Implementation on Olivetti L1


Hardware platform Olivetti L1
Operating system Unknown
Author Bob Eager
Implementation method C-map
ML/I version CJB
Implementation version 1.1


This was the first ML/I implementation which was performed using the C-map. The Olivetti L1 ran an emulation of UNIX 4.1BSD, and was unusual in that it had 16 bit integers and 32 bit pointers. Since ML/I used pointers and integers interchangeably in places, there were quite a few problems; however, these served to strengthen the eventual portability of the C-map.

The C-map was necessary because the L1's emulated UNIX had no accessible assembler program.
