I've been making these since 2013, with hundreds of happy buyers worldwide.

When ordering, please tell me which operating system you want to use so I can supply the correct boot floppy disk (see below for which DOS you need to just ask me if you need help deciding).

FreHD (pronounced Fred, the "H" is silent) - hard drive emulator for the TRS-80 Model III/4/4P/4D, this great little device emulates a TRS-80 hard drive, and uses an SD card for storage. Also has a real-time-clock, and utilities to transfer software easily from PC TRS-80 emulators to real TRS-80s.

You get:

FreHD board completely built and tested

1Gb SD Card with choice of operating system:

- Model 4/4P/4D: LS-DOS 6.3.1, LS-DOS 6.3.1 for High-Resolution systems, or CP/M 2.2

- Model III: LDOS 5.3.1 or NewDOS/80 V2.5

5.25" boot floppydisk for whicheverDOS you chose above

50-way hard drive cable

CD with technical data and other hard drive images

To use it just plug FreHD into the TRS-80 and a source of 5VDC power, and boot the TRS-80 with the supplied 5.25" boot disk. It's really that simple!
