Is there a PD or Commercial software for reading/writing 720K MSDOS disks on a MAC+ 800K drive? ******************************************************************** * "I believe in a God which doesn't need heavy financing.", Fletch * * Ramanjeet Singh Anand * * CIS: 73767,2161 VANCOUVER * * USENET: a72@mindlink.uucp BEAUTIFUL BRITISH COLUMBIA * ********************************************************************

NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO NO You need HARDWARE. See the article in the current MacUser. It gives all the information and some test results. Below you find a summary of responses when I asked the same question a few months ago. For the Mac Plus owner only options 1,2,5,6,8 and 9 work. MacUser recommended Kennect and the superdrive. ************************************************************************** * If you don't have a hard disk or need an extra removable one, and if * * you have patience and guts, you might want to wait for the FLOPTICAL * * drive. It stores more than 20MB on special floppies, accesses them * * like a slow hard disk AND reads and writes 720KB and 1.44MB MS-DOS * * format. As far as I know not available right now in retail. See * * recent articles in this news group. * ************************************************************************** There are several drive solutions for the Mac: 1. Ordinary external Apple drive, connected via the Rapport (cable+electronics) from Kennect Technologies. Rapport costs about $220. (if you connect Rapport to the drive port of your Mac, the *internal* drive is pestered to *read* MS-DOS floppies, but it can not write this format) 2. Kennect 2.4 Drive together with Rapport (see above) lets you read/write normal and HD MS-DOS floppies, HD Mac and 2.4Mb format exclusive to this drive. Costs about $550 (together). 3. Apple 5 1/4" external drive. Needs an extra card, so not possible in the Plus. Gives only 360K MS-DOS format. 4. New Apple 3 1/4" external drive. Works like the superdrive, so you can read and write 800K Mac, 720K DOS and 1.44M DOS formats. I am not sure whether you can *format* all these types. Some people say the hardware is not that good. Expensive. Does not work with a Plus. 5. The PLI TurboFloppy is a SCSI device that can be added to any Mac with a SCSI port, and it is very similar in function to a SuperDrive (though it is not quite the same). It can only read/write 1.44Mb MS-DOS format. Costs about $350. 6. DaynaFile makes drives that read IBM disks, and from what I hear the interface is better than using a SuperDrive. The disks come up in the finder just like a mac disk. Old and expensive. I know of one solution for the **PC**. 7. Put a half card into the PC and connect an ordinary external Apple drive. Your PC can then read and write 800K Mac format. See an ad in a recent issue of Byte. A cheap solution. Other solutions are: 8. A modem, a network, and typing :-). 9. A 0-modem (RS232 cable between Mac and PC) or other direct connection (MacLink?). Don't discard this possiblity if you don't have a PC around. I guess you can get old IBM's (you know, the ones with the ssllllowww screen) or other machines real cheap and if the drive is in good condition, that's all you need. Might be cheaper than all these high-tech solutions above. With thanks to Darik Datta, keith@ux.acss.umn.edu, att.att.com!cbnewsc!fjo, Ingemar Ragnemalm, Mark H. Anbinder, Matthew T.

No. The Mac Plus uses a different bit-encoding method (GCR) than MS-DOS floppies (MFM). Apple's FDHD drive (available as an upgrade for older Mac SE and Mac II computers, standard on all Macs currently sold except the Plus) reads and writes GCR and MFM, so it can use software such as Apple File Exchange or Dayna's DosMounter to read and write MS-DOS floppies. You can buy external add-on drives which work with the Mac Plus; Dayna and Kennect (among others) sell such drives. --Brian Bechtel blob@apple.com "My opinion, not Apple's"
