Fred Gruenberger was a well known computer pioneer, author and professor at California State University, Northridge. He wrote 28 books on computing, and started the Computer Science degree program at Northridge in the early 1970's. In June 1973 he announced he was going to publish a monthly...

The amazing "Living Computer Museum" in Seattle Washington "temporarily" closed during the COVID epidemic, then said they are re-evaluating "if" they will reopen. But their Facebook, twitter, and website updates have been silent for a very long time. Does anyone know what's up? I suspect they...
