I doubt that the lack of control-characters has much to do with the
enhancement. The control-key switch goes into the KR3600 keyboard encoder. I
suspect it might be loose or defective, or, the cable from the keyboard might
be damaged. Possibly the keyboard mapping ROM (not part of the enhancement)
has become loose or defective.  First use a logic probe to determine if the
control-signal is making it to the KR3600... then look at the data coming out
of the KR3600 (eg. with an "A" and a control-"A"). If they differ, then the
next thing is the ROM...
