Some colleagues and I recently published an academic article about VisibleZ in a Bulgarian computing journal. If the journal releases the article, I will post it on the site. For the record, here are the details:
David Woolbright, Vladimir Zanev, Neal Rogers, “VisibleZ: A Mainframe Architecture Emulator for Computing Education”, Serdica Journal of Computing-Volume 8, No 4, 2015.
I’m still cleaning things up and repairing some broken links on the assembler site as well as my academic site. I’ve about got them under control again after my sites went through a major server move at school.
