vic screen border color

Were any vic set to boot up with orange border and white screen? I have one that displays like this, it is an early one #57,###. It works great otherwise and If I poke 36879,27 it displays cyan border with white screen. All games and demos work fine. This seems odd though since all my other vics have cyan and white screen.

Not that I knew about an official variant. Besides, the VIC chip can't display orange as border colour, more probably this is yellow.

And the value you can peek before is ...?

You can dump the kernal as follows and make it available here to judge whether there are other differences in the ROM, or just one bit has flipped:
Code: Select all
1 OPEN2,8,2,"KERNAL-DS.PRG,P,W"
2 PRINT#2,CHR$(0)CHR$(224);
3 FORT=57344TO65535:PRINT#2,CHR$(PEEK(T));:NEXT
4 CLOSE2

I will check out 36879, never thought of checking value at boot. I will post back, I need unpack it again. If it is different I will dump rom. thanks

As it turns out, I am more screwed up than the vic, hahha.. It was awhile since I checked that computer and actually the vic is green border with white screen. I checked location 36879 and it was indeed 27. I must have been doing some other things at the time also. So it appears that it is the video circuit or the vic. But, since it works great otherwise, I am just going to leave it for now as this one just sits in box mostly(it looks like new). Thanks for the suggestions, I will keep my info more current next time. (I could swear that thing was orange last time I looked).

I had a VIC that took time to warm up and the colors appeared to change after a few minutes (at least to me), but I never found out what colors they were.

Actually, I'm not sure I've ever heard of the color "cyan" outside of the VIC.

Most probably you find it with the CMYK (
cyan-magenta-yellow-key, key := black) colo
ur (;)) model for printers.

I thought the early IBM pc had it as well Cyan, magenta and white as color choices. CGA I think.

Just about all the early colour computers used cyan.
I think it was to get us used to detecting cyanide poisoning from bad capacitors.

Cyan is such a friendly color, like the computer. I think X has a color code of "SeaGreen" to describe cyan.
Of all C= models, I liked VIC20 and C16 default colors. I was never a fan of the boot up default C64 colors... perhaps a light blue border, light gray screen combo with blue characters would have given it the advanced distinction over VIC without the dramatic / traumatic transition.
