I've recently run across some "MBR Products Inc." systems, which appear to be controllers used in structural (like building materials) testing systems, and included an MTS 442 and MTS 438 (436?) "Controller" in one of the racks with the MBR units. As far as I can tell, the MBR machines are S-100 bus based rackmount machines, with a built-in keyboard and video display, and an 8" floppy drive connected to some of them. There's also some other smaller MBR systems with no drive attached, but they didn't easily come apart for me to see inside them : ). Does anyone know anything more about these things? They look like they might just be a generic S-100 bus system with some special peripheral I/O for data capture/controlling. The processor board is a CompuPro board with a Z80B on it, for instance.
