That’s odd. I can see one when I go there. Maybe there’s a region restriction?

But it doesn’t use VDC, right? How does the VDC RAM size matter? Do you remember where you got that information?

I’m not suse how much space JiffyDOS takes up. It consumes the space for cassette driver code since that’s removed.
Commodore did make a Swedish kernal so they did invest in it. The caps lock key turns on or off the åäö characters and rearranges the keyboard layout.

The C64 exists in a Swedish version. I do have ÅÄÖ on my C128 DCR keyboard but I seem to have an english kernal for some reason. If you want programs in your native language it matters of course. Some people can’t even type their names on an English C64 or C128. That’s a pity.

I’ve also just been poking around in this space recently when trying to see if it was possible to make a Swedish JiffyDOS ROM. It turned out to be hard because the new key tables takes more space and so does JiffyDOS. Both of them won’t fit and I gave up after a lot of thinking about how to represent the tables in a more compact way that’s still compatible with making custom ones.

Bjonte: The initialization begings with this.. hex = 'b bin = 'a then continues with the following.. err = -1 timeout = -2 baddata = -3 cerr = -4 spedl = -5 my assembler cannot handle negative numbers, but I _think_ i should make it err = 256-1 timeout = 256-2 and so on... I appreciate the responses! Yes, you are correct. Just add 256 to negative numbers as long as they are used as 8-bit numbers. Otherwise add 65536. In this case it seems to be a byte that represents an error state so 256 is most likely correct.

Still, to determine the original assembler used to assemble the source we need to see more code. Labels and assembler directives, like org or section declarations for example. The syntax will provide hints.

In order to recognize the source format you need to post some more code. What does labels look like and assembler directives?

What assembler is supposed to be used to compile the source code?
