and then owned one later then I owned a c64

and then a 486 Pacbell pos I had to upgrade to make useful … then a p120 … and I’ve used my aunts computers ever since

I forgot about that one. However, I do remember the shortcut for PRINT:
10 ? “BUTTS”

Of course! Also 55378008.

You can even cut it down to (on a C64, at least):

0 ? “BUTTS”:GOTO
RUN

If you don’t put a line number after GOTO, it interprets it as a GOTO 0. Little trick to make your code even more inscrutible.

My first computer was an Apple ][+ (yeah, they used brackets) with 48k memory, about 1980. The printer was extra. A monitor was extra, so I just used an old 12" black & white TV. Code was stored on a cassette tape. The computer cost about $2000. I don’t remember what the printer cost.

I’m writing this on my 21" iMac with 1 terabyte of memory. It has a Bluetooth keyboard and mouse, no external storage (no need for it), a built-in monitor that’s been commonplace for so long they don’t even mention it in the ads. I think it cost around $1200, maybe $1400. My laser printer/scanner was around $250.

When I was a graphic artist transitioning from analog to computer graphics, the first Mac computers I worked on came standard with 80MB hard drives. And graphics work is extremely memory-intensive, even back then. But somehow 80MB was enough. Of course we had a lot of external storage and file transfer methods, Backup with digital tapes. Anyone remember Zip drives? They had a generous storage capacity but, I seem to remember, a notorious failure rate.

LGR looks at Zip Drives.

You used to be able to get a button that said,

Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.

Commodore 64s were THE gaming computer for a stretch in the mid-late 1980s. PCs kind of stunk in terms of sound and graphics at the time, but the c64 had fantastic sound, and better graphics until about the early-mid 90s. So most “big” games of the era were c64 games.

The term’s raster display. Dot matrix is a printer term.

Yeah… they were basically overgrown floppies. IIRC they were 100 megabytes, and hooked up via a serial port. I used to use one to shift stuff home like game updates or other large files that I had downloaded through my employer’s ISDN connection (boy isn’t that a blast from the past?) because it was considerably faster than my 33.6 modem.

It worked fairly well, but you’re right- the individual disks were prone to getting screwed up, so they were terrible for longer-term storage. But they worked fine for just moving stuff from place to place.

I’m old enough to remember when IBM’s most popular mainframe maxed out at 16,000 six-bit characters of RAM and 5 hard disks, each one with 2,000,000 (and each the size of a washing machine). I’m not sure just how much it cost, but it was on the order of $10,000—per month!

I can remember when a machine with only a fraction of the power of an Apple Watch would have taken up a warehouse and required water cooling.
