More informations about this 1972 T1600 computer (and about its successor, the Solar 16.65):

• See the T1600 full configuration (1972-1980).



• The T1600 central processor unit (with a one micro-second cycle time) and the input-output controllers.



• The T1600 central memory: 32 KB (no, it's neither a joke nor an error!).



• See the contents and the dynamics of the T1600 central memory by means of a 256x256 black and white home made digital video system.



• The two T1600 disk units: 2x512 KB (!) to be compared with the size of the following JPEG picture -505.369 bytes- .




• The T1600 main man-machine interface (!).



And all this inside a 4-cubic meter volume cabinet! An air-conditioned room was mandatory!



• Six T4010 Tektronix display terminals were connected to the T1600.

Here are most of the programs written for the T1600 and Solar 16.65 computers:

• The CMS5 operating system.
• The CMS5 operating system generator.
• Some of the basic tools.
• Some of the SMC (Système multimédia Conversationnel) programs.
