I have more information.
I received the first ADA1200 that I ordered. It came with a software tape from CMC. There are 6 "programs" on the tape.
It was a real trial to recover them from the tape (the dipoles must be fading) there were file name errors & load errors. But I used an old trick, by bending the spring arm in the cassette which forces the tape against the head harder (this increases the signal levels) I was able to recover all of the programs, they are:
CONTENTS
BAUD RATE
PLOT PROGRAM
FORMAT NUMBERS
SCREEN DUMP
DELAY ROUTINE.
The idea of the delay routine is to delay the serial data after a carriage return, long enough to allow the printer head to return to its home. This program is executed using SYS commands where the cassette buffers are.
