Subject: MDM730 Overlay for Ithaca Intersystems VIO board with 2661 USART

Help:

I have an Ithaca Intersystems 525 (or 800) system with a VIO board that
has a 2661 USART on it.  The system is 3 years old.  The M7VIO-1.ASM
overlay for MDM730 is for the 2651 and, needless to say, doesn't work.
The initialization is wrong (comes up 300 baud, not 1200, etc.) and
when this is circumvented via a built-in terminal mode, every 10th-50th
character is duplicated in MDM730 terminal mode.

Solutions sought in order of desire:  (1) someone who has brought up 
modem7 on an II 525/800 and can help this lost soul, (->3) information
on the care, feeding, initialization, and I/O on the 2661, (<-2) another
M7 overlay, and finally (4) kind thoughts for one who will never enjoy
the pleasures of MDM730.

Thanks for all.  Tom.
