 The article from December 1984 BYTE, RAR compressed PDF




The article was provided by Paul Santa-Maria (on planet earth from June 8, 1962 - June 19th, 2010, RIP)

I've proofread this countless times.

listing1 creates hires lookup table
listing2 creates shift tables
listing3 is assembly language code
listing4 is divide by 7 tables
listing5 puts all of the tables together
listing6 is a demo to demonstrate the code

I finally got it to work.

make sure capslock is on, and use:
-I-
JKL

to move the arrow around.  press space bar to stop the arrow.


Read the above PDF, it is a very interesting method to shift things around on the screen.  The shape isn't preshifted, but there is a shift table that will shift ANY byte.
