ALGOL 60 at 60: The greatest computer language you've never used and grandaddy of the programming family tree

Andy A

First actual job was with 1900 kit. Ended up supporting our very own version of George 2.

So do you remember the significance of 7036875 ?

Andy A

ALGOL 60 was the first language I learned, in 1973. At Warwick Uni, they reckoned that virtually any science undergrad would need computer skills, so this was a compulsory course.

They ran an ICL 4130 and a 4120 at the time - designed by Elliott, so presumably somebody at Elliott was an ALGOL fan.

Never used it in any commercial setting, but it laid the basis for the structure used in any number of languages since. When writing COBOL, I often sketched things out using ALGOL to check things made sense before getting the coding sheets dirty.

Who remembers Backus-Naur ?

Re: An oldie, but a goodie

The predecessor to the Apricot in ACT's range - the Sirius 1 - actually DID have a bidirectional parallel port.

There was software (and matching hardware) which made it perform with IEEE-488 kit.

And no, you couldn't treat the serial port as though it was a minimalist IBM PC UART. It handled proper mainframe-style synchronous comms, with clock signals on 15 and 17.

Re: Proper lash up

The town where I live had for many years a sign near one end of the main street announcing "NEW ROUNDABOUT AHEAD".

It was removed about 6 months after the roundabout was replaced by a set of traffic lights.

Re: Uni days and laptop fans

Probably just time to clear the crap from the airflow. It's amazing how much fluff accumulates on the cooling fins even when you try to keep usage to "clean" places.

10 minutes with the usual screwdrivers and a brush usually suffice to get the temperature and noise back to the sensible range. Ignore it and the icon applies.

Re: In my day....

One pub I occasionally visited (when I could con someone else into driving) had a stock of various vintages of Courage Imperial Russian Stout - a wonderful 10% abv brew, made to a quality, not to a price. The recent stuff was well worth drinking, but I once had a bottle which was 30 years old and was like nectar.

Some years later I found a pub which had an odd bottle stuck behind their bar, and managed to extract it from them for what I considered an excellent price. It's a 1992 vintage, so just a couple of years to go!

No such thing as a "best before" date on beers of this strength!

I'm pretty sure I remember that event.. I was working with a small ICL mainframe at a stockbroker's site, inevitably positioned in the basement,

Suddenly we were left with just the emergency lights. No chance of a generator in anywhere near that old building.

The disk drives had impressive bearings - they stopped spinning a full five minutes later.

Panic ensued. Data had to reach the Stock Exchange before The Deadline or serious penalties would ensue, and there was now no way to generate the mag tapes.

80-column cards were found, and staff started the data prep, under the emergency lights - on HAND PUNCHES !

Working for the IT company rather than the broker, I headed off, carefully forgetting to mention my speed with a hand punch.

Because the power event hit so many offices, the Exchange actually decided to waive the massive fines for that day.

Re: "Microsoft scammers"

"If I've the time and in the mood I like to string these people on for as long as possible. I take the view that while they're talking to me they're not scamming someone more vulnerable / gullible. My record is keeping then on the line 45 minutes with them making another couple of follow up calls later the same day."

You are not alone in this quest, though I have yet to break the 40 minute barrier.

It matters not what the automated message says. It might be "Amazon auto-renew for 39.99" or "£600 has been withdrawn from your bank account", "your ISP will disconnect your internet" or any number of others. The aim is to get into your machine and steal stuff. In the olden days they had a minion who did the initial contact and passed you up the chain. The third person was the one you did the actual theft. Now the minion has been dispensed with because "$StupidStory Press One" is cheaper. The actual thief still doesn't know what the $StupidStory was. The person in the middle is tasked with working out whether you have stuff worth nicking.

Sometimes I try to talk about the place their phone call is supposed to come from. I used to look up the STD code, but these days they just spoof a random number and they don't know what that is. Today I feigned amazement that they had managed to get through because the news had just told me that "the whole of Doncaster is under 8 feet of floodwater" and that was where his phone call had come from.

Very occasionally I will even let them through to a VM which contains absolutely no useful data. It's a clean install and has visited no websites. It's a shame really, as I had told them I use Internet Banking and all sorts of other tempting stuff. None of them has yet noticed that the desktop wallpaper carries the VMware logo - a dead giveaway.

Once I have installed their remote control software (almost certainly full of malware), I sometimes announce that I have to go and answer the door, so they can get on with "fixing things" while I am gone.

They normally head for the saved credentials straight away. It is of course completely empty.

When I "return" a few minutes later I pick up the phone and ask if they are still there. "Good." I say. "There's a policeman here who wants to talk to you about computer-related crimes. He says that your local force should be breaking down your door any minute now."

Cue other end hanging up, and a swift re-image.

Re: Been there...

IBM used the same EDCDIC byte value for £ in the UK and $ in the states. That let them keep the same instructions to format currency values.

The code used to print the US cent symbol was re-allocated in the UK to print the dollar sign.

My first employer was a bureau using weird combinations of equipment, and I ended up writing all sorts of translations.

The absolute peak was a big data prep job for a brewery. The data was keyed on Data 100 key-to-disk kit (EBCDIC, with UK keyboards), then written to an 9-track, IBM format tape. That was taken from the punch room to the main computer room, where it was read by one of my programs on the ICL 2904 (6-bit characters). JCL was added and the result sent down the line to Birmingham, where it was processed on the ICL 2960 to produce a 7-track mag tape on the last 7-track drive our company had. That tape was carried to the brewery site to be read by a Honeywell mainframe, where it was read in as a "non-standard" tape, in the same way as tapes from their own, ancient, data prep kit. In the test runs, ALL the symbols came out correctly. The customer was very surprised - their own keyboards didn't have a UK Pound symbol !

Re: Delicate adjustment

Had a fault on an ancient OKI (ML184?) where it started off OK, then after about 15 seconds the print head slowed and eventually stopped.

I realised that the print carriage had done so many millions of trips back and forth along its shiny metal guide rod that it had an oval cross section rather than the original circular one.

This being an engineering place, a can of WD40 was to hand, and full speed head movement was reinstated. The folk there then gave it a quick spray whenever they changed the ribbon.

The ML320 boxes normally lasted about 3 months in that place, where the old printers were approaching the end of their second decade.

Re: Percussive maintenance

It was Rodime who made the drives for early hard disk Apricots.

They ran reasonably well until people arrived at work on a cold morning. They refused to spin up.

Investigation found condensation on the platters, and surface tension meant that the heads were acting as brakes.

The official work around, suggested by Rodime, was a thump on the right hand side of the case with the heel of the hand,

The heads bounced, and the platters turned!

Re: Percussive maintenance

Where I first started work, the site engineers had a device labelled "CPU REPAIR TOOL", those letters having been burned, probably with a soldering iron, into the wooden handle of an ordinary claw hammer.

When the processor developed one of those intermittent, irreproducible problems, they would remove the backs of the cabinets, then run the hammer smartly along the edges of the boards in the frames.

This reseated the hundreds of boards into their sockets in seconds, and the machine would run perfectly again.

Re: "...says the person who never dropped a deck of punched cards"

Once found a hand punch rusting away at another site. I grabbed it and rebuilt it, as they were like gold dust at our site. This one even had the little tab stops.

Having cleaned the rust off, it was time to re-assemble.

Imagine trying to line up TWELVE closely-fitting metal punches with their respective holes, all at once, with strong springs trying to stop you getting them in position.

I vowed never to do another.

Some models of card reader let you get away with thumbnailing a chad back into a mis-punched hole. One of the fancier ones though turned the card through a U shape ready to stack. They needed the little self-adhesive metal foil things. Otherwise PING !

Re: Reverse Penny-Pinching

At one of the sites I used to support, a lot of the higher-ups had to wander the world to their various sites. The official corporate line was to use major airlines rather than the cheapo budget ones.

So staff ended up flying to London and then off to Stockholm. Of course they could have travelled a lot cheaper from the local airport to Vasteras. In fact it would have cost even less than the 70 mile taxi ride from Stockholm airport to their site - in Vasteras.

I was once helping out by clearing a backlog of fault calls at a railway depot. Suddenly the PC I was working on went dark and all went quiet.

Enquiries revealed that someone up the road had chopped the BIG cable with an excavator, so it was not going to be a quick fix. I went to the server room and gave things a graceful shutdown before the UPS gave out. This was late afternoon after the office workers had left, so only the engineering staff were around. I headed over to them to inform them that I was heading off too, and commiserated with them that they would now be unable to brew any tea. "No problem" they said. "This buffet car gets its power from the overhead line".

Re: Mice are not particularly intuitive

-- A bit like cars - it took them a while to standardise the clutch-brake-accelerator layout, even the steering wheel from an initial tiller back in the days of steam cars. For anyone learning to drive it is not initially intuitive, but once you learn it's like riding a bike and you couldn't use any other layout.

As someone who owns a car with the accelerator in the centre and brake on the right, I have to say I found it quite quick to get used to. Changing between that and my "modern" car takes only a couple of seconds to flick the mental "switch".

I still cock up the odd gearchange on the crash box though.

Back in the early 80s the company I was with had a datacentre (multiple mainframes) in an industrial unit backing on to the West Coast Main Line.

They had to install a Faraday Cage to keep the mainframes happy, because the electric locos heading out of Euston could produce some hefty electromagnetic fields.

Luckily I was never there when the fire alarm went off - the emergency exit took you straight onto the tracks!

Re: With perfect timing

The number of traders who spam everyone whose email address they can get their hands on is very annoying.

I once used an email address to allow a company dealing in bathroom fittings to tell me when they would be ready for collection. They seem to have assumed that I would be refurbishing my bathroom at least three times a week. As soon as the goods were collected, they were added to the Always Block list.

I can count on one finger the number of traders reaching my inbox who get it right.

Having bought something for car restoration from an online trader which was difficult to source elsewhere, they started sending me their circulars, usually once or twice a month. All are about their special offers, are for different types of product, or are pointing me at a video showing their products being used. When I buy more items (about once a year), they recognise that I am already in their list, and don't send me multiple mailshots. When they asked me about GDPR, I happily ticked the box to continue the relationship.

Physics has the celebrated Pauli effect, where equipment suffers failures when a certain person is present, even if they don't actually touch anything.

The story is that some complex equipment at Gottingen unusually suffered a failure when Wolfgang Pauli was NOT present, and this unusual state of affairs was commented on. It turned out that Pauli happened to be changing trains at Gottingen at the time.

Re: Plug cable entry angle

That style of connector is only available for non-earthed applications, and seems common on phone chargers.

The "earth" pin is a plastic moulding; having a metal pin for electrical protection would require quite a bit of engineering. It would need to be able to guarantee electrical contact full-time, or disconnect the live pin in case of failure.

What amazes me is that virtually every UK 13A plug is shipped with a hard plastic "condom" over the pins. The pins need no protection because the plug is very robust. They are never live when unplugged from a mains socket. The only possible reason is when the paintwork on white goods might be scratched by a loose plug when in transit. Why did the cable for your last purchase of computer equipment have one when it was also inside a plastic bag?

Meters with displays? I remember them!

Swapping out the existing gas meter at my mum's house seems to have become something of a saga. The current device, not the first one to occupy the small cupboard by the front wall, lost its display about three years ago, its "10 year" battery having become exhausted.

There have now been over 20 abortive visits by various engineers. It seems that the neat 1990s model of meter has been replaced in the manufacturer's catalogue by one double the volume. Whereas in electronics, new kit is smaller and uses less power to do the same job as old kit, for gas the opposite is true.

The corresponding "smart" meter is bigger still - they say they only have one model, which presumably has to be able to cope with the gas consumption of a large factory rather than just a pensioner's bungalow.

The obvious solution would be to replace the meter with another of the same model fitted with a new battery, but it seems they carefully destroyed every single one.

Naturally, the supplier has been "estimating" the consumption, and they are really good at that, aren't they?

Re: Rubber bands

Last century I spent a while dealing with end-users and their faults. We tried to avoid sending an engineer half way across London for simple calls, such as "erratic mouse" reports.

Most of the mice were Microsoft ones, which were quite decent quality. The rollers were actually metal rather than the cheapo plastic ones.

Speak to the user and introduce them to the extraction of the ball of their mouse. "You see the two metal rollers?" "Yes." "You see the two little rubber wheels in the middle of them?" "Yes." "That isn't rubber. It's gunge."

Shortly thereafter, they could wander round their office earning themselves brownie points for sorting out everyone else's erratic mice, thus keeping our profits up.

Re: The thing is... it's nothing new.

The likes of ITV and Channel 4 force their ads when using their catch-up services. They disable the FF key specifically.

It's doubly annoying if you have a flaky connection, and replay gives up late in the programme. You are then forced to restart from the beginning because of their rubbish coding. Attempt to go to where you left off and you have to sit through the "ad breaks" from scratch again. Hoorah for the Mute button.

I eventually got the fancy key needed to open the windows. The concrete building pillar was HOT.

Restarted the switch and all was well. The ProLiant servers never missed a beat, though their monitoring logs showed the temperature spike in detail. Aircon 1 died about 8pm on Friday, with aircon 2 deciding to follow it 7 hours later.
