Thanks a lot, folks!

And of course, thanks so much Al for bitsavers -- the DEC archives 
there, for me at least, have made this whole hobby possible!

I have an early (serial 152) 11/45 that I've been restoring.  Just now 
to the point in CPU debug where I can reliably toggle in and run simple 
programs.  Next step will be to get some serial I/O going so I can 
conveniently load some more thorough diagnostics and be sure the CPU and 
memory are completely shaken out.  Then on to working on storage.

I have a pretty complete set of CPU spares, but they are of various 
different revisions, having differing sets of green wires etc.  I'd like 
to have a look at the ECOs at some point so I can properly sort out and 
record what is what, and/or possibly bring all the boards up to a 
consistent level.

         cheers,
