It was understood that R.BLOCH intended to build a new engineering organization in a new location, i.e., BRIDGEPORT Conn. and that selected participants will have to move there and some will have to expatriate. As almost all participants did not intend to start from scratch their professional --and sometimes personal life, so there was a considerable reluctance to follow a person who never imposed himself as a charismatic leader.
Just after Shangri-La, Bull reorganized its engineering to be able to take a strong position in the incoming bargaining.
A commonalty with IBM S/360 I/O at channel- program software level was studied at that time to evaluate a S/360 emulation. The general specification of the PSI channel was specified and particularly its radial configuration as opposed to the multi-drop IBM channel.
Bull performed an analysis of a paging architecture in measuring the sensibility of the operation of IBM OS/MVT running under CP67 on the Grenoble university 360/67. It should be remembered that main memories were still extremely small and that it was requested to operate a full functionality operating system on 64KB, and there was even a proposal to run such an OS -- with paging, into a 4KB memory for the low-end "A" system !
