This is an historical curiosity that I've uploaded to Github for archival and amusement value (for me, at any rate).
I wrote this code in the late 1990s to interface to one of Matrix Orbital's very first serial port LCD panels.
At the time, the BeBox was still the new hotness, and it had two real time CPU bar displas on its front panel, and everyone with a regular PC wanted something like that too.
The Matrix Orbital panel connected to a serial port, had 2 lines of display, and there were a couple of versions that could mount in a standard PC drive bay.
There's a driver program which builds as a Windows NT service, and it can load new screens at startup time through a DLL plugin interface.
