The CHM Restoration Committee, some CHM PDP-1/IBM 1620 Restoration
Team Members (including myself) have a G-15 in the "short list" in
their thinking regarding potential restorations. There's plenty of
software available for the G-15 - and the project is a lot less
demanding than the DEC PDP-1, IBM 1401 and IBM 1620 projects we have
or are tackling.
If we obtained an additional G-15 from another source, that would
certainly be a factor in making such a decision.
However, by necessity, the restoration selection process at the CHM is
complex - as it has to take into consideration everything from
exhibit plans, demo requirements, educational value, availability of
staff, team leadership, volunteers, etc...
