MicroMemories of a Silicon School Day

7 Jul 2015

Remember the BBC Micro? Tom Hargreaves does. Were they in your school, or maybe in your home? Thirty years ago these silicon stalwarts marked the first time computers became a common sight in the schools of Great Britain, and provided an introduction to coding that spawned many of the industry leaders in the current games and software arenas.

 

And now it's happening again. The BBC is gearing up to send out 1 million Micro Bit single-board-computers to schools around the country to give kids their first taste of coding delight. We're equally excited about the program, particularly because many us of were there the first time around and can vouch, personally, for the benefits of such initiatives.

 

Tell us about your memories of the Micro, ZX Spectrum or Commodore 64 and the early days of your computing awakening.

Computer Illiteracy

It began with a TV series. The class was ushered into the library and dropped in front of the school's TV at a very specific time one morning. It's not like we were watching a streaming video or DVD. The Computer Programme was on BBC2 in the mornings, and there was no other option than watching it during broadcast. That's just how media was consumed back then.

 

Actually, with the help of Google, I now know that it didn't begin with this dry and slightly confused TV show. The BBC’s Computer Literacy Project was a much broader and more ambitious initiative than a 10-part show squirreled away in the least prime time slot the BBC had to offer. I just didn't know this until a couple of years later, when I begrudgingly arrived at high school. (By the way, I love the phrase “computer literacy,” and mourn its loss. What a great way of mentally positioning the development of computer skills within an educational environment, right?)

 

It was a happy day when the telly was rolled into the classroom.

I’m peering 25 years over my shoulder, as I write this. We were still reeling from the wreckage of a country in recession, and schools had suffered a decade and a half of under funding. My school was only a few padlocks away from becoming a borstal. If you were kicked out of any other school in the town, they sent you to ours.

I only attended because it was the closest to my house, you understand…

 

Anyway, I only tell you this because the condition of the school was in stark contrast to the progressive nature of its computing department. At the back end of the 80s, most schools housed their computers the same way they did a TV and VCR; mounted on a wheeled trolley that could be ferried between classrooms for communist-style technology sharing.

 

Not us. At the back of the library and on the fifth floor of the humanities department were fully stocked computing rooms. Each gave asylum to at least 20 computers, not to mention a massive 20MB Winchester networked hard drive. And the computers? They were made by a company called Acorn, on order from the BBC (yep, the same BBC that now spends all its money on Doctor Who).

 

The 8-Bit Educator

This wasn’t a computer anyone had at home. Google might have you believe otherwise as we look back through a rose tinted monitor at the early days of home computing, but these were pure educational machines. Sure, one or two people had an Acorn micro, and a few unfortunate kids had wound up with an Amstrad CPC after their tech-blind parents failed in their Christmas research, but most of us either had a Commodore 64 or a ZX Spectrum (I proudly possessed the latter).

 

So it’s not a simple matter to divine the importance of the BBC Micro computer from 30 years hence. It might have been comparable in terms of hardware (superior, even), but in terms of its intended use, this was a very different beast. It’s remembered as an advanced teaching tool, rather than a home games system, and that’s an important differentiation to make when looking back at the BBC’s first foray into the world of silicon and software.

 

It sounds like I had no love for the BBC Micro, but that’s not the case. A computing class was like time off from the daily dentistry of 20th Century high schooling. It wasn’t learning, and it wasn’t a chore. Even the classroom didn’t feel like a classroom, because we weren’t facing a blackboard in regimented ranks, and we weren’t spending the lesson staring down at a desk. We each had our own pixels and cursors to lock eyes with, and a keyboard in place of a dog-eared textbook.

Computing That Doesn't Quit

I don’t entirely remember the lessons themselves, or the undoubtedly creative ways we put the BBC Micro to use (it wasn’t cool to pay attention, and as you’ve surely figured out by now, I was pretty damn cool). After all, I had a Speccy at home to play games on. What I realise now, and only in retrospect, is that the bucket loads of additional use I wrung from those rubber keys was due, in no small part, to the few school hours each week that I sat in front of the BBC Micro. It’s openness and accessibility leaked into my digital subconscious at that early age, and it’s stayed with me ever since. I’ve no doubt it’s the reason I can’t get comfortable with an iPhone, and opt for the more tinker-able Android instead.

 

What I also remember about the Micro, that’s always stuck with me -- and what makes me think the new Micro Bit is going to be a success of its grandfather’s equal -- is how indestructible those damn things were.

 

This was some seriously rugged kit, which took way more abuse from heavy handed miscreants than any piece of revolutionary hardware deserves. And this wasn’t just for a couple of hours a day; these things worked 40-hour weeks beneath the abrasive fingers of 2,000 hostile teenagers.

Remember the Micro? Tell us all about it.

The delicious, mechanical keyboard could take an impressive hammering, and still the keys never bounced or broke off. The casing was more like armour plating than delicate computer equipment, and the monitor could have been used to bludgeon a water buffalo.

 

Your MicroMemories of the Memorable Micro

Think what you will about the anachronistic BBC institution, and show the back of a derisive shoulder to the entertainment value of its 1980s Micro computer, but no one can argue that this was a machine built to last. If only all hardware was this durable we’d only have upgraded a couple of times since the BBC Micro was quietly retired.

 

Obviously the forthcoming Micro Bit is considerably smaller and probably more susceptible to cans of Coke and the frustrations of puberty, but it represents an equally robust way to introduce kids to a new world of computing. There are clear parallels between this new BBC campaign and that of my own distant youth, and it’s exciting to see if the effects will echo for as many years to come.

 

Keep the nostalgia boiling with your own micromemories right here on element14, and tell the world about your days at the incorrigible keyboard of the BBC Micro.

    Here is a picture of my Rockwell Aim65 in its home-made fold-out box with the lid removed. It is not even dusted off, but you can see some serious power supplies in the back (+24, +-15, +-12, +-5) and…

    Oh, NO! Look what getting all nostalgic made me do! "10 people bid - and you won! Congratulations!" We shall see, when it arrives, if it even powers up. Then I would need to locate an Atari 1050 disk drive…

    I started with a Commodore PET 2001 in 1976.

     

    I later upgraded to the Z80 based Big Board before beginning the endless succession of IBM/Microsoft machines.

     

    I also did a lot of work with 8085, RCA 1802, and TI9900 microprocessors at work.

     

    Lots of fun back then buy there were virtually NO tools or IDE like we have today.

     

    When I started working in 1972, I used a PDP 11-20 that required me to enter an machine code boot loader to start the paper tape drive.  The machine had a 7 track tape drive, a 64 Kword hard disk and 16 Kwords of ferrite memory.

     

    We did a lot of applied research with that machine.

     

    So nostalgia is fine, but like I said, the tools you have today are light years ahead of the simple tools I started with.

    I still remember the BBC Micro and the associated box-shaped monitors in a class room, but don't recall any school lessons incorporating them : (

    but I do remember it had a laser disc encyclopaedia for the UK.

    I also remember the Acorn Archimedes at school, because it had a demo game which was near impossible to control : )

    Some old book had this photo of a BBC Micro controlling a robotic arm:

    My first computer was a Sinclair ZX81.

    After I built it I couldn't resist the temptation to modify. So, designed some dynamic RAM for it. It worked for a while. Until, the power supply gave up. I then bought a VIC 20. Had a blast with it. And when the 64 came out, I was in nirvana. They had a deal where you would receive a $200 credit towards a 64 if you traded in you old computer. I brought them my ZX81. :-)

     

    They didn't specify so they had to go along with it. Good times indeed.

    Well I am with Mike on this one though, Age should not preclude us from participating in a little nostalgia and  I think I am even more years ahead of him lol.

     

    there was no such thing as a computer lab at schools when I left, and I actually started with Microprocessors in the 1974 era (4040, 8080 S100 etc) during my EE apprenticeship .

     

    My first computer i built was a 6802 programmed via a hex keypad and 7 segment display, I was 16 or 17 at that time, also Joined the "Newcastle Upon Tyne Personal Computer Society" and frequently showed off new addons to the members once a month when we met at the university.

     

    By 20 I was building Z80 based industrial control systems for British Gas to conrol the distribution systems in the north of England.

     

    Like I said, no computers when I was at school so all my early memories are between 16 and 21ish

     

    then I created the first expansion for a TANDY 80 that my boss owned

    imageimage

    adding a whole 48K more memory and user definable graphics (About 6 months before Tandy released their own). I guess I missed an opertunity there... ah well (Above is Tandy;s expansion, mine was in a wirewrapped card frame but linked in in the same way

     

     

    the first computer i built with an OS was the Bigboard II designed by Jim Ferguson https://en.wikipedia.org/wiki/Ferguson_Big_Board

    I received it as a bare board and a ROM BIOS and had to build it up from that.

    image

    one of the great things was having to code a Flopy disk formatting program in assembly so I could create a floppy the board could use, then modify CPM IO.SYS to work with this BIOS and then routines to copy from a APPLE CPM system, to the BBII, this involved inverting the data (Apple had decided to use inverting bufferers in their interfaces), hack in my IO.SYS and wrie to the new floppy. after that I could start to use the board. for its day it was very advanced and a lot of fun and became the first ever automated test equipment I built

     

    Ahh, those where the days, so long ago yet sometimes so fresh in my mind image

    My first computer was a Sinclair MicroAce.  It came as a bag of parts you had to solder yourself, and a TV interface module somewhere in the UHF range.  I learned alot from that kit, address and data lines, keyboard matrix, video circuits and memory chips.  I remember making a big stack of memory by soldering all the pins together while bending out the chip select pin for addressing.  I also spent many hours wiring up a Jameco keyboard to the Sinclair, only to have someone in my dorm room spill a big glass of rum and coke on it and making all the switches sticky.  I was the only one in my dorm with my own computer until the VIC20's and C64's came out.  We used the MicroAce in a play once to control the lighting board, One of my former instructors wrote a paper on it and published it somewhere.

    So many micros.........so little time....
