All,

I apologize for not killing the spam previously. I changed some settings so it's more moderated.

Happy Apple_II gaming and programming!

uberregenbogen @ 01:28 pm: Stupid Applesoft trick of the day: Drawing a MouseText frame with lo-res commands.

Quickly drawing a MouseText frame by writing codepoints into into the lo-res graphics colour register and painting the lines with lo-res graphics commands.

(Writing directly to the colour register at $30—rather than using the COLOR= command—allows setting different colours for the top and bottom pixels of each byte, and, consequently, the painting of rows and columns of characters in text mode, with HLIN and VLIN.)

[Requires a MouseText equipped machine (IIc+, IIgs, IIc, Enhanced IIe), of course, lest it look like crap.]

1 TEXT : HOME : PRINT CHR$(17); : POKE 49167,0 : REM 40-col; MouseText
2 POKE 48,223 : HLIN 1,38 AT 1 : HLIN 1,38 AT 0
3 POKE 48,76 : HLIN 1,38 AT 47 : HLIN 1,38 AT 46
4 POKE 48,90 : VLIN 2,45 AT 0
5 POKE 48,95 : VLIN 2,45 AT 39
6 POKE 35,23 : POKE 34,1 : POKE 33,38 : POKE 32,1 : HOME : LIST : END

mookieghana @ 07:24 pm: Coloroid for Apple //e
My wife really enjoys playing COLOROID for her Android phone. I immediately thought it would be a fun thing to program for my Apple //e. I wrote this code this morning.



Input:
You can have the computer take guesses to solve the puzzle with "A".
"Q" quits the game.
1/2/3/4/5/6 = colors

Hope others enjoy! I need to speed up the algorithm - possibly by replacing some of the IF/THEN statements with conditional logic (turn "IF X>39 THEN X=39" with "X=(X>39)*39+(X<40)*X") I believe that speeds up execution.

You can download the file for an emulator (like APPLEWIN) here: http://sites.google.com/site/cdhapple2/coloroid

mookieghana @ 09:58 am: KOTB [apple-ii] video
There's a "King of the Board" tournament over at f4wonline - a mock election on a message board for a Wrestling/MMA fans. Yesterday, I decided to dust off the ol' Apple //e and write a little "simulator" on who might win...



I learned a lot about switching between 40/80 character width mode (i.e. PR#3). I used an old routine called "Curtain" to do the shuttle-launch at the end. I don't remember if I got that from a NIBBLE magazine or whether that was in one of my Apple ][ Sound+Graphics books.

It seems like my disk drives are starting to go funky. They would suddenly start producing a lot of PATH/IO errors. But I was able to move the drive and adjust the cords so it seemed to fix things. I'll post a video of the code if anyone really cares. It's been awhile since I tried a project like this, but I think it was worth it especially to celebrate my 25th year programming on an Apple //e!

whoracle @ 02:50 pm: VisiTerm issue cont.


The first selection (comm slot) doesn't change. Makes me wonder if there is some missing driver or something. The baud rate selection is a bit strange as well, doesn't let you actually select a speed, just 'low' or 'high.' Weird.

whoracle @ 07:13 pm: VisiTerm
Anyone have an old VisiTerm Manual Laying around? Can't get it to recognize my AppleSSC in Slot 2.

mookieghana @ 03:07 pm: NASCAR picks..

mookieghana @ 04:41 pm: Text on GR / HGR / HGR2
I am thinking about programming a clone of the NES game Palamedes for the Apple ][. I was thinking about making it ultra-lo-tech and use GR but I wanted to put numbers on the GR field. I've seen it done (thinking old Microprose games among others) but I don't have any idea what code to use. Suggestions?

whoracle @ 03:42 am: ][+ Encoder board
Anyone out there know where one might find a replacement keyboard encoder daughter board? Part 605-X105. My ][+ keyboard starts randomly typing endlessly without me touching it. Tried to reground it with a jumper wire to motherboard GND, but that didn't fix the issue. I could just get the Super Encoder from Briel, but I'd like to keep the ][+ somewhat original. Ideas? Fixes? Cheers.
