Question, what you need is an Apple joystick? because I have some.

Pretty much! I also changed the joystick button code. Applesoft uses a PEEK
to check for button presses, BASICA uses the STRIG command. Everything else
is the same.

I'm using a Compaq Portable III (286). I forgot the card brand but I
vaguely recall it might also be Kraft. I'm programming in the BASICA
from
the correct Compaq-branded boot disk. I use the STICK command; not
PEEK/POKE.
I can test the same joystick against the Apple side tomorrow.
In a test program, I was only getting a range of about 5 to 195, vs.
0-255.
To "port" the code from Apple to IBM platform, I replaced the Applesoft
PDL(0) and PDL(1) commands with STICK.
The way my code works is, when I move the stick beyond a neutral range
(say, within 75 of either end), then it turns on the robot motors on
the
correct directions.
The logic is fine: works with the Apple joystick on the Laser 128, and
as I
said I'll test that again with the Kraft tomorrow on the Laser.
But when I tried it on the Compaq, only two of the directions work
correctly. It was something like left and forward; I forget exactly.
One
other direction turns on the wrong bits (1 and 4, same as its opposite
direction, rather than 2 and 3 which it should be), even though I'm a
million percent certain the code is right. Another direction works
(bits
2
and 4) if I move the stick to its extreme edge, but while en route it
turns
on bit 3 for a second. That makes no sense! That's why I think the
stick
might be funky or somehow misadjusted even if it does work on the Apple
side.
The BASICs are 100% compatible? You just had one change and it works on
the IBM?
