Thread: 22DISK will not read Osborne 1 disks

  1. #1

    Default 22DISK will not read Osborne 1 disks

    I recently made some disks using ImageDisk for my Osborne 1. It has the floppy drive upgrade with two double density drives. The disks booted and was read fine on the Osborne 1 (I had to change the transfer rate from 250kpbs to 300kbps in ImageDisk though). Now I wanted to copy some files to the disks using 22DISK from my 486 DOS machine (which has a 5.25" floppy drive that supports both DD and HD disks) but no matter which disk format I set it to (SSSD, or SSDD for Osborne 1), it won't be able to recognize the disks.

    Am I out of luck?

    Did you purchase a registered copy of 22Disk? It has about 550 different definitions of which 11 are for Osborne.

    I've thought about it, and I've decided to quit registering new 22Disk customers. When a floppy disk drive is a rarity on a computer system and most young people wouldn't know what to do when a floppy was handed to them, it's time to retire the product. Of course, I'll still respond to registered users requesting support for an unknown format, as I've done for the last 33 years.

    I'm not going to release it into the public domain. That just wouldn't be fair to the people who actually paid for it.

    Thanks Chuck for the reply. I am using the unregistered version which has 9 formats for the Osbornes, out of which, two are for Osborne 1. I'm not sure if this is a software limit by the unregistered version or my hardware limit.

    Give Larry Kramer's Linux utility a try. I suspect that the definitions are based on 22Disk.

    If you want, upload an image of your problem disk to a file-sharing site and PM me the link. I can tell you if it's you or 22Disk that's the problem.

    I downloaded the disk images from Dave's Old Computers: http://www.classiccmp.org/dunfield/i...d/osborne1.zip
    There are quite a few images in this archive, and I cannot read pretty much any disk created from them on my DOS machine, for example, OS1SYSD.imd. They all booted fine on my Osborne 1. Any info is much appreciated!

    How is your 'tweener set up? i.e. OS, drives? I assume that your DISKETTE.CFG file represents your setup?

    Itís a 486 with DOS 6.22 installed. It has an EPSON SD680L655 floppy drive which I had no problem making disks for the Osborne 1. As far as the CFG file, where am I supposed to see it? I canít find it in the 22DSK directory.

    Run the program VIEWCONF and see what it says. (Should be part of the 22disk distro, but since I didn't make the one you're using, who knows?)

    Just tried it on a couple of the files. Worked fine. Tweener was a AMD K6-2 500 with 1.44/1.2 drives. MSDOS 7.1 (Win98SE).

    Here's a sample:
    Code:
    CDIR Ver. 1.44-Sep 14 1997, Copyright 1996, Sydex.  All rights reserved.
    Osborne 1 - SSSD 48 tpi 5.25" format
    
    B0:AUTOST.COM      B0:COPY.COM        B0:HELP.COM        B0:MOVCPM.COM      
    B0:PIP.COM         B0:SETUP.COM       B0:STAT.COM        B0:SYSGEN.COM      
    B0:XDIR.COM        
    
    28K free on drive B:
    The above files as copied to DOS.

    Code:
     Volume in drive D is DRIVE_D_   
     Volume Serial Number is 180E-1BF4
     Directory of D:\ALIEN\ostemp
    
    .              <DIR>        08-11-20  1:34p .
    ..             <DIR>        08-11-20  1:34p ..
    AUTOST   CPM         2,432  08-11-20  1:35p AUTOST.CPM
    HELP     CPM        17,920  08-11-20  1:35p HELP.CPM

    XDIR     CPM         2,304  08-11-20  1:35p XDIR.CPM
             9 file(s)         53,376 bytes
             2 dir(s)        8,898.51 MB free
    When using 1.2M drives for this stuff, you have to set IMD to double-step and 250Kbps->300kbps in the menu. 22Disk sees the 1.2M (80 cylinder) drive and assumes double-stepping for a 48 track original.

    I tested the shareware version of 22disk with OS1SYSD.imd and it worked fine. What's the cost of 22disk? Would you sell one last copy for old time sake?
