Here are some bugs I have fixed for RSX-11M-PLUS V4.5...

DSP3P1.SLP

When the error summary is given at the end of an error report, the
first and last packet numbers for errors are not correct.  This patch
will fix that.

DSP4P1.SLP

RPT crashes when processing a bad block replacement entry in the error
log.  This error were introduced in M+ V4.5.  I've checked the V4.4
sources, and it is correct there.  The problem is in
[104,10]DSP4P1.CNF. In this directory you'll find a DSP4P1.SLP, which
you can use SLP with, to patch the file to fix the problem.  Look in
the error logging manuals for how to compile and insert the corrected
module.

NEWXE.ENC

The XE: driver had a small bug, which nobody ever will be likely to
stumble upon, and a limitation, which I did stumble on, and it
generates error log entries, which noone handled.  NEWXE.ENC is an
encoded file. The utility to decode it can be found in the "misc"
directory on this machine. Inside is a univeral library holding four
files. Two .SLP files, to patch the error logging modules in [104,4]
to add support for the XE: driver.  One .SLP file to patch
[11,10]XEDRV.MAC, and finally a new error module, to be added to
[1,6]ERRLOG.ULB, namely EUNA.CNF.
