Oh and I just realized, you would have to load a BMP file as a .CO since 
it is raw binary data, and BASIC would have to access by manually 
finding it's address in the MENU directory, then use PEEKs to read the 
data since it is binary.

The DRAGON.BA file is 2098 bytes because it includes:

  - APRAW encoded ML strings
  - PRTSCR (print screen) encoded ML strings
  - BASIC code to load the above 2 ML programs to ALTLCD and LCD memory 
space

  - BASIC progress bar printing to show ML load status
  - BASIC code to validate the ML checksum
  - Keyboard input logic
  - DRAGON.DO encoded image strings

If I remove the printscreen code, keyboard scan logic and progress bar 
logic, the size reduces to 1488 bytes.

Re: [M100] Help with simple image on M100 screen?

[Ken Pettit]

Yes, it would be possible to write a "screendump" ML routine that 
converts to BMP, but it surely wouldn't fit into ALTLCD's 320 byte code 
space and would have to be a .CO file that is loaded somewhere in 
HIMEM.  A screendump could be useful for some applications I suppose.


Of course the BASIC programs we have been talking about are displaying 
an image on the M100 LCD that *originated* from a JPG / PBM file.  So 
why not just convert the JPG / PBM file to BMP directly using your fancy 
i5 or i7?  In fact, and this was purely for testing purposes mind you, 
;-)  I have *other* images I have created for the M100 that can be 
displayed using APRAW which came from JPGs (images you probably wouldn't 
want to display on your portable if you were, I don't know, at work for 
instance).


The idea of actually "printing" the screen to something (anything) like 
an FX80 just seemed retro-cool, and since the only compatible "printer" 
I have is the VirtualT FX80 emulation, that became the natural choice.

Re: [M100] Help with simple image on M100 screen?

[Ken Pettit]

All,

Note that the previous DRAGON.BA file has a bug if you actually try to 
print the image.  It doesn't re-enable interrupts after printing, thus 
forcing you to reset the M100 using the reset switch (the keyboard scan 
loop is disabled, so CTRL-BREAK doesn't work).


The attached updated DRAGON.BA fixes this.

Re: [M100] Help with simple image on M100 screen?

[Ken Pettit]

Funny this topic should come up today ... the past week I have been 
having fun trying to put together a holiday "greeting card" that 
displays some graphics and plays music.  I have the graphics routine 
done (a much simpler code base than asciipixels I call apraw for 
AsciiPixels RAW), but haven't gotten to the music part yet.


The code I have is a BASIC only implementation that loads a small ML 
program into ALTLCD and then draws a graphic from BASIC Strings.  It is 
not as advanced as asciipixels in the following ways:


   1.  Asciipixels can draw an image at any X,Y location.  Apraw can 
only draw at x*8, y*8 locations.
   2.  Asciipixels uses much better image compression than apraw and 
can use only 7-bit ASCII.  Apraw uses 128 bit ASCII (which can sometimes 
cause issues with TEXT I noticed).
   3.  Asciipixels supports "pointers" and image masks.  Apraw is just 
blasing bytes to the M100.
   4.  Asciipixels has both M100/M102 and T200 support.  Apraw currenly 
only supports M100/M102.


Attached is a screenshot of VirtualT running a sample BASIC program at 
2.4MHz emulation speed (i.e. actual speed of the M100).


Let's talk!  :)

Wondering if someone here could potentially help me with a silly /
pointless / fun little project. I have a sizable collection of
vintage computers and devices, and once in a while I like to post
one of them displaying my company logo to my team Slack channel.
Totally impractical, but it’s a fun way to blur the lines between
my work and my retrocomputing hobby.

Bearing in mind that I’m *not* a programmer, I’d like to find a
way to display a simple 1-bit image of my company logo on the
screen of my Model 100. Is there anyone here with the ability to
help cook up some BASIC code (or something comparable?) for doing
this? Given the borderline non-existent graphics capabilities of
this machine, I’m guessing it would involve some kind of
pixel-by-pixel bitmap or something, but as noted before, I’m no
programmer so I’m just guessing here.

Let me know if this sounds like the kind of gag you’d be able to
help with - there could be a dollar amount roughly equal to a
6-pack of your preferred drink in the mix… :-)

Not so bad as that... it has PRINT@, CLS, LINE, PSET/PRESET, PRINT@ along
with block graphics characters. So a fair amount of stuff. No circle
command.

It depends on what you want to do. Unless you want to code up your logo
with primitives, you probably want to convert your bitmap.

In which case Steve is right, I think Ken's ASCIIpixels allows you to embed
bitmaps in strings, probably the way to go. So it's just a matter of
converting your bitmap.

Maybe attach your bitmap and someone will convert it if you don't want all
the fun.

Sounds like a great use case for... asciipixels!!!
Although Ken might have to repeat his instructions.
