Observation:

1) Errors increase rapidly as size of area read increase.

2) Misses appears to be somewhat corelated with system
activity. Total [activity?] was 1 [bip?] program and 2 music
programs. [Wast?] misses (last amount read) seemed to
occur when someone typed.

3) Parity errors may be same ones we have seen for several
days when programs seen in ampex [?] and not
a result of using TV. There were no parity errors
found by 167.

4) Error rate for size of rectangles read by edge follower
appears to be around the limit we can tolerate but
we can live with it if necessary. MICROSCAN users may
be unhappy when reading large frames. It appeared,
although I have no statistics, [like?] the misses were
fairly evenly distributed through the read instead of
banded together. I could test this if desired.

Readjusted format tape lights for Analex
printer to try to stop it from skipping pages.
It will not fail for me, but time will tell.
