Hello Group,
I purchased my ][+ in Aug. '81 and used the shift-mod to upgrade
my system. I ran a wire from the appropriate point on the keyboard
PC board to the unused connector which goes down to the main board
and ran a wire under the main system board to the PB2 connection
of the game socket. No visible wires to get in the way and never
had a problem with graphics programs. While I never used Applewriter,
Applewriter II or Bank Street Writer, I did use Magic Window and
the horrible 40/70 graphics screen to (barely) see 70-column text.
I added AE's Z-80 Plus and AE ViewMaster-80 shortly thereafter and
still had no problems with the mod.
Sorry about being so vague about the exact points on the kbd
PCB, but it was a long time ago and since upgrading my sister's
][+ in '84, I never gave the mod another thought, especially not
a reversal. I have seen many other wires with test clips going from
under the keyboard to the game socket, and figured that my way was
a bit more work, but worth not seeing nor messing with the wire
was worth it. I can dig up my notes as to which kbd connector pin
is unused and the rest of it, if anybody is interested. Contact
me directly and I'll send e-mail of the details.
Just my two cents, take care,
-John
