I-Paint v1.5b came with a 1541 "flippy", unlike v1.3, which came on a 1571 disk.
Voyager Mindtools was known for its strong support for C128 hardware (like the 1571)
but may have bowed to customer complaints and switched to 1541-format disks.

Many of the files on the "flippy" are compressed. When uncompressed,
much more space is needed. Therefore, included here are a 1571 image with all of
the program files plus a 1541 image with the sample files.
Also included is a 1581 image with everything.
