NatSemi 32000

Tektronix (the Oscilloscope people) built a line of early Unix workstations based on the National 16032 (which was the 16-bit bus version of the 32032). These machines were the Tektronx 6130 and the later Tektronix 4132. I have running examples of each. These machines ran a Tek-hacked version of 4.2bsd called UTek. The machines were essentially a single-board computer that had the CPU, some on-board RAM (1MB), a ST-506 hard disk interface (on the 6130) or SCSI-I Interface (on the 4132) a floppy controller (on the 6130), two serial ports, a GPIB port, an AUI connector for 10Mb Ethernet, and a bus interface that allowed various option boards (RAM, Async, Parallel, SCSI, GPIB) to be plugged in. These machines were actually pretty cool for their time...and if Tek would have marketed them properly, the could have competed with Sun's machines. But, Tek was an instrumentation company, and they really didn't know very well how to market a Unix workstation. Tek made another attempt at the market with the 43xx workstations, but these used Motorola 68K and 88K CPU's, and never really did very will with them.
