  Update - MITS Altair 680b by Bill Degnan - 05/02/2007 23:01
I spent a number of hours working on this system. I reviewed the documentation, tested the memory, and I picked up a ACIA monitor ROM from a kind member of the Altair Computer Club. http://groups.yahoo.com/group/altaircomputerclub/

All seemed to be working, but I was unable to send output through the RS232 port to a display/monitor. I brought the system to the Trenton Computer Festival to meet with other members of my computer club, the Mid Atlantic Retro Computing Hobbyists (http://www.midatlanticretro.org)

Dan Roganti, Brian Applegate, and Brian Pope helped locate and fix a wiring problem (wrong pin connection in the RS232 connector) and now the system communicates with a terminal, displaying the dot prompt.
