Review of IBM's Original Personal Computer

illiteratehack was one of several readers to point out that today is the 30th anniversary of the introduction of IBM's first popular PC, writing, "V3 managed to dig up the original review of IBM's Personal Computer Model 5150, the machine that popularized personal computing. There are some great comments; the article's author wasn't sure if IBM would sell the PC outside the US, and he mentions the inclusion of a 'very high quality 11.5-inch' display. The article also shows that while the PC may have changed a lot on the inside, the way it was reviewed hasn't changed much in 30 years." Other readers sent in reflections on 30 years of the PC by various tech icons and a speculative look at what the computing industry would have looked like without IBM.

      From Wikipedia:

      The Scroll Lock key was meant to lock all scrolling techniques, and is a remnant from the original IBM PC keyboard, though it is not used by most modern-day software. In the original design, Scroll Lock was intended to modify the behavior of the arrow keys. When the Scroll Lock mode was on, the arrow keys would scroll the contents of a text window instead of moving the cursor. In this usage, Scroll Lock is a toggling lock key like Num Lock or Caps Lock, which have a state that persists after the key is released.

      Not really. Depending on your usage, scroll lock is very useful at controlling a KVM. It can also be very useful if you deal with very large spreadsheets - even today you can hit scroll lock and then use the cursor keys to scroll through the document rather than use the scroll bars or mouse. Think of it as the "mousewheel" for the keyboard.

      It's a shame more apps don't use it - if you want to scroll using the keyboard, it's the best way.

      Though, you can have some fun if you hit scroll lock on someone's keyboard. Nothing really appears to happen, but if they use Excel or something...

    My first PC was built on an XT clone motherboard. Being an electronics tech and having built the S100 bus-based computer I'd been using for years, I decided to borrow a desoldering station from work over a weekend, and desoldered every chip on the motherboard so I could install sockets for all the chips against the eventual need for troubleshooting and repair. I never did have to replace a single chip on that board the entire time I used the thing.

      Agreed. I think back to 'the day', and while I had an Atari 400 and worked with both PETs and IBMs, the Apple ][+ was probably the watershed machine.

      Half a decade in the future, the Commodore 64 sold more units but that's because computers were popular by that point. People WANTED them! Lots of people had been buying computers (usually horrible things - the Vic-20 or the TI-99/4A) because they were exposed to the Apple at work or at school, and when the C64 came along it pretty much wiped the floor with the others (even though it had its own issues), but as far as I'm concerned, it was the Apple ][ series that created the revolution.

      The IBM was a business computer. Much better text, better computing power, pathetic sound, and nonexistent graphics. Oh, and an insane price tag--let's not forget that.

      It depends on where you were living I guess. I was in the UK at the time and my school got the first computer in the county in 1979 - a Commodore Pet 3008. That was the first machine I learned to program but the Commodore BASIC was feeble at best. A year later I bought a Sinclair ZX80 and then 81 and really got stuck into programming. The BASIC wasn't much better than Commodore though and I wanted more than the '81 could offer so was looking at the VIC20 (still that nasty BASIC) and then the 64 which was very crippled by the BASIC so most interaction with the machine had to be done through PEEK and POKE commands which resulted in really opaque code.

      Around the same time though, the BBC started their Computer Literacy Project and authorised Acorn Computers to rebrand their new Proton as the BBC Microcomputer System. The BBC Basic was astounding for the time with full structured programming languages and an inline assembler for performance. BBCs were very fast for the time with much better graphics than even the Commodore 64 but that wasn't the best thing, it was all the connectivity, expandability and the power of the thing. The BBC Micro was the machine that British schools took up in their droves and all kids going through school in the '80s would have used them. I got one myself and kept using it for the best part of a decade. I still have it and it still works. It launched me into a career programming and the language skills BBC Basic enabled have been relevant even today as a Java/C coder.

      The Commodore 64 certainly sold in great numbers, but it was more a consumer machine and didn't really turn out programmers like the BBC did. The 64 was more of an also ran in the UK market although it did keep going for a long time but it was basically seen as a games computer and little more.

      The funny thing is that today, with the standardisation on the Windows PC in schools, pupils are coming out of school less computer literate than they were in my day because they get taught to use applications (Office mostly) rather than programming. The ideals of the BBC Computer Literacy Project have pretty much been lost with the move to the Windows PC.

    As a die-hard Apple II user (still have my original //e and a spiffy Ethernet-equipped, Compact-Flash-card-as-a-hard-drive, maxed out IIGS), I've often pondered what might have been but for a few twists of computing fate.

    With just between 16KB to 256KB or RAM, a pair of 140KB floppy drives, an 80-column green-screen or RGB color display, 5 card slots, and an 8-bit CPU bus with a CPU running at far less than 10 MHz, the IBM 5150 isn't that different than a contemporary Apple //e (typically with 128KB of RAM, a pair of 140KB floppies, a green screen or RGB display, 7 card slots, and a more efficient 1MHz CPU), and it wasn't obviously superior at the time. Both had similar expansion abilities (serial, parallel, game, modems, primitive hard drives in time), yet industry chose the PC to build upon because it was legally simpler.

    What might have been if Apple allowed industry to clone and build upon the Apple II architecture, I wonder? Would we have had Compaq building luggable Apple II's with 16-bit CPUs and expanded memory early on? Might we have eventually had Apple IIs with 16-bit ISA slots, then VLB slots, then PCI slots, then AGP slots, and now PCI Express? Might we today have thoroughly modern computers with slick Windows-like GUIs, but if you did a Control-Reset or booted off of a USB-connected legacy Disk ][ you could still enter an AppleSoft BASIC program equivalent to booting off of an MSDOS boot floppy and doing a "dir?" Might our keyboards still have Open-Apple and Solid-Apple keys instead of Alt and Windows?

    If you can find an old computer magazine from the late 70s (BYTE, Dr Dobbs, Creative Computing, etc) you'll see ads for all kinds of different systems. It was like the early days of the automobile industry when there were many manufacturers that are all but forgotten now. Too many for it to last; there had to be what marketing people call a 'shakeout'. When IBM announced the PC, it legitimized these home computers in the minds of a lot of people who liked the idea of having a computer in their home with the 3 letters IBM on it.

    But they were expensive and soon people were buying the cheaper clones. As I understand it, IBM was still mostly interested in their Mainframe business. They left the PC's architecture 'open', which allowed the cheap clones to be made. This was a decision that had important consequences I think. If IBM had suppressed the clones, what would have happened? Perhaps Apple would have become top dog in the home PC market, or perhaps some other company. Would there have ever been any 'open' architecture at all? The openness was spoiled by Microsoft cutting deals with the hardware manufacturers of those clones so that no other software had much of a chance. My feelings about Microsoft should be clear from my sig.

    My big disappointment was that IBM chose to use the Intel 8086 chip. The Zilog Z8000 and Motorola 68000 were much more advanced, and I thought it was a pity that they became niche architectures by comparison. I realize IBM wasn't interested in creating something 'insanely great'. Mediocrity, or even downright inferiority prevailed. There were sound business reasons for IBM's decision at the time, but that doesn't mean I have to like the result.

When I got Doom networked on 4 computers in our house (damn ipx hack setup), it was revolutionary for me and my friends - it was just massive intense multiplayer fun, when AI opponents were truly laughable, and games weren't about stories.
