The new KL1091S in the ex-Nicole room
In January 1981, a limited configuration of the New KL1091S with a KL10E processor (36 bits) was installed provisionally in the ex-"Salle Nicole" laboratory. There are two tape drives and two RP06 (600 MB) diskpack drives, with the CPU and memory behind. The additional computing capacity was welcomed by the scientists, though the KI10 still provided the daily service.
The new machine room planned for ILL19
The new machine room planned for ILL19 had to be large enough for the biggest computer in the competitive tender. This was the ICL-2980, which had 16 disk packs each occupying about 0.8x0.8 m2. The final choice, a DEC VAX8600, included two RP20 winchester disks each with two spindles in a unit about 1.6x0.8 mm2 giving a total of 2 GB storage. Thus the room turned out to be largely oversized.

The KI1091S as installed in the new ILL19 computer room
After the move from ILL7 to ILL19 (July 1981) the system still awaited delivery of the big (2 GB) RP20 data disks and the two
additional tape units together with the networking (DN34) front ends. The room allocated to the DEC Service staff is on the
far left.
