PC99 Disk Conversion Service
Updated 980813

Your PC99 documentation includes full instructions on how to convert your TI 5.25" disks to PC99 format. If you no longer have access to a TI system, or simply don't want to spend the time to convert your disks, you can request CaDD to do this for you. To use the disk conversion service, you must:

  1. Mail the TI disks you want converted to the address on the CaDD home page. The TI disks should be in good condition and be either SSSD, DSSD, or DSDD. If the diskettes are flippies, see the table below. Warning: CaDD cannot guarantee to convert copy-protected diskettes.

  2. Supply sufficient PC disks for the converted files: For every four TI SSSD or DSSD, or every two TI DSDD disks you want converted, you must supply one formatted 3.5" 1.44Mb PC disk. The PC disks must be genuine high-density disks. Warning: Modified low-density disks cannot accepted and will be returned as is. If you want CaDD to supply the PC disks, see below.

  3. Optionally provide a list showing your TI disk name and the DOS filename that you want this disk to be called. If no list is supplied, then CaDD will select the filenames. For example:

    TI diskname DOS filename
    TURBO turbo.dsk
    ASGAMES-2 agames.dsk

    Note: DOS filenames must adhere to the 8.3 convention.

  4. Supply a return address label, and sufficient postage for the return of the disks. The disks will be returned in the package you provide.

PC99 disk conversion pricing

Conversion Type Factor You supply PC disks CaDD supplies PC disks
TI SSSD disks 4 $1.00 $2.00
TI DSSD disks 4 $2.00 $3.00
TI DSDD disks 2 $2.00 $3.00
TI SSSD flippies 4 $4.00 $5.00

To calculate cost, divide the number of each "type" by "factor", round up, and multiply by the dollar value based on who supplies the disks.

Example: You provide 6 SSSD, 4 DSDD diskettes, and 5 flippies, and want CaDD to supply the disks.
6 SSSD / 4 = 2. 2 * $2.00 = $ 4.00
4 DSDD / 2 = 2. 2 * $3.00 = $ 6.00
5 flippies / 4 = 2. 2 * $5.00 = $10.00
Total = $20.00
