I wonder if anyone has a suggestions

a friend want me to copy the files off their LC II OS 7.5

My first thought was to run computer to computer (LC to a G5 OS 10.3.9) but of course LocalTalk does not work with ethernet.

Then I thought I would hook up a scsi cd writer to the LC - good so far until trying to run Toast 4.1 which just crashes the system (it is meant to be compatible with OS 7.5).

My next thought was that maybe I could hook up a usb external hard disk somehow but as far as I can see the cable adapters are for scsi peripherals to hook into usb and not usb peripherals to hook into scsi.

So I am seemingly left with taking off the files using floppy discs (assuming they are not too big)

I would appreciate any better suggestions -

G5 dual, Mac OS X (10.3.x)

    Hi,

    Since data files on an LC II typically are small (compression and maybe segmenting can be used, too), the easiest way would probably be to connect an external USB floppy drive to the G5. Use 1.44 MB diskettes for the transfers.

    Alternatively, if you have a suitable modem, install (via floppies from the G5 USB floppy drive or via a PC with a built-in floppy drive) a PPP program and a small email or ftp client or a server (e.g. NetPresenz) on the LC II, and transfer the files through the Internet.

    There are other methods. For instance, use a PC-style USB-to-serial adapter (often with a DB-9M output) on a modern Mac, and set up a direct link to the (serial) Modem Port of the LC II (over an appropriate cable combination). Standard terminal emulation software is used on both sides. Or, buy an Ethernet card for the LC II.

    Thanks for your sugestions Jan.

    Whilst the modem/internet suggestion is reasonable it will probably not be as fast as xfering to floppies and also will be expensive.

    The direct lnk with terminal emulation software is interesting but I am unsure about this as I think (but don't know) that this will merely enable the xfer of text and not programme files.

    An ethrnet card for the LC might be a very good solution but may well be very difficult to find.

    So I guess that the xfer via floppies will be the most likely solution althoug with 30mb of fiels is going to be very time consuming.

    Do you have any intermediate generation computers available like a G3 beige? Something that bridges the jump between the SCSI and non-SCSI (mostly) Macs? My beige can read SCSI drives, floppies, and SCSI peripherals (e.g., old Zip) as well as USB, Firewire, burn CDs.

    Generally speaking, you can transfer program files. Methods and protocols depend a bit upon the application used. ZTerm is an example of a shareware program for Mac.

    If you have access to a PC with a built-in serial port (DB-9M), you could even use that machine as an intermediary. All that is needed then would be a plain Mac modem cable (MiniDIN-8M to DB-25M) combined with a PC null-modem cable (DB-25F to DB-9F; sometimes you will find null-modem cables with both DB-9F and DB-25F connectors each end). Use something like the communications section of ClarisWorks on the LC II and HyperTerminal (part of Windows) on the PC. In case of transferring files via a PC, it is essential to encode (MacBinary or BinHex) or at least compress (StuffIt) any Mac program files. Otherwise, the resource forks of the Mac files will be lost. A data file (such as a word processing document) can (normally) be used with only the data fork intact.

    Thanks Jan for this expansion of your suggestion of using direct link with terminal emulation software.

    This looks to me as really helpful as I don't have to hunt around for something specific to the LC and also I could probably use this with any old mac even my original Mac 128!

    I shall certainly explore this and let you know how successful or not I have been.

    Thanks for the suggestion.

    Hello Robert,

    and also I could probably use this with any old mac


    If you have access to another old Mac with a round MiniDIN-8F Printer Port (see also the reply by Limnos earlier), it can be even easier. A normal Mac printer cable MiniDIN-8M to MiniDIN-8M can be connected directly between the Printer Port of e.g. an LC II and the corresponding port of the other Mac. That is a simplified LocalTalk network. Then enable AppleTalk on both machines. Turn on File Sharing on one (e.g. the LC II). Use the Chooser (AppleShare) on the other machine to connect. Finally, just drag-copy files from one hard disk to the other.

    If the other Mac has Ethernet, you could also (if you so wish, and if necessary) try the LocalTalk Bridge 2.1 software here, which would allow you to bridge a LocalTalk network to Ethernet.
