Retrieving Data From Old Amstrad Floppies? 323

Posted by timothy
from the but-I-thought-you-said-it-was-obscure dept.
Jeppe Utzon writes "Back in 1987, when I was a teenager in high school still, I spent most evenings, nights and weekends writing small programs in BASIC on my Amstrad CPC 6128. Some of these programs were simple games, some drew graphics, some could help me with math or train me in French — and most were utterly pointless. But I never had as much satisfying fun as when writing those programs — even if no one in my family understood any of it when I proudly displayed the fruits of three sleepless nights of labor. Now, 20 years later, I still have a sealed pack of about 15 disks with all my work on them (along with a few of my favorite games) and I was wondering if it was possible to get the data out somehow so that I could run it in emulation on my Mac. I know of the emulators, but have no clue what would be needed to extract the data — or if it is even extractable after all these years. I realize the chances of the data still being intact are quite low, but I'd like to give it a shot. So if anyone has any pointers it would be greatly appreciated." A large hurdle will be finding a drive to read the Amstrad disks at all.

          It depends on the platform.

          IBM-compatibles used a special floppy interface - the controller is on the motherboard.

          And, if a modern PC has the hardware to drive a 3.5" floppy, it can drive a 5.25" floppy. So, yes.

          But, the IBM-compatible floppy controller might not be able to handle these Amstrad disks.

          Assuming he means a PC 5 1/4 inch drive, 5 1/4 inch drives connected to the floppy controller, which remained basically unchanged in the switch to 3 1/2 inch drives. Modern motherboards still generally have a floppy controller; if your PC has a 3 1/2 floppy drive, it'll support a 5 1/4 inch drive. My PC actually has a 2-in-1 drive hooked up in it, so I can still read and write 3 1/2 and 5 1/4 diskettes even today.

          I've got a combo 5.25"/3.5" drive... fits in a standard 5.25" drive bay. Modern computers do support it, but only one of the drives is seen. I need to set a jumper on the drive to switch between the 5.25" being A: and the 3.5" being A: in order to use it.

          I've used it as recently as a month ago, when it was the only floppy drive I had lying around and I needed to flash the BIOS on a new motherboard so it'd support a quad core processor.

      You're a programmer, get your hands on some old hardware and take advantage of what wikipedia says:

      Serial port adaptor

      Amstrad issued two RS-232-C D25 serial interfaces, attached to the expansion connector at the rear of the machine, with a through-connector for the CPC464 disk drive or other peripherals. The original interface came with a "Book of Spells" for facilitating data transfer between other systems using a proprietary protocol in the device's own ROM, as well as terminal software to connect to British Telecom's Prestel service. A separate version of the ROM was created for the U.S. market due to the use of the commands "SUCK" and "BLOW", which were considered unacceptable there.

      Use a serial line to copy the data. I'm sure that it wouldn't be too hard if you can just get a machine that works.

      • If I remember rightly the drives were integrated into some models of Amstrads. Given this if you can find an old Amstrad you should see if you could create a serial link between the computer and your Mac. After that its a matter of using kermit or some other serial transfer protocol.

        Yup--Amstrad was one of the makers of oddball "semi-standard" PCs. It had standard serial ports that others like Atari and Commodore seemed averse to using on their 8-bit home computer lines (probably because they wanted to make it a hassle to use third-party peripherals--basically buy aour stuff, or buy an overpriced adapter to plug in standard stuff).

        Amstrad CPCs not only had the same floppy controller and interface as the IBM PC, it also used the same 6845 video display processor as well (which is why it had CGA-like graphics, and the added 16-colour low-res mode like the Tandy 1000 series and PCJr). Sound was identical to the MSX-based computers. They basically cherry-picked here and there.

        Too bad the use of a non-standard form factor drive with the standard connector had to happen though. What's this guy going to do with the old discs now? Fortunately for myself, I purchased a floppy drive for my Coleco ADAM the first opportunity I could because the modified cassette tapes were not all that reliable and they were hard to find. As a result all my old stuff ended up on floppies.

        The Coleco floppy drive had a non-standard ADAMNet interface (ADAMNet worked just like USB but slower--you could plug the keyboard into the back of the disk drive, or the front "keyboard" port, or swap the floppy and keyboard wires and the damn thing would work). More importantly though, the disks were normal 5.25" floppies FORMATTED TO A STANDARD 160KB FORMAT READABLE ON IBM PCs. Eighteen years after we got the ADAM I was able to scrounge up a leftover 5.25" floppy drive, put it in my Linux box and use DD to make images of the floppies that work perfect with emulators!

        Interestingly Atari kind of migrated towards less-proprietary architecture with its ST line too--ST computers had standard serial and parallel ports, and it used 3.5" floppies with a variant of FAT formatting that was readable on IBM PC drives.

        I was laughed at by Commodore and Apple fans for going with "toy" Coleco and Atari computers, but in a sense I got the last laugh, because I ended up with computers that had amongst the most easily recoverable media of all those computers of that era. So why did I choose the Coleco and Atari ST computers back then? Becasue both could be easily made to run a variant of CP/M, including popular apps like Wordstar.

      What are the chances someone could hack themselves a disk drive that could read these? It seems like it would be possible to rig up some sort of magnetic scanner that could read the analog magnetic domains on the disk, and convert that to data in software. I'm sure it would take some crazy engineering, and it's probably not worth doing, but it at least seems plausible.

    It should be trivially easy to do, given a short BASIC program and five minutes on ebay.

    Just search ebay for an Amstrad CPC6128 or a Sinclair Spectrum +3 or an Amstrad PCW. There are still plenty of them around. (I have a Spectrum +3 with a working 3 inch Amstrad floppy drive as it happens, the floppy drive is quite handy for restoring the firmware on the Spectrum ethernet card I'm developing if I blow some non-functional code onto the flash ROM and can't reprogram it any more over ethernet). It would be best to get a CPC6128 - if you get a Spectrum +3 or a PCW you may have to write some low-level software to read CPC formatted discs.

    The CPC, if I remember right, has an RS232 port. Write a short BASIC program to send your data to a PC via RS232.

    Incidentally, the most common fault on the 3 inch Amstrad drives is a broken belt - you can buy new ones from rwap software: http://www.rwapsoftware.co.uk/ [rwapsoftware.co.uk] - while this firm caters for the Spectrum, since the later models were built by Amstrad with the 3in drive, they carry parts for 3in drives.

    The other good news is most floppies seem to hold up well - while the 3in discs don't seem to do as well as 5.25 in discs (I have only one faulty disc in many 20+ year old ones for my BBC micro, but rather more faulty 3in discs - all pre-recorded game discs) - so I suspect your discs will all read fine.

Given that they have to do things like mount naked platters and floppies and read them as-is, it seems likely that their gear can accomodate a range of different sizes and sector layouts and whatnot.

      A note: Before you start looking down this path, be sure think long and hard about how much your nostalgia is really worth.

      I recently did just this with all my old 5 1/4" disks. I had about 200 disks full of old games, programs, and some Basic work I did. The whole "514" project took me an afternoon, and 34.6MB of space. I was surprised about how many of the disks were still viable after 10-15 years.

      Except for one particular brand name of disks. I don't recall which one-- but let me tell you this: Of the 200 disks, there were maybe 4 I really, really wanted to recover. The ones that had some Basic programs and animations I had done. And wouldn't you know, the only three that were corrupt were from that pool of four.

      I still have them, just in case. But a cursory glance at data recovery places let me know that they'd charge anywhere from $75-$300 per disk. If they don't get it right (or if they're a crappy place as screw up the procedure) the data is for-sure gone forever.

  • I've attempted to read 10-year-old 3.5" floppies and had pretty bad luck. The magnetic media became unreadable, at least on my standard equipment (which I tested and works just fine with fresh media). Perhaps a sophisticated lab could get the data off, but I sure couldn't. You may find that your disks are unreadable by now, even if you had equipment capable of reading them.
    • Been there, done that. I was going to fire up my old Amiga 3000 a few years ago. One that had the original kickstart on a disk instead of rom. Dug out the disk and blew some brown dust out from under the floppy then I realized that brown dust was the magnetic media flaking off. I actually blew away my own data.

    • Purdue University Computing Center used to have a bunch of NeXTs with optical drives. You might be able to find someone there that could do the conversion for you for a small fee.

    It is possible to connect an Amstrad 3" floppy drive to a PC computer. Both CPCs and PC computers use the same type of floppy disk controller. You can get a suitable drive by purchasing an old Amstrad PCW word processor device. Here is one application for reading the disk format on a Windows system:

    Several other similar tools exist.

    Here are instructions on connecting a 3" drive to a PC:

    In which case, I did this just last weekend. It's not easy though. Requirements were:
    • 1 Amstrad PC (with floppy drive)
    • 1 PC running Window 98 with parallel port
    • 1 copy of Locolink, which includes a parallel cable and transfer software

    In my case we had an Amstrad PCW8256 in full working order, so that covered reading the disks. The Locolink software is hard to come by but I picked up a copy on E-Bay. It's designed for transferring and converting Locoscript [locoscript.com] files but will transfer other files as well just fine. It only works with Window 98 on the PC side though.


    If you don't have an actual working Amstrad then your best bet is probably finding a hacked-up 3" drive that you can connect to a PC. You might be more likely to be able to purchase the whole computer.


    If you're in the UK there are services that will transfer the files for you for 10GBP a disk. Here's a list [diskdoctor.co.uk] of them. In the US, try here [ukonline.co.uk].


    Good luck!

  • Even though I never had an Amstrad to recover disks from, I somewhat regret not having bought one of the three or four I saw at thrift stores over the years. As long as the interface is compatible with the standard Shugart interface (which it should be), you could hook it up to a Catweasel card. I did buy a few Amstrad disks when I found them (they were small), but by the time I cared, I didn't see any more of the computers.

    But I was a TRS-80 guy back in the day, so all my old disks are already imaged than

    Ebay has them galore but not exactly cheap:

    Just the drive (got an old AT style PC) here: Ebay! [ebay.com]

  • I don't know what kind of interface the 3" drives have, but if it is or can be adapted to the usual 34-pin SA400-style interface then one of the Catweasel floppy controllers (made by Jens Schoenfeld A.K.A. Individual Computers) might be your friend. They can make reading almost any format a Simple Matter Of Programming(TM).

    My first programming was on punched paper tape, which I can still read. I am not saying I have a machine that could read it, but at least I can look at the punches and figure out what the characters were.

    When I was in grad school, there was some data stored on punched paper tape, stored fan-folded. The tape had dried out and cracked where the folds were. (The cracks would be in the middle of a byte, especially a high one, as they would have more holes punched in them.) They wanted to save the data, so they hired a under-grad to spend all summer sending the tape through a reader, one 4 foot section at a time, figure out what the byte was where the crack was, type that in, and then proceed to the next 4 foot section. I still think that that must have been the worst IT job ever.
  • The Amstrad PCW, Amstrad CPC and Sinclair Spectrum used the same disk drives. For example Level 9 published triple-format (!) disk versions of their adventure games that could be played on all the above. If you're looking to buy a second-hand computer to read your disks, this may increase your options.

    Oh how I wish I hadn't thrown away my Amstrad CPC 464 three years ago, or I would have been able to actually help. I had an external 3" disc drive that was connectable to a PC in lieu of a 3½ floppy.

    There just wasn't any way I was going to be able to get it back to the US from my parents' attic in Britain and I didn't have time to dispose of it properly on eBay, so off to the skip it went.

    I feel sad.
  • Ask about on Usenet - comp.sys.amstrad.8bit, and on CPCZone http://www.cpczone.net/ [cpczone.net] and look on the CPC Wiki http://www.cpcwiki.com/index.php/Main_Page [cpcwiki.com].

    People there have working CPCs, and setups to get disk images from the CPC into a .dsk file on the PC.

    keep looking on ebay for an old cpc 6128 or PCW-8256 or PCw-8512 (they all had the same 3" Hitachi microdrive). You can probably pick one up for like 10 uk pounds or something,

    The Hitachi 3" Microdrive which was intended to be a direct competitor to Sony's 3.5" format. (Unfortunately for Amstrad the Sony format was the one that won-out in the PC world). Because of that I'm guessing the possibility that the 3" Microdrive has a PC-compatable connector may be high (but I don't know for sure).

    Of course even if you got the drive connected to your PC OK still the problem would still be to get your PC to recognise the AMSDOS file system on the floppy.

    I guess another option (if you get your hands on an amstrad computer) would be to write some little program that implements a simple file transfer protocol via whatever ports (RS-232 etc) that are available on the amstrad you get, then connect it directly to a regular PC via a homebrew cable.
  • My first computer was a 286 running DOS, so I'm not in quite as much trouble WRT finding machinery to read my old code. That being said though, I've been religiously bringing my old data forward as different storage formats have become obsolete. My 5.25" disks got copied to single-sided 3.5", then dual sided 3.5", then CDs (briefly) Zip Disks and now I'm in the process of moving my archives to DVD. I'll be amazed if any of this crap is ever of interest to anyone but me, but I find it fun to go back from

I had a chance to buy one of the BBS' I would play on and I tried to get some old friends to get back with me so we could relish in the glory days. It was awkward, not that much fun, and
  • I have long since thrown out my commie64. I had roughly 200 5 1/4 floppies loaded with c64 games and other apps. I was hoping to sell them on ebay. But my parents tossed out the floppies a few weeks ago.

    now all I have left is that old star micronics dot matrix printer for c64.

    I need to get rid of that thing.

    Using Google, I fouund the solution. It appears that this guy [netfirms.com] can do the conversion for you and return your data in hours. Cost would not be prohibitive and would support the Amstrad addiction.

    He seems to have a pretty good handle on all the conversion problems, too. His page is a fun read just for that.

    ddrescue [gnu.org] is an open source disk recovery tool based on dd. It can make a disk image from any kind of disk, regardless of format and it is designed to be very robust reading through bad blocks as you're likely to have on disks that old. You just need to have a floppy drive to connect to. ddrescue will compile and run on Linux, OS X and maybe Cygwin.

    Once you have a disk image, Foremost [sourceforge.net] can extract files from it. It is also open source and can be compiled and run on many different platforms and doesn't care about the filesystem on the disk image (or original disk). It searches for files based on header information. If need be, you can edit what header information it looks for. Since your BASIC source code is, presumably, ASCII text files, it shouldn't be a problem.
