General Discussion - Introductions / Re: Why did you choose the CPC...

Last post by Bryce - Yesterday at 18:22

The company where my father worked had a offer that employees could buy a computer at a discount. As far as I can remember, the C64, MSX, Enterprise, C64 and Atari 800XL were the options. My father chose the CPC as we only had one TV and my father (wisely) thought, that if the computer didn't come with a monitor, conflicts may arise. Unfortunately, he wasn't convinced that I needed a computer at all, so he went for the cheapest model: CPC464 with a GT65*.

* Yes, it really came with a GT65 although it was a 464.

"Note that bit 14 of the PAL selection address must be at 1 on CPCs equipped with CRTCs 0, 1,
2. It can be at 0 or 1 on CRTCs 3 and 4. For compatibility reasons, it is strongly advised to always
set bit 14 to 1 to select PAL."

I recently discovered a trick
LD BC,#BC0F
OUT (C),C
LD A,#C7
LD BC,#3DFF
OUT (C),A.  <=== Set PAL and remembering settings in CRTC Cursor address register.

In CRTC3,4 its not work?

Not compatible.
In Basic on CRTC 3, 4...
OUT &7F00,&C7
POKE &4000,&C7
OUT &7F00,&C0
POKE &4000,&C0
OUT &BC00,&F
OUT &3DFF,&C7
PRINT HEX$(PEEK(&4000))

Why not an ebook instead of a pdf? I'd back it then...😐

Because that requires extra formatting and effort, and it doesn't work with such an image-heavy book.

Programming / Identifying firmware version

Last post by abalore - Yesterday at 16:05

Since lower ROM doesn't have a header, does anyone know a way to identify the installed firmware (464 spanish, 664 , 6128 danish, etc) ?

The only way I can think for now is to have a table with all checksums, but it's a quite big task.
