Month: December 2015

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.

I’ve added lessons on two relative branch operands that have become fundamental tools for “baseless” programs:  Branch Relative on Condition and Branch Relative on Condition Long.  You can try out these instructions in VisibleZ as well.  Upload the new Codes directory for some sample object code programs, or build your own.

Along with these lessons, I cleaned up some links on the assembler page and added links to all the lessons in three formats (PDF, DOCX, HTM).

I’m working on an assembler book that will organize and combine the information you can find on the site.  I hope to complete it over the next few months.  If you have special requests for topics you would like me to include, email me your suggestions.  I’d like to know the instructions you’re using that aren’t represented here.

It’s been a while since I updated the copy of VisibleZ on the server. Tonight I uploaded a fresh copy of it along with an updated Codes directory which contains more sample programs than before.
