Wow! I’m sad to say, good luck with this one. I’ve not seen any sign of it
having survived. As close as I can get is the binder I have for COS-310 v8.01,
but that is for the PDP-8.
I’ve always thought it would be interesting to check out DIBOL-11, so would be
interested if you have any luck.
Does anyone have the DIBOL-11 software, which was packaged for RT-11
as CTS-300, and for RSTS as CTS-500?
My immediate interest is for RT-11, though I have a DECdatasystem-570
that I believe was originally sold with CTS-500, so it would be really
nice to get that as well.

That would certainly do it, but it's the first time I've heard of it

The ones you have to watch out for as a rule are those made by Mostek. Not
sure of the date when they changed to recipe.
If your still in/near PDX I will be getting my Unisite+ back in March and I
may have a working Model 29 that you can borrow.

Well, why not power it up again and then no one has to guess "what has happened
since"?

use the arbitrary-precision and variable-format float machinery in the GCC
compiler (file real.c). It probably doesn't quite give you what you need --
conversion from one format to another -- but I imagine that adding
