Folks,
a new version of PDP11GUI is online.
It fixes some errors, including "Error 103", which occured when running
MACRO11 without administrator privileges.
There were also problems under Win10.
Download from http://retrocmp.com/pdp-11/pdp11gui
Bug feedback is necessary!
Enjoy,
Joerg

Hi Guys
Ok our front panels are going into production.
Meeting went well. We finally worked out how they did the matte layer on
the front
It appears to be a transparent or translucent white. Its ink base with

The effect is like a steamed up window or shower glass panel.
