Digital Retro

I spent several hours this week poring through Gordon Laing's beautiful book Digital Retro , and it's one I'm sure to return to at odd moments, the same way I like to flip through old copies of The Whole Earth Catalog. Digital Retro represents years of research into a 14-year stretch of personal computing history, distilling that effort into a work that is graphically appealing, but also an informative, informal historical look at the machines it celebrates (all 40 of them). Depending in part on what year you were born (and at what age computers entered the picture) you may recognize most of these machines, or only a few -- it's an equally fun read either way. Read on for the rest of my review. Digital Retro: The Evolution and Design of the Personal Computer author Gordon Laing pages 192 publisher Sybex rating 9 reviewer timothy ISBN 078214330X summary Eye-candy mixed with a good dose of history, perfect for the library of a modern techno fetishist.

Digital Retro is about personal-use (though not necessarily home-use) machines: there are no PDP11's or mainframes represented, nor devices like the DECWriter, which gave computer access to individuals but required a mainframe or minicomputer in the background. The book covers hardware that was sold at retail (barring the Altair and a few other mail-order-only kit machines), at prices householders could afford for their hobby use, including gaming, or that businesses could afford for their executives and other knowledge workers. All the same, the prices are sure to make you calculate every so often things like how many BogoMIPS could be had today for the $3,250 that a 613KHz HP-85 cost in 1980 -- and those are 1980 dollars. Early adoption has its risks as well as its rewards.

From iconic to obscure

Too many computer makers (and even more computers) came and went in the decade-plus spanned by this book for it to cover all of them; Laing's list of chosen machines is representative rather than comprehensive. More than 30 of the machines came from the The Museum of Computing in Swindon, and despite their age most look like they just popped out of their delivery boxes.

Digital Retro's central section starts out with a MITS Altair, the machine generally considered the first computer practical for a hobbyist to buy. (And the buyer had to be a dedicated hobbyist; the Altair was sold in kit form for home-assembly, and its display was a series of winking lights, its input facilities a row of toggle switches.) "Practical" in the case of the Altair meant affordable and accessible -- there wasn't much of a practical nature for the solder-weary user to actually do with an Altair once it was assembled; the chicken and the egg of availability and usefulness were still fighting it out at this point in computer history. The Altair also has another interesting spot in personal computer history: it provided the first platform for an operating system from Bill Gates and Paul Allen.

(There's an Apple I in homemade wooden raiment snuck into the book's introduction -- an Apple I proved too difficult to find for a full writeup and photoshoot, however, and no Apple II clones made the cut.)

From the Altair to the NeXT cube which caps off the Digital Retro's collection, the 38 machines (and in some cases machine families, such as the MSX computers mentioned below) are presented in order of appearance. The book presents too many interesting machines to give each a proper summary, but here are a few to whet your appetite:

  • The Sharp MZ-80K (December, 1978) -- with its 10" screen and built-in drive (tape drive, though -- the 3.5" diskette wasn't invented yet), the MZ-80K seems ahead of its time; the choice of a Zilog Z80 processor didn't do much for its longevity as a business system, though; Z80 systems were soon eclipsed by other choices.
  • The GCE/MB Vectrex (June, 1982) -- the only video game system I really wanted as a kid, and one of the seeming few I've never encountered used in thrift stores. Bright vector graphics, built-in screen and a quality joystick gave it the same kind of appeal that the arcade-console versions of Asteroids and Battlezone had for me.
  • The Jupiter ACE (September, 1982) -- an impossibly simply looking machine, a terraced slab of white plastic with a minimalist typewriter layout (just 40 grey keys). The ACE was aimed at programmer-hobbyists, though, like the similar-looking Sinclair ZX-80, but the ACE ran a version of FORTH and had raised keys rather than the Sinclair's flat membrane.
  • The Sinclair QL (January, 1984) -- one of which, Laing notes, was Linus Torvalds' machine (between a VIC-20 and the 386 with which Torvalds started a quaint Unix-like operating system).

Game consoles are also well represented; six dedicated game machines, starting with the Atari VCS (1977) are included; a whole book could be devoted to consoles, but the ones chosen for Digital Retro (besides Atari and the Vectrex mentioned above, the others come from Colleco, Mattel, Nintendo, Sega) are an eclectic bunch, and a good use of space.

Because Laing is based in the UK, the book features quite a few machines that most Americans have probably never encountered in person, like the Acorn Atom, the Dragon 32 (a Welsh-made near-clone of the Tandy TRS-80) and the Grundy NewBrain. If this book had been an American production, many of these UK-made machines might have gone overlooked.

No incentive to work together

In the wilder days of the personal computer's adolescence, the quest for compatibility and standardization among machines was anything but a top priority -- and when it was a factor at all, it was usually about software compatibility between sibling computers (like the TI 99/4 and its 99/4A successor) or at most within a single model line.

As the book's back cover points out, "Compatibility? Forget it! Each of these computers was its own machine and had no intention of talking to anything else." An overstatement, but not much of one.

Laing covers an intriguing exception to this one-off philosophy, a multi-manufacturer line of machines that appeared in 1983 (starting a 5-year run), sharing a Zilog processor and adherence to an early Microsoft attempt at standardization called MSX. Mostly-compatible machines were launched by JVC, Hitachi, Sony (a name that didn't pop up in the American computer market for quite a few more years) and 18 other Japanese manufacturers as well as SpectraVideo, the only non-Japanese maker. Each manufacturer tweaked their entries in the line to distinguish themselves, adding features like (in Pioneer's case) control of laser-disc players. The differences soon rendered the attempt at standardization moot, and the MSX standard fell from grace. And if you're wondering what MSX stands for, you'll have to choose from the three possibilities listed: I prefer "Matsushita Sony X, where X could stand for any other company."

Get a good look

The photographs dominate; they give external views of each machine from several angles, over two two-page spreads apiece. (The pictures are well-chosen, but not exhaustive: there are no shots from the underside, and in only a few cases are internals exposed. Don't expect to replicate the innards of an Altair from the photographs.) You can make out what sort of ports each device provided, see what kind of display it used in most cases, and look at the included input peripherals. (Many of these machines, though, were hooked to televisions, and only the main unit and its input devices are pictured.)

Speaking of peripherals, one of the nice things about a photo book like this is for the mugshots it provides of unique physical arrangements tried by computer manufacturers: the integrated tape drive of the black-clad Amstrad CPC-464 (which sits to the right of the keyboard) makes it one of the most interesting to me; it sure is a lot neater arrangement than the cassette drive linked messily to the family C64 in the early '80s.

Besides the photographs, though, the spreads devoted to each computer provide a compact history of the machine, list its country of origin, and give a rundown of the most important specs (processor type and available I/O ports).

Practical Upshot

Digital Retro is a coffee-table book which happens to have quite a bit of interesting history, not a deep historical text. For each machine displayed, though, a chunk of text titled "What happened next" gives an idea of what developments each one led to (or prevented); some of these are only a paragraph or two, others are mini-essays in themselves. If you crave more technical and historical details, Laing's book makes an excellent companion volume to narrative-centric books which cover the same period of computer history though, like Fire in the Valley and Steven Levy's Hackers. It's a perfect way to appreciate the aesthetic appeal (and exuberant variety) of personal computers from the mid '70s to the late '80s.

    Some of these old systems never loose their appeal... A few years back, about 4 if I recall, My boss asked me to find him a computer. He is a pioneering engineer type, never went to college, designs aircraft sensors with pen & paper... And wanted a single-line display handheld computer that took some BASIC variant for a programming language. A high tech toy from the early 1980's.

    I found one on Ebay for like 5 bucks - He uses it almost daily. I guess if it works, you don't need to add features and soak up RAM.

      Wasn't one of these, was it? Or one of these? Those were Psion's early handheld computers.

      Rumour has it (from a chap I used to work with at Psion) that they were in the process of writing a database app for the ZX-Spectrum, when someone said something like "hey, wouldn't it be cool if you could get one of these in your pocket?" and thus the handheld computing industry was born.

    that issue is probably the one thing that drove people to the ibm/msdos standard more than anything else. I remember cartoons around 1985 of a salesman showing a real kickass machine with a great price, sound, graphics, etc., to a customer and all the customer could ask was, "But is it PC compatible?".

  5. Those were the days... by Seventh+Magpie · · Score: 4, Insightful

    You know everyone in a while it is nice to reminisce about the good old days. Back when it was unpopular to use computers. You knew if you met someone on a bbs or at a computer club meeting, he or she (sometimes she, but rarely) would be just as geeky as you. You were into computers not because it was cool, or because your job required you to, or to make money, or to pick up girls, but because you loved exploring this new frontier. I remember when I was about 8 or 9 playing outside when my dad came walking home from the bus stop after work with a Commodore Vic-20 on his shoulder. My life changed from that day on. We used to sit down and program BASIC taking turns reading and typing code from Compute's Gazette. Spending hours trying to debug after because the programs never worked on first try! Boy life was grand back then. But then again, I am sure if I read that book, it would make me sad in a way as well. I kind of miss the good old days and one can never go back.

    Man, I miss 8-bit computing. Back in the good old days, you just peeked and poked (or LDA'd and STA'd) wherever the heck you wanted. Ask the system for resources? Bah! If I practiced poor memory management and ran out or overwrote something, cool things would happen. Text would change shapes or colors. The screen might change color in the middle. The joystick would work backwards and the tape drive would have a life of its own.

    Back in those days, when I knew the entire 6510 assembler command set and the entire C64 kernel jump table by heart, I could do ANYTHING. I could even debug programs after assembly and correct for assembler errors. 032 212 255? No way!! That's 032 21*0* 255, or JSR $FFD2, the "print character to screen" routine. Let's just shave a bit off one of those bytes and we're good to go...

    Now there are so many languages and so many implementations of each... And so much hardware to support and abstraction layers... It's not that it's harder... it's just not as much fun anymore... Maybe I'll get a C64 emulator and type in the development kit from Compute!'s Gazette again!

    Back when you could walk into any mall and locate the arcade from the sound of the fleas falling in the centepede game, which was always cranked up to max volume. Back when it was fun to key in programs from the back of some magazine. Back when hacking out routines in assembly was common. Back when this was a new frontier and people who could make computers do things were like magical wizards. Oh, and here's one for you... back when you could get a rootbeer float at the local Woolworths in between quarters at the local arcade! Heh.

    Now-days it's all commonplace. Any bozo can hop down to the local Comp-U-Comp, drop a grand and be on the Internet inflicting himself on us in a matter of minutes. The frontier's been pushed out considerably, and we've traded in our hand-coded assembly language routines for pre-made GUI libraries. For every wizard who takes pride in his work there are a thousand code monkeys who got into this business for the money and a hundred managers who want that wizard to work faster not smarter. It's called progress...

    I reviewed (http://dpnow.com/1299.html) this book on my site a couple of days ago and submitted a summary here but had no idea Timothy was on the case already. Gordon Laing, the author, and I meet up quite frequently and I was able to gain some fascinating insights into his research. One thing that rather depressed me was that some of the icons he spoke to, like Chuck Peddle and Sir Clive Sinclair are now, apparently, getting on a bit and are rather forgetful of the times they made into the golden age of personal computing. The book is, as Timothy says, a marvelous piece of work. It's meticulously researched and extremely well written. Timothy mentions the pictures - it's rather like having a book of old brochures, but much better, though I observed in my review that there are no pictures or direct quotes from the personalities of the period (1974-1988). I've been using and writing about micros since the late 70s and I still learned a whole bunch of interesting and fascinating anecdotes. One of the nice touches Gordon lends to the end of the book is the reminder that while the hardware might eventually die, the souls of some of these computers live on in the form of software emulators that run on contemporary hardware. Gordon deserves all the success this book appears to be enjoying. Anyway, I'm off to find my BBC Micro emulator for a spot of Elite - Right on Commander! Ian

  10. Sinclair Scientific calculator of 197x by dankelley · · Score: 4, Interesting
    I know this is a bit off-topic, but we all started with calculators, right?

    The Sinclair Scientific http://www.vintagecalculators.com/html/sinclair___ the_pocket_calculat.htmlhere was my first calculator. It came as a kit, and it had a small-stack RPN scheme that required remembering numbers or writing down intermediate parts of calculations. I think it only had sine, so you had to get cosine by a root(1-sin**2). It had so little memory that values of e, ln(10), etc., were written on the case! (Hm, I wonder if this is why I remember ln(10) to this day, whereas my students have no clue about the value...)

    I loved this little calculator, partly because it was so light compared to the fancy, expensive boxes the other kids had, but mainly because my Dad had given it to me. My heart ached when I looked up a picture of the little calculator, after reading this thread. This, I think, is why reminiscing about old technology is useful: it dredges up memories of simpler days in all our lives, when an infinity stretched before us on a path so bright and smooth.
