VAX Floating Point Formats

[Stephen Scalpone]

Since the  introduction of the VAX, two floating-point
formats have been added, the "G" and "H" formats.  Can
someone explain to me when these types were introduced
and on which processors?  Thanks.

Specifically, my old VAX 11/780 Architecture Handbook from
1977-78 lists two floating-point types, floating and double
floating.  The newer VAX-11 Architecture Reference Manual,
Revision 6.1, May 20, 1982, lists these two types as "F" and
"D" format.  The two new types, "G" and "H" formats, are also
given.
