Adjusted -18V to -20V in LPT
This fixes marginal memory.

7/25 Core 3 / Look ahead bug

Back with a vengeance. Goes
N. AW. REQ. every few lines.
Came on very suddenly. Now appears
only in reading side lines (2 full screen),
leaves microscan alone in small - block mode.

Sometimes encounter parities in
unhanging core 3. My fault.
Pulled LA out by roots.
(LA active removed @ T8T)

Left leg of TTY2 is falling
off again. Bill Wichman & I suggest replacing
the losing Tinnerman nuts with honest
nuts & lockwashers.
