RSX-11M-PLUS Highlights

The primary change between V4.5 and V4.6 of RSX-11M+ and V4.7 and V4.8 of RSX-11M relates
to the KDJ11-E and to the provision of support for the TOY clock hardware on the KDJ11-E
beyond 2000. Upgraded TOY firmware was made available from DIGITAL in early 1999, the
O/Ss were modified to support that firmware.

In addition to the above changes have been made to utilities, which allow the software to
extend beyond some of the next failure points (i.e. a number of utilities have limitation
which will cause them to fail after 2027, some are limited to 2099). Most date limitations
in V4.5 of RSX-11M+ are for 2027 - changes in V4.6 will take most utilities to approx.
2155.

A new option will allow the system to display the year in four digit format rather than
the traditional 2-digit format that has been displayed in the past.

A number of cosmetic display issues have been corrected which caused some utilities to
display 2000 as 100. These are primarily in the layered products and have been corrected
in the update for V4.5 for the layered products.
