- does anyone out here have a lot of knowledge in interrupts, DLI's, etc?
- I've already asked Jeff Potter about it (I just sent the mesg, so of
- course I haven't gotten a reply yet! :) ) and about sending me the
- sourcecode to interlaced APAC mode.. what I'm getting at is a 640 x 192
- mode using 16k (14-15 actually) of 320 x 192 (graphics 8) screen and
- flipping between the two... a breif example of how it works is this:
-
- say you had an 8x8 character bitmap:
-
- 12345678
- 1 ******
- 2********
- 3********
- 4*** ***
- 5** **
- 6********
- 7 ******
- 8
-
- you would first display this (this is NOT using the multi-flipping that
- Ilc'd APAC & colrview use):
- 1234
- 1 ***
- 2****
- 3****
- 4** *
- 5* *
- 6****
- 7 ***
- 8
-
- then you'd display this:
- 1234
- 1***
- 2****
- 3****
- 4* **
- 5* *
- 6****
- 7***
- 8
-
- together you'd get something like this:
- (assume the background is black and the foreground is light...
- the "*" would be lightest, the "+" would be medium, and the " " would be
- darkest)
-
- 1234
- 1+**+
- 2****
- 3****
- 4*++*
- 5* *
- 6****
- 7+**+
- 8
-
- get it? anyone interested in such a mode? it would even work with
- normal graphics 0 screens, not allowing for 80 column text (with 8x8,
- like this does) but for 40 column text, with a rounder feel (16x8x2, sort
- of a 8x8x4!)
-
- and finally, it could even bump up the 4 color 160 x 192 (x96) modes to 4
- color 320 x 192 (x96)...
-
-
-
-
- and of course, nobody forget my original idea for a low-memory 80 column
- text screen!!... flipping two screens, one with the left (even column
- #'d) characters, the other with the right (odd column #'d)... it'd use
- either a "left" & "right" character set pair, or with the scroll
- registers and a "left" character set...
-
- then if you wanted to display "Hi there!", you'd first show:
- "H hr!" and then
- "itee " ...
-
- c'mon... I don't know how to make this stuff! anybody up to it!?
