I stumbled across a FreHD on ebay. This is a bare bones board. You get the board, 50 pin cable for connecting to the TRS-80, and the SD card. No you don't get 32G of storage. You get plenty for the TRS-80 as this is a 40+ year old computer.
It is a TRS-80 hard drive emulator. It uses an SD card as storage and will emulate a hard drive and give you a Real Time Clock. It comes with all the software for you to use it. On the TRS-80 you get software to read from the main directory as a way to transfer TRS-80 programs from disk images which are prevalent under Windows.
Invented by Frédéric Vecoven in Belgium, the FreHD hard drive emulator enhances your TRS-80 with fast, unlimited, inexpensive storage on SD cards. For insight into the design process of the fantastic FreHD, check out the inventors web site!
Since I have a TRS-80 4P the rom has the ability to boot from a hard disk. This is as far as the TRS-80 is concerned a real hard drive. So I ordered one on ebay.
I have a 3D printer so I have designed a simple case for it in Fusion 360. I also bought a 2A 5VDC power supply. A matching connecter, and a Push button switch with a blue led in it.
