IBM 6150 RT

The IBM RT (IBM 6150/6151/6152 ) was a Unix microcomputer of the first generation from IBM. RT stands for RISC Technology. It was the successor to the experimental IBM 801 and predecessor of the successful RS/6000-Serie of IBM. In 1986 he was first introduced as a RT PC, but eventually renamed to its final name because of name confusion as PC RT.

It was introduced at the CeBIT 1986 in the German market and was either in the Tower (IBM 6150 ) or desktop housing (IBM 6151 ) are available. He had a 32 -bit processor of the type ROMP with the basic equipment 5.88 MHz, which unfolded about the performance of the then-current 80286 at 12 MHz. There were also advanced processor card with 10 or 12 MHz and a Motorola 68881 floating point processor available. The RAM ranged from 4 MB in the basic equipment to 16 MB in the maximum configuration. The device used as AIX operating system ( to version 2.2.1), Academic Operating System ( AOS) or the Pick operating system. As an IBM 6152 an ordinary PS / 2 Model 60 with an additional processor card was later available that could load the AOS from a RT in the network.

How to later IBM Unix machines a two-digit seven-segment display was also attached to the IBM RT that has the POST code on startup, as the video adapter was not yet initialized at boot time to do there eg error outputs can. For system expansion served up to eight ISA expansion cards. For data backup could be used on a DC600 - ¼ -inch tape drive. The drive system consisted of up to three full-size 5 ¼ -inch ESDI hard disks of each 40 to 300 MB. The installation of the operating system was carried out by 5 ¼ -inch floppy (about 32 pieces in AIX). The system had up to two such drives with 1.2 MB capacity.

The IBM RT was often used as a CAD workstation in conjunction with a graphics terminal, Tektronix. CAD programs such as CATIA, AutoCAD V3 or DOGS2D could AIX deal with on the X Window System (version 9 or 10) driven graphic display terminal.
