FreHD Hard Drive Emulator for the TRS-80 Computers
This is a relatively simple project to build. The original repositories had some mistakes that I aimed to clear up with my repository.
The BOM that includes the actual part locations and part counts is here
https://github.com/mudmin/AnotherMaker/blob/master/frehd/bom/REAL%20Part%20locations.txt
There is also a spreadsheet that has some of the locations wrong (depending on the PCB versions) but it does have proper part numbers that you can cross reference if you're confused. https://github.com/mudmin/AnotherMaker/tree/master/frehd/bom
I've included all the source files as well as my own build notes here. https://github.com/mudmin/AnotherMaker/tree/master/frehd
PCBWay Note:
It is important to modify this board with a jumper wire: Let the two pins (pin1 and pin3) of Q1 form a short circuit with a jumper, and then leave the hole of pin2 hole empty and do nothing.
