Awhile back, someone in the list was talking about fast display routines
for the Model T.
I know the LCD is slow in displaying graphics, but I was wondering if
anyone could share some assembly language examples of fast display
writes. The Model T doesn't have a bitmap mode, and even if it did,
screen writes would still be slow.
I was watching this video by the 8-bit guy concerning his new "Attack of
the PETSCII Robots" game, where he explained redefining characters to
make the graphics for the PET, Vic-20 and C64.

I'm pretty sure you can't do that with the Model T unless you have a
REX, and maybe not even then.
Now, the Model T does have graphics characters, but to move a "sprite"
on the screen smoothly would involve, I believe, a lot of calculation as
to what graphics characters to use and when.
I've limited my game ambitions thus far to text or strategy (Oregon
Trail rewritten to "Organ Trail"; a port of a C64 Master of Orion type
game, "Reach for the Stars", which used * for stars). Still working on
both).
But that game of his makes me want to do more graphical games without
substituting ascii characters a la rogue.
Even a 4 character sprite rather than the 9 characters he uses would be
good if it could be written fast enough.
Being able to create a condense font as view80 does would also be very
handy.
So I'm hoping someone out there has learned some tricks for quick graphics?
I'm reading the Hidden Powers book, but am still scratching my head a
bit about writing to the display.
Thanks for any info or advice.
