Hi guyz,
thanks for the info on WAVES and VOLUMES! Btw, I agree on the fact that all credits for wave cons go to WIT. It was a real BREAKTHROUGH! Anyway,
I checked the $ff1d-messing-thing on my color TV. It looked much better on the monochrome screen (no bending etc.).
Hopefully, this reproduces the effect...
s SEI
LDA #$02
b1 CMP $ff1d
BNE b1
LDA #$04
STA $ff1d
LDA #$ff b2 CMP $ff1d
BNE b2
JMP s
There's some color flickering, though, mostly the screen is greyish tinted. I'm just curious what the BAR in the middle of the screen is and, why it's covering the TEXT WINDOW.
Does anyone know if there are any (significant) differences between the
1551's 6510T and the 6510 used in C64s, or the 8510 or what the later version was called?
Cheers,
CHICKEN
