Thanks for your replies Paul and Jay.

I spent the last hour cobbling together a GitHub Repository for RSTS-E

It's at

I've included a context diff for the FIT patches I mentioned and an updated
FIT.TSK image built for RSTS/E V10.1 with BASIC-Plus V2.7 (and also the
Mentec RT-11 V5.7 release notes that discuss the time word changes), along
with an Ethernet patch that Paul posted about in 2016 to increase DECnet
performance under SIMH PDP11.

I also found the cover letter for the Mentec RSTS/E V10.1A Year 2000 Update
and included this.  Someone out there may be able to provide further

At some later stage I'll start collecting other RSTS/E software that I wrote
and upload it too.  It's silly to keep this hidden away only to be be lost
forever when I'm gone!
