I am about to upgrade from a Commodore 128 to an IBM AT, and would like to be able to take all my word processing files with me. The hard part is transfering them from CBM format disks (GCR) to IBM disks (MFM). I know that there exist programs for the C-128 that will read/write IBM disks, but I would prefer the program to run on the IBM and read the CBM disks (the Commodore program runs SLOWLY). Does anyone know of a program that will perform this feat? ZB

The Amiga disk controller reads/writes entire tracks of data at a time. The MFM encoding/decoding is done in software on the Amiga, using the machine's bit-blit coprocessor to speed the process. Since most of the process is handled in software, the system can easily handle other formats. m. -- __ \/ Michael Portuesi Silicon Graphics, Inc. portuesi@sgi.com "Never forget what gossips men are, and how they love to feel superior to so-and-so who `is having trouble with his wife.'" --Nina Fischer, "How to Help Your Husband Get Ahead" part of the Amy Vanderbilt Success Program for Women

The standard floppy controllers in any 'good' computer can only read FM/MFM. Commodore's formats require special designs. I'm even amazed that one can acces MS-DOS (MFM) floppies in a Commodore drive/controller.

The hard part is About the easiest way to do this is to upload the files from a Commodore to some place and then download them to your IBM. Or, if you have them both available, tranfer the files by direct serial link. I'm not sure if that is so easy with Commodores. But you are sunk as far as trying to directly read the disks. Mark C.
