      Great work on this page. I like have an overview of S-100 IO chip usage with images and pdf links. Please add the Altair Turnkey Module to the list of boards with a Motorola 6850.

      You are correct, the Bitstreamer II is not used by Altair software. A Bitstreamer II and 2SIO can exist is the came system with standard board addressing. I have the BIOS source for a Tarbell 1011D and M6850 IO and Tarbell with a Vector Graphic monitor. I also have the source code for VG serial monitors. I also have MDM 7.12 for the Bitstreamer.

      The Bitstreamer can be useful for CP/M or if you are not running MITS softare. The monitor code may be useful until source code for a better 6850 monitor is found.  The Bitstreamer is not useful for Altair BASIC or DOS.
