Texas Instruments has Inc come out with four entry-level systems to fill out the bottom end of its System 1000 series of Unix-based multi-user systems. The new systems are based on the 80286 processor and fall bel-ow the recently announced 80386-based Series 1300 and the 68020-based 1500. Like other 1000 models the 1005, 1010, 1005M and 1010M use Texas Instrument’s implementation of Unix System V and they can all be upgraded to the 80286-based 1100. The Austin, Texas firm says that although its existing System 1100 can serve as a small system it would not be as cost effective to force it downwards instead of introducing the low- end models. Each of the four low- end systems have 1.5Mb RAM, 1.2Mb floppy disk, 60Mb tape backup drive, one parallel port and one serial port. The model 1005 has a 48Mb hard disk drive and a TI927 terminal, costing $7,195. The mod el 1005M has the same features as the 1005 but also has a multiplexer and costs $8,495. The model 1010 includes an 87Mb hard disk drive, a 924 terminal and costs $8,595. The 1010M is a 1010 with multiplexer and is priced at $9,895. As the additional 1000 models come out Texas Instruments is also cutting the prices of the original 1100 series by from $1,000 to $1,500.
