Little is known about this system. Help welcomed !
I.S.T.C. (Informatic Systèmes TéléCom) was a french company which was selling imported computers from USA, like the [Apple II](/museum/apple-ii/) or the [Compucolor](/museum/isc-intelligent-systems-corp-compucolor-ii/). So it wouldn't be surprising if the ISTC 5000 was also an imported system. But which one ? We have not found the answer yet...
It is a big system with a built-in 10'' amber display (80 x 25 characters) and one or two integrated 5.25'' disk-drives (143 KB or 403 KB formated).
Following software was available : Basic (delivered with the system), Macro Assembler, Extended Basic, Fortran IV ANSI, CP/M, Cobol, Pascal...
A **5500** model was also released a bit later (1980), with slightly better features (disk drives capacity : 1 MB each)...
