The TEP FTI990 is a rack-mounted system, consisting of several eurocards. Manufactured by TEP Elektronik Betriebs GmbH in Hambrug Germany in 1980. It consists of a CPU card (FTI990-CPU 1V/E) with a Texas Instruments TMS9900 CPU, two CRU cards (serial and parallel I/O, using a TMS9901 and a TMS9902), a digital 16-channel input card, a disigtal 16-channel output card, a memory card with 64 KB RAM (of which 56 KB is used) and 16 KB EPROM (of which 4 KB is used), and a floppy disk controller with two 5-1/4" DS/DD floppy drives (Philips X3114)

The EPROMs contain a bootloader for Eyring's PDOS (a multitasking disk operating system). After some repairs, the system is in working order, and runs PDOS. Eyring was a research institute in Provo, Utah, liaised with the Brigham Young University. It was this institute that spun off companies like Novell and WordPerfect.
