The Bitstreamer II works atb 6MHz with 9551 IO chips. The Bitstreamer II has software available for the MDM 7.12 modem program and Tarbell 1011D controller CP/M. The Bitstreamer II can exist in an Altair with minimum port address conflict. The Bitstreamer II works with the VG Z-80, PR-III, and ZCB.
