Personal computing. Personal. Computing. We take both aspects so completely for granted these days, it's almost impossible to think of a time when computing wasn't personal - or when there was no electronic or mechanical computing. To get from there to here, we've gone from a time when 'computers' were people able to do perform …
The Apple machines really weren't that important or successful until the Mac came out.
Try looking at the other home computers of the era, especially those from Commodore. Don't believe the Apple revisionists, even Apple lied about who sold a million machines first (it was Commodore, not Apple).
The VIC-20 was an early 80s machine though. Maybe we'll see it tomorrow?
> The Apple machines really weren't that important or successful
Maybe, but I used one in the office back in the early 80s. Great little machine, 48kb memory, twin floppies and the killer app, Visicalc.
When the company acquired its first IBM PC it seemed inferior in every sense. "It'll never catch on", thought I. Thus starting my ability to be 100% wrong about new technology.
DOS or CCPM? - no question, Concurrent CPM was superior in every way!
Future PC with CCPM or IBM PC with PC-DOS? - no brainer, I can multitask on my Future pc and store data on my 800kb floppies rather than 1 thing at a time with 360kb storage.
Word Perfect of MS Word? - easy. MS Word is so clunky it's all but unusable
Apple Lisa and a mouse? No-one needs a mouse
If only I had bet against myself
For me the Apple II was a distinct improvement on my 1976 Motorola 6800 evaluation kit. Visicalc was useful for expenses. However the Apple's most powerful feature was being able to add home-brewed cards to interface to other electronic kit. At one point it was emulating an ICL 2900 mainframe, or its various terminals, to enable bug resolution on comms software. It also acted as a peripheral to a MOD 1 bus to suck software diagnostic traces out in realtime.
No Apple has ever had a similar "buy me" lure since that Apple II. The Apple Lisa was never considered - it was just an expensive appliance. So the upgrade path went to IBM PC clones with their ISA bus for home-brew cards.
Here's hoping you're confidently expecting Windows 8 to be a runaway success then.
Why am I not surprised? After reading a well-researched peice spanning 170 years' of innovation and the first comment is someone bashing Apple.
Say something intelligent and relevant or fuck off
"Say something intelligent and relevant or fuck off"
Well that rules out Microsoft.
Well. the Apple I does not deserve to be mentioned here as the "first" one, or at all. Radio Shack perhaps. Apple II is Ok in this list, not least because of VisiCalc. Then there are of course plenty of other computers that could have been mentioned but I suppose the list would have been too long then. My first computer was an Elliott 803 in 1968. Algol, punch tape and a plotter. Far more capable than the Apple II except that Apple had floppy drives.
They were made by Shuhart and very unreliable bastards.
Historical revisionism is bound to upset those of us that actually lived through this stuff.
In my mind, the Apple 2 line will always be associated with Apple's tendencies to gouge it's fans. Apple was gouging people for 8-bit machines well into the 68K era to the point where you could get an Amiga or Atari ST for less than an Apple 2.
That sort of thing tends to put a damper on the spread of technology.
Wow where were you? I had an Apple IIe way before Amiga's and ST's came out. There were several years of no crossover in dates between them as i recall. No chance of buying them at the same time....
It was to be the last time i touched an Apple product but it was awesome. Loved that little white plug for analog games controllers for robotic experiments etc.
My UK Apple II had 48KB of memory and a 100KB floppy drive. At GBP1750 it was an expensive buy - but it was bought for function not form. With no Apple brand established in the UK it was a straight fight between the few PCs of that spec on the UK market. I suspect that Apple was the cheapest at that time for that spec.
To put the cost into perspective - in 1980 another new technology, a JVC "portable" home video and camera cost GBP1350. In the late 1980s an Elonex IBM clone base unit with 640KB of memory, floppy, and a 20MB hard disk cost GBP2000.
0. The Antikythera mechanism?
Indeed, or even perhaps the abacus?
There was a programme on Radio 4 this week about Japanese arithmetic competitions, and the culture around maths in general (favourite sums displayed outside Shinto temples, for example). Quite eye-opening, and staggering the feats these people can do in their heads.
On the subject of BBC output, there was an hour long programme about Tutte and Flowers on BBC 4 (TV) on Sunday evening. Both are still available on iPlayer. Flowers, who built Colossus, attended an 'Introduction to IT' course when he was 87 and received a certificate to say he could perform simple tasks on a PC.
Oh heck, OT, whilst I'm plugging radio and TV shows, this programme is about how Rupert Murdoch set up a company to reverse engineer his pay-TV competitor's systems, making piracy rife: http://www.abc.net.au/radionational/programs/latenightlive/pirating-pay-tv/4339420
How about that mainstay of engineers over the years, the slide rule?
Not only that
There's talk of pioneers like Babbage and Flowers but no mention of Ada Lovelace or Alan Turing? WTF El Reg?
Re: Not only that
Um, possibly because whilst Babbage and Flowers designed and actually built computing devices, neither Lovelace or Turing did. This article is mostly about the hardware, not the theory behind it.
Purportedly invented by Archimedes recent research has shown. So it must be good.
I'd be the first to bash Apple at any opportunity, but in this case the Apple ][ deserves its place here. It was the first micro-computer to allow third-party plug-in cards, and it prospered for that reason. Maybe without the Apple ][, the IBM engineers would never have had the idea.
But where is the Manchester Baby? It was the first computer to store the program in rewritable memory. So no rewiring or punching film to reprogram it.
And I think you will find the Ferranti Mark One may give LEO a run for its money.
Oh, no it wasn't.
The IMSAI 8080 (http://en.wikipedia.org/wiki/IMS_Associates,_Inc.) and MITS Altair 8008 (http://en.wikipedia.org/wiki/Altair_8800) both allowed third-party plug-in cards, and were launched in 1975.
That predates the Apple ][ by two years.
Whilst I will happily defend the Apple II's place in this article, and in the history of personal computing generally, the first micro-computer to allow third party plug-in cards was the Altair, or anything that came before - pretty much all micros were based on some derivative of the S-100 bus precisely to allow expansion with plug-in cards, and there was a healthy third party market selling them way before the Apple II.
"But where is the Manchester Baby?"
Agree wholeheartedly - was taught Physics by someone who had worked on it as a student.
Any reference to Leo always reminds me of the story my father-in-law (95 and still going strong) tells. Lyons offered the use of Leo to the Inland Revenue to calculate the tax tables after a budget change. One year he was selected to go to Lyons, taking with him the highly confidential envelope that contained details of the tax changes to be announced in the budget. The rule was that the changes were secret until the budget announcements were made and the chancellor had sat down. Which meant waiting for the phone call to say that the chancellor had sat down. The envelope could be opened and the details given to the Lyons' techies. He opened the envelope, took out the paper that was inside and read it - "No Change".
Let's not forget the Whirlwind:
Completed in 1951, it was the first real-time (not batch) computer, and the first to use video displays for output. The Whirlwind project also later gave us core memory, and light guns as input devices, which I would enjoy many years later playing Duck Hunt on the NES. A guy named Ken Olsen who apparently went on to do some other stuff with computers also worked on Whirlwind. : )
(Full disclosure: my uncle worked on Whirlwind)
Also worthy of mention
is the IMSAI 8080. I had one, which I initially programmed in binary using paddle switches. Later I added keyboard, monitor and support for audio tape storage, then finally added 8 inch floppy drives.
Used the floppy drives to run CPM and wrote programs in Microsoft Fortran.
PS: Get off my lawn.
You want "personal"?
Maintenance manual for the mechanical targeting computer onboard Navy Ships:
Babbage would approve.
There's a big gap after Babbage - what about the various tide-predicting machines developed in the late 19th/early 20th century?
What about a mention for Hollerith and other related tabulators. They were the nearest thing to a computer before the 1940/50s and gave IBM their start.
Surely the World's first stored program electronic digital computer should be included.
Brings to mind also the evolution in the circuitry and silicon that goes to make the things up. Amazing to think that in less than 1 human lifetime (65 years this year) we've gone from the first transistor (Bardeen, Brattain and Shockley in 1947) to modern microchips. 1 germanium point contact on a desk to a few billion in a device that fits in your pocket.
I occasionally give a course to new recruits about the history of such things, including a few little nuggets for newbies:
* You can fit about 60 million modern transistors on a pinhead, and about 2000 across the width of a hair.
* If your house had shrunk at the same rate as transistors have, it would now be microscopic.
* In the time it takes to switch from ON to OFF, a beam of light would travel about 0.1 inches.
* Modern PGA chips have one transistor for every 2-3 people on the planet.
It's always a fun course to give, as it opens their eyes to quite the scale of what they're getting into (IC manufacture).
"(65 years this year) we've gone from the first transistor (Bardeen, Brattain and Shockley in 1947)"
Actually the Colossus used lumps of silicon with a contact wire a bit like a "cats whisker" to replace some of the unreliable valves, although not named as such and kept secret until 1970 they were in every respect transistors.
But Tommy Flowers is long gone and the records are in place and the awards awarded so Bell labs keeps the award. Perhaps it would be better to refer to their invention as the "first commercial transistor"
Well you learn something new every day :) That said given what a marvel Colossus was, it's not a huge surprise...
Indeed I was actually watching a (repeat) BBC Timewatch on the very subject last night about Colossus, Tommy Flowers and Bill Tutte. If you're quick (and in the UK) it's still available on iPlayer for a couple more days:
It's a shame that all the secrecy was needed - Flowers and Tutte should have their names up there with Turing and Babbage.
I have to say, I do like the history stuff El Reg runs every now and then. Roll on part two.
Other missing gadgets: the slide rule, the electro-mechanical desktop calculator, and the basic electronic calculator. All three might be excluded for not being general-purpose computers, but the same criterion would rule out Napier's Bones and the Difference Engine.
This just beat me to it. Here's my take on the earliest personal, portable computing devices:
Slide rules fully deserve their place in this history.
Several generations of engineers and scientists used slide rules, an essential tool from their invention in the early 1620s that remained in common use into the late 1960s. Arguably, these were the first portable calculation devices unless you want to include the far earlier, but less capable, abacus which, in its modern form, was in use from the 2nd century BC and printed tables of logarithms, which appeared in 1617.
However, a slide rule, though portable and deserving its place in every engineers' desk or briefcase, wasn't really pocketable. The Curta calculator gets that slot. It was far from the first mechanical calculator, but all its predecessors were heavy, bulky desktop machines, while the Curta was a comfortable handheld device and much loved by the rally-driving fraternity.
This was the first really good pocket electronic calculator. It was not only affordable, but a real game changer because it was the first that could replace a good slide rule, being capable of dealing with logarithms and trigonometric functions.
"a slide rule, , though portable and deserving its place in every engineers' desk or briefcase, wasn't really pocketable.
Circular ones were , at about the size of a drink mat
The rather more accurate helical ones were about the size of a mid-sized torch
I was using slide-rules well into the 70s
or HP65 as the first programmable, went on apollo etc
I was issued with a slide rule in my first engineering job, mid 80's, but only ever used it out of curiosity because we were just getting issued with one PC and the new-fangled HevaCAD software, about 6 grand or so.
BYOD then meant calculators. Still have the slide rule, but the old calculator is no more - IIRC a big clicky-keyed TI with red LED numerals. It took so many batteries that it was cheaper to wire in a 9v PP3 and stick it on top of the case with insulation tape. Replaced it with a Casio FX82, which I do still have. My attic is getting full.
We still dropped back to using log tables in our O-level maths exam even though we were using calculators for part of the course work.
Notable wartime mention - Alan Turing?
Apart from some of his work (which directly predicts what computers would be), the logic of the Bombe is undeniable (OK, not a multipurpose computer, but still important in the history).
The list seems to be missing the Turk.
i.e. a piece of technology which flim-flams the mentally challenged but during it's existence made a good deal of money for those involved. Tablet anyone?
Paris obviously because, although you knew she didn't, you thought about it.
Re: The list seems to be missing the Turk.
Tablets can actually play chess, the Turk only pretended to.
Re: The list seems to be missing the Turk.
Hiring a dwarf and sourcing a cardboard box for the few times I play chess now might be cheaper.
Surprised there was no mention of this:
I remember I was more impressed with that than with electronic calculators, back at school. It seemed natural that you press a button on some electronic gadget and it shows you a number. When "cold iron" calculated an answer - it was awe-inspiring!
computer techs were babes in those days.
What went wrong?
They still were in the 1960s and 1970s in the UK. As a junior I shared an office with five people doing technical support plus system programming for a major UK computer company. Four of them were women in their twenties. They delighted in making me blush - although they were nowhere near as bad as running the gauntlet in the all-women data preparation room.
The rest of the company's OS and application development departments had a high proportion of women too. Don't remember any women who were hardware engineers though. Women computer operators were restricted from working nightshifts. That didn't stop the women programmers coming in to see their jobs run late at night - and inviting the evening shift back for coffee at their nearby flats.
Somewhere is the 1980s was when women started to fade out of serious technical roles in the company.
They delighted in making me blush - although they were nowhere near as bad as running the gauntlet in the all-women data preparation room.
Oh, I remember those days. I was very young and it was - educational. You mean people actually do that?
"Onto the Desktop...
Excuse me? How big and how reinforced is the desk where THAT is a desktop?
What about the commodore Pet.
Whilst the Apple ][ had visicalc, the Pet was very common in engineering circles for conencting to IEEE-488 instruments. I remember seeing one in 1995, still quietly recording diurnal variations in the earths magnetic field, and pumping them out of the RS232 port. The software had been altered some time at the start of that decade to change the data format.
