back to article Binary dinosaur drive found alive and breathing fire

A binary dinosaur, with another 28-year-old Seagate drive inside, is still working - in an original IBM 5150 PC's expansion unit. The 5150 PC accelerated the PC revolution kickstarted by the Commodore Pet, Apple II, TRS-80 (Trash 80), and other wonderful early boxes. The 5150 was a proper system, coming with a keyboard, built-in …

We might be able to beat that...

Does an Tatung Einstein or BBC Micro count as a PC given that they were called Home Computers on release? If so, then I might be able to beat that assuming they still work, and we haven't binned them. They don't have HDD's though, just pre floppy disk drives

Re: We might be able to beat that

Ditto. My BBC Micro was bought as a model A with 32k (because the B was in short supply at launch), still works, although I did replace the original linear PSU about 20 years ago when a nice switch mode crossed my path.

Somewhere I have some disks for the viglen 40/80 switchable 5.25 floppy drive.

Amongst the collection of ancient technology I also have two Einsteins, but unfortunately no floppies for them... Stupid 3" non-standards! Grrr! They were a rescue out of curiosity, so I have no idea if they even work!

I have a Z80 based pc from around 1980

My company's home computer club designed and built a z80 based home 'pc' as a kit of parts. It had max of 48k ram and ran crystal basic. a couple of brave souls got cp/m running on it. It's still downstairs and it worked when I last switched it on about 8 years ago. It generates a composite sync output from character mapped RAM, and needs an ICL 7500 series keyboard - not sure that's still there though!

I tracked the motherboard, debugged the design and wrote the bios. 2kbytes? or maybe 4k? can't remember which.

Suspect many of the caps will have died by now though, so could be exciting to switch it on!

Tantalum caps

Little sods those tantalum capacitors. They can be quite destructive when they fail, and need replacing sooner than any other component I can think of. Just had to "recap" the PSU on a 30 year old synthesiser - a very tedious task.

Old Machines

My own collection contains at oldest a BBC Master, a Mac Plus and a Mac Classic 2.

Master and Plus are mid 80s I believe, and hard-drive-less. Classic 2 is early 90s.

Data retention from machines nearing 30 years old is going to be an issue. Books can survive for centuries, but gigabytes of data from old HDs and floppy disks is lost forever, in most cases as early as 10 or 20 years.

FOSS is not the silver bullet.

With FOSS, you might know the format, but can you compile a program to read it? If there is a binary will your system libraries be compatible? Will it compile with the latest version of gcc, and if not will you be able to install an earlier version of the compiler to compile it, or will you build a cross-compiler, using some script you dug up from somewhere, that relies on downloading a source package and accompanying patch from a site that's long-since disappeared. Or will you just go back to an older version of Linux, the one that was used to compile *that* version of the program by the original developers, but then find out that, oh bugger, it doesn't support SATA or ACPI (properly) and needs this and that to install, and won't even install in a virtual machine due to some obscure VM bug or incompatibility.

I'm as much a FOSS enthusiast as anything else, but it reaches a point where the old closed source version is actually easier to obtain and run than the old open-source equivalent, particularly if it uses a fairly well defined standard like DOS or Windows API.

So FOSS helps a bit, but not as much as you'd think.

No, but it's at least bronze...

> With FOSS, you might know the format, but can you compile a program to read it?

Yes.

I might have to modify the program first, you're certainly right on that account. But the point is, with FOSS I have that option.

So at first, the ease of recovery is probably proportional to how large the installed base used to be, I agree. But after a while, exactly when the nasty scenarios you paint start to bite, having the source will win out over praying that a binary is still somehow runnable.

If you're not a programmer yourself, you might have to hire one, but again, the point is that you have that option.

Well-defined standards

I don't think "DOS" and "Windows API" fall in to that category.

If we're talking about hypothetical situations where compiling FOSS source code causes issues, I doubt that a closed-source set of architecture-dependent binaries is going to be working for your closed-source application.

I like what you tried to argue, I just think it's rubbish: with source code, you could eventually adapt the old app to work against new arch and libraries, or even reimplement it completely in Java 31.

Norand Sprint 100 ?

I think this little bugger is pre-1980, but I haven't found much info on it on the net.

Handheld, 12-segment LED display, alphanumeric keyboard, one-way accoustic modem.

Other than that, my Epson HX-20, should also qualify as it's from 1982.

(2 x 6301 8bit CPUs, one of which was dedicated to IO, so even at .6MHz, this thing was fast.)

The sinclair ZX-81 is also still ticking and kickin. My Casio FP-200 might qualify, or not. Can't remember if it works or not.

My HP 9816 workstation probably doesn't count as it doesn't boot. (I just don't have a boot disk for it.)

Keyboard, because the HP 9816 lacks a few keys...

Re: Format

This is not exactly news.

Thing is, what makes data survive isn't the medium it's written on. What makes it survive is *LOTS* of copies of it, widely distributed. And even then, you might need to get lucky.

The Rosetta Stone was just one of hundreds of copies of this multi-lingual text; according to Wikipedia, precisely three copies have survived, all in somewhat dubious condition. The burning of the Library of Alexandria destroyed the vast majority of everything known about Greek history, technology and culture - the only vestiges of Greek thought to survive were those bits which the Catholic church approved of and had copied. With the fall of Rome, almost everything about Roman art and technology was lost for the same reason - the church approved of studying Roman history and philosophy as the source of Christianity, but didn't care about their art or tech. Bede's work only survives as copies, all of which are different, and there aren't too many copies of that. A decent chunk of Shakespeare's output hasn't survived, never mind stuff written by his less-famous contemporaries like Jonson.

So don't rely on stone. Don't rely on paper. Don't rely on magnetic media. Don't rely on optical media. Rely on a *process* of regularly copying, and spread those copies around. Then when everything goes tits-up, chances are that at least one copy somewhere is going to survive.

BBC Domesday book

As I underastand it, the laser disks are physically fine, but there is nothing available to read them!

I haven't googled this yet -going off a memory of something I recall reading in c2005/2006, but the issue was the laserdisk player used custom code, so the few players available [even then] were unable to be used. In addition, a BBC Master 128 was required to run read them...

Must google and see what the outcome was. I seem to remember a BBC spokesperson commenting that much of the project involved recreating the content from scratch...

Not just custom code...

It overlaid text (generated by the BBC micro attached to the disk player) over photos from the disk, and ISTR it synchronized the two video streams by varying the disk player motor speed.

I also STR there were various "consultant" types involved with the project.

Domesday project

Whilst the BBC Domesday project serves as a warning of what can go wrong with archiving digital data, this shouldn't mean that digital storing is always doomed to failure. The project failed not because it was digital, but because of stupid decisions - that should have been clear were stupid even at the start ("Yes let's make it only readable on one platform, clearly that will be around forever").

If someone today proposed storing data in a custom closed file format, on USB sticks, only readable on OS X, the pitfuls should be obvious.

It's like the original Domesday project being done by someone using a pencil to write on toilet paper, and then when the results are unreadable a few years later, proclaiming that paper is useless for storing information.

This is very unfair!

Hardly "stupid decisions". Remember how long ago this was!

Back in the days of the BBC Domesday project there were no open standards, there were lots of platforms, none of which were in the slightest bit compatable and the people concerned were having to create pretty much everything from scratch.

Couple of old PC clones still going here...

Most notably, I've got a Zenith Data Systems PC (8088) and a Kaypro Professional Computer (8086) that are both going strong. The Zenith is floppy-disk only territory while the Kaypro had a Seagate ST-251 hard drive installed sometime in the early 1990s, or so says a printout that I found tucked in the bay above the drive.

The ST-251 still works well, yet due to its use of a stepper motor to drive the read/write heads around and its tendency to drift out of alignment due to changes in climate and position, it needs to be low-level formatted.

I had some other "neat stuff" in my collection, including a fully functional Apple III and a fully loaded Apple IIe. Too bad I had a basement flood that washed it away.

Gah

I had a 5150 machine back in '92, which my dad asked for (and got) when his company chucked it out in favour of a new-fangled PS/2. It only had a mono screen (MDA), had two floppies and no hard drive. It couldn't play many games and thus was thrown out a couple of years later when we got a 486.

If only I'd kept it!

(I still have the clicky Model F keyboard, which I kept because it was great to type on and I thought I might be able to use it with newer PCs. Hah! I also have the floppy controller card, as it has an external floppy drive connector - I've never seen anything that could plug into it, but it seemed interesting enough to keep).

Mine were Amigas

I wasn't able to afford an Apple II when they came out. I could only drool.

But, in 1985 when the Amiga 1000 came out, I had a job, and so could afford one. It had the memory expansion card that took it up to 512K, along with a second (external) floppy drive and the CBM multisync monitor. Next was an Amiga 2000, which I later upgraded to a 2500 (68020 CPU). Then came the Amiga 3000 (68030 CPU). Since I was doing lots of work on my Amigas, I took the unusual step of buying an A4000T (68040 tower) a few days *after* Commodore shut down.

In searching for more space here, a couple of weeks ago I finally decided to get rid of them all. First I tried them out. All still work, although the 3000's hard drive is a bit flakey in some spots. I ran my AmigaMUD server on the 4000T, had the 1000 and 3000 connected with serial ports, and for a couple of hours 3 of us bashed around on it. The 4000T and the 3500 went to a friend's storage area first. I played another game of mine on the 3000 until I would have needed to draw maps. This past weekend, the remaining two and the monitor when to storage as well.

I will miss the machines, but I really wasn't going to use them, and need the space.

Maybe I could beat this

I have something called a Texas Instruments Silent 700 data terminal (Yeah, it's not a functioning computer just a terminal) with a built in keyboard.

No screen but it has a thermal printer built in and an acoustic coupler. I have just tried it now and it powers up and the printer still works (Plenty of paper on the roll still!)

I have no idea when it was made but looking around the 'net suggests these were first built in the early 70s.

My office is full of old junk like this hidden away.

Silent 700

Early 70's would be right - at school we had one of these and a breadbin size modem to call up Salford University's mainframe. The terminal also had two nifty cassette drives on top so you could type programs in advance and "download" them to the phone line...

The printer was thermal, I think eventually the heads failed so dot matrix became dotty lines.

Speccy

Not too interesting, but I have a few old ZX 16K/48Ks with voice synthesizer, thermal printer, and microdrive.

These were my home computers growing up (we had multiple due to the number that stopped working).

I got the whole lot (with 50-odd tapes and microdrive "disks") out of the loft about 10 years back, but all of the microdrive disks were dead (no surprise) and I couldn't get most of the tapes to fully load.

The Hobbit worked, if I recall, and it really made me appreciate how patient I used to be to play any of those games.

In the end, the Speccy emulators are superior to digging up the real deal (IMHO).

Almost forgot: how awful were the keys on those units, though? eh? Crazy little rubber things

And what was with 5/6/7/8 being the arrow keys? Threw me off for ages trying to play things like Dan Dare.

Old stuff ...

My completed in 1978 Heath H11A still works. Two 8 inch floppy drives, but no hard drive. Like the above poster, I laid out the traces & boiled all the boards ... Mom was really pissed off at the mess in her kitchen, even though I cleaned it up when I was done ...

Does my Sun1/100 (pre-Orange logo) with four CDC Lark 9455 drives count as a Personal Computer? Mine is dated late 1982 ... It was scrapped and given to me by a Sun field service rep in 1989 or thereabouts, and even then it was old fashioned & kinda klunky. It still boots, and I just compiled "Hello, world." on it, so I guess it still works :-)

I have an IBM 1405 Disk Storage Unit dated 1963 that still worked when I plastic-wrapped it and packed it and misc. other bits & bobs (1402, 1403, cabling, documentation, some card decks, etc.) into shipping crates nearly 35 years ago. They are awaiting the completion of my 1401 restoration project ... IBM wouldn't let me have the 1401 back then, but were happy to allow me to cart away the "obsolete" peripherals. It took me almost 30 years to find a suitable dated 1401 to complete my set. Hopefully the stuff still works. It's technically a "small business system", not a personal computer, but it only had a single user/operator, so if you squint it could be considered a PC ...

I have various other functional old computers down in the museum/mausoleum, but none of them could have been considered "personal computers". Why? Why not :-) Some people collect stamps, I collect and restore obsolete computers.

My dad has a working Altair 8080 by HeathKit from 1974 or 1975, I don't think he uses it any more. I can remember playing StarTrek on it in 1976.

The only other thing I can remember is being told not to flip the toggle switches on the front if I wanted the game to keep working...

I know that he used this computer productively until at least 1988, admittedly as a glorified print spooler. The only part of his Terminet 1200's that wore out were the ribbons and that's only because he and my younger brother build an auto-inker, well, a manual auto inker that was simply a 15 minute timer so when it beeped, he knew it was time to put another drop of ink on the cartridge wick.
