Disk images

Image conversion

The emulator uses raw images of the SSDD disks (204800 bytes), but most of the images online are in Teledisk (.TD0) or ImageDisk (.IMD) formats and must be convertes. ImageDisk is a DOS program that can do that. It can run with dosbox.

Prerequisites

Install dosbox (sudo apt install dosbox in Ubuntu).

Extract the ImageDisk 1.18 files from http://dunfield.classiccmp.org/img/index.htm

To convert TD0 files to IMD:

  • On the host run dosbox .
  • Inside dosbox run TD02IMD FILE.TD0 (use ALT-F12 in dosbox for full speed)

To convert IMD files to raw:

  • On the host run dosbox . (if needed)
  • Inside dosbox run IMDU FILE.IMD FILE.IMG /B (use ALT-F12 in dosbox for full speed)

You can use the .IMG file with izkaypro

Moving files in and out of the disk images

Prerequisites

Install cpmtools (sudo apt install cpmtools in Ubuntu). Use -f kpii for SSDD disks (204800 bytes). Use -f kpiv for DSDD disks (409600 bytes).

Extract files from the image

cpmcp -f kpii kayprodisk.img 0:*.* destination

Add file to a disk

cpmcp -f kpii test.img source/sbasic.com 0:
