This is a Diamond Trackstar 128 card from 1987. It's an Apple II on an ISA card, for use with PC-XT or Tandy 1000 computers.
Included are:

• Trackstar 128 card
• Manual
• Two copies of the copy-protected (rare) Utilities Diskette, versions 6.2.1 and 6.2.2.
• Small "F-keys" cardboard guide in (non-original?) envelope.
• Disk Adapter + cable
• RGB / Monochrome adapter cable
• Apple Unidisk Drive Adapter + cable

Original packaging is missing, as well as original composite video cable, but apart from that, this seems to be a complete kit, including the optional Unidisk adapter.
This was pulled working from a public school system computer and put into storage. It is UNTESTED, however.
Everything seems in pretty good shape with some small exceptions:

• Manual is slightly yellowing
• Disk label on 6.2.2 disk is yellowing
• Envelope for cardboard guide is in not-great shape. The guide itself is fine.
• Most metal surfaces, especially the brackets with connectors, have some slight discoloration / oxidation, that would probably clean up well
• Card bracket has its ports labeled in Sharpie

Please check the photos for details, and/or message me with further questions.
Again, this is UNTESTED but was working when it went into storage.
