Q: Transfer TIFF files from Macintosh IIsi to Windows PC
-
May 2, 2013 11:20 AMby Jan Hedlund,Hi Jim,
Basically, you would have to create a new direct/local connection using the same settings as for the PC counterpart (for instance, HyperTerminal). Select the Modem Port on the Mac and COM1 (or another appropriate port) on the PC. 8 data bits, parity none and 1 stop bit would be standard. Hardware handshake is typically the best solution. but you may want/have to test both Xon/Xoff and no flow control. You could test something like 9600 bps speed on both computers to begin with. If successful, try higher speeds. The transfer protocol ZMODEM if possible (otherwise, for example, XMODEM).
Do expect problems. Be prepared to experiment. Setting up a null-modem connection for file transfers can sometimes be very irritating, partly depending on which programs are involved. If you do not know whether the null-modem adapter/cable is OK, you may want to send text (in a terminal mode), perhaps with local echo turned on, as a cable test. Never connect any cables with the computers turned on. Carry out all connections at your own risk.
If it does not work, do try other programs. An Internet search should provide you with more information regarding settings et cetera. See also the Windows help under HyperTerminal and the ZTerm instructions.
Good luck!

Played around and tried different choices, eventually able to transfer text file from PW180 to PC intact, also able to transfer 1 picture file to PC but it is unable to be opened by "Windows Picture and Fax Viewer"
Was the picture file corrupted?
Please advise.
Many many thanks.

I also downloaded a Tiff Viewer called BravaReader and put it on my pc. When I tried to view the transferd Tiff file, the message "Format not licensed. This file format is not licensed or an embedded file is not licensed. Contact Infornational Graphics Corp for licensing details." and the picture could not be viewed, even though the file on the side of PW180 can be seen.
Does this mean transferring missed some information?
Thank you for advising.

May 3, 2013 4:13 AMby Jan Hedlund,Hello again,
Jim, there are several TIFF types/versions. This could lead to difficulties finding a suitable viewer. Someone here may possibly be able to help if you post additional information about the program in which the files once were created.
Generally speaking, the data fork of a Mac document is usually what is needed for a file to be read by a program on a PC. The resource fork, which gets lost during the transfer to/on a PC, is required for Mac applications et cetera. For example, if you try to pass an unprotected sea file through a PC, the file is not going to be self-expanding any more. For protection of Mac files in transit via a PC to another Mac (in order to preserve both resource and data forks), an encoding is used (MacBinary or BinHex). I guess that this should not be a problem for your TIFF files, though.
Could you transfer one TIFF file from the PB 180 to the PC on a 1.44 MB floppy to see whether you get the same result as with the null-modem transfer?
From the PC, could you send one (not encoded) TIFF file on to the iMac (via email or on a USB flash memory drive), and then try to use Mac viewers there? The shareware program GraphicConverter should be able to handle most image files. If necessary, as a pure experiment, the transfer via the PC to the iMac could perhaps later be repeated with a file that has been encoded for protection on the PB 180.

1) TIFF file from PB180 to PC by floppy disk can be viewed on PC with "Windows Picture and Fax Viewer" and BravaReader normally;
2) On iMAC, TIFF files from internet to PC to flash memory can be viewed normally;
3) On iMAC, my TIFF photo files from PB180 to PC via nullmodem cannot be viewed;
4) On iMAC, my the text file from PB180 to PC via nullmodem can be read by Word.
Does it mean null modem transfers text files fine but TIFF files are changed when going through null modem transfer?
I also tried Xon/Xoff and Hardware Handshake, both gave unviewable photo files.
What to try next?
Many thanks.

Thank you so much for your directing me to the file conversion menu so that I tried binary and HAHA! Everything clicked! I successfully transferred the TIFF file from old Mac to PC and am able to view the photo with "Windows Picture and Fax Viewer"! It looked exactly like it on Mac!
Thank you SO SO MUCH!
Below I summarize my experience in the hope that it can help others with similar needs:
============================================================
My need: I have hundreds of TIFF family photos on Powerbook 180/Mac IIsi and I wish to transfer them to PC for better access and sharing.
My equipments: Powerbook 180 (system 7.1) and Mac IIsi (system 6.0.8) and PC (windows XP). The Macs have not Ethernet card or internet access or CD drive; the PC has all.
Jan advised me to obtain:
- (Mini DIN-8M to DB-25M) and (DB-25F to DB-9F) under $5 each from ebay;
- zterm-101.hqx from http://ftp.funet.fi/pub/mac/info-mac/_Communication/_Terminal/
- If there is no Stuffit Expander on Mac to expand zterm-101.hqx, you can go to http://rrzs42.uni-regensburg.de/Macintosh/files/macftp.html and eventually get one for the Mac. (Jan’s instruction: If no appropriate version of StuffIt Expander for Macintosh is available, you may want to try this: Use a PC to download the MACDISK.EXE file mentioned in the web page below. Prepare an empty PC-formatted 1.44 MB diskette via FORMAT A: in DOS or the full formatting option under Windows (important). Do this even if the diskette is new. Run the downloaded MACDISK.EXE program on the PC. Follow the on-screen directions. The result will be a floppy that automatically has changed to Mac format. This floppy disk contains a StuffIt Expander 4.0.1 installer for Macintosh. Move the floppy to your PowerBook 180 and install StuffIt Expander.)
To hardware-connect:
- Make sure both PB180 and PC are turned off;
- Mini DIN-8M of (Mini DIN-8M to DB-25M) to PB180 modem connect;
- DB-25M of (Mini DIN-8M to DB-25M) to DB-25F of (DB-25F to DB-9F);
To software-connect:
- Turn on both computers;
- On PC, open Start->Accessaries->Communication->HyperTermical;
- Open File->New Connection, give a name such as ToMac, ok, leave all default except Flow Control set at None (no xOn/xff or Hardware Handshake) and speed at 57600, click Connect->Receive file;
- On PB180, all default except a) Settings->Connection (Data Rate to 57600 and Flow Control to no Xon/Xoff or Hardware Handshake checked);
- File->Transfer Convert (set to Binary);
- File->Send Zmodem (add up to 60 files and start transfer)!
- All files will be saved in C;\Documwnts and Settings\Owner on PC.
============================================================
Jan! 谢谢你！Danke! Je vous remercie! ありがとうございました！감사합니다! ¡Gracias!

Could you advise me on the following:
I have transferred all my photos from Mac to PC. Tiff files have no problems to be viewed on PC. Some photos are in PICT format, on the Mac side they can be opened by Pixel Paint, but on the PC side I tried several programs from the internet and none of them can open these PICT files.
Would you kindly recommend some programs that may open them?
Many thanks.

May 9, 2013 10:57 PMby Jan Hedlund,Hello Jim,
Sorry, cannot give you any advice based on experience regarding PICT on a Windows PC. If at all possible, I guess it would have to be in a program for viewing photos et cetera available on both platforms. For example, a quick look at file formats for a couple of Adobe products appears to indicate both some support and removed support for PICT, depending upon program/version.
One solution could be to try to re-save (Save As) to another file format in an already existing program on one of the older Macintosh computers. Alternatively, the same could perhaps be tested on the iMac (the shareware product GraphicConverter ought to be useful for this).

Also, you may want to have a look at Apple's QuickTime (for Windows), which seems to support PICT.
