I’m actually 69 and I went to C_MU with Clem a number of years back.  I’m trying to understand more about emulation of hardware and software
but have run into a few stumbling blocks with Open-Simh (PDP-11 portion).  I’m hoping to get the PDP-11 code running by the end of the year,
since I fear maintenance of the repository has not been kept up to date with current OS and development software distributions.
