This computer (~1975) is a product of Four-Phase Systems, Inc. whose products were distributed by Philips. Four-Phase was acquired by Motorola in 1983. The relationship with Philips continued for many years. The organization within Philips responsible for the Motorola products was included in the big 1 billion dollar sale to Digital. The organization continued its role within Digital, and now (anno 2000) Compaq.
The X1160 has the following characteristics:

• Four-Phase 7001 CPU built from MOS/LSI integrated circuits.
• 24 kBytes of word-addressable memory (a word consisting of 3 bytes)
• instruction cycle time 16 microsec typical
• 8 I/O channels for 64 devices each, net throughput 39000 bytes/sec
• built-in bootstrap
• supports max 32 CRT terminals
• two 2.5 Mbytes disk cartridges similar to IBM 2315 but with 2200 bpi density
• power consumption 500 W

Our machine seems to be fairly complete. However we have neither software nor documentation.
