 Re: Commodore plus 4 internal Roms

I would want a better version of basic, the version that should have been in the main roms.

One of those what-if's is whether commodore went the right direction after basic 2. The very early MS Basic offered a floating point interpreter that could run on a 4k altair 8080. But by the time of the c64/+4 they still used the same primitive system, only 2 char var name, slow search for vars and goto targets, no proper int arithmetic, etc.

In contrast, other systems (hp, atari 800, bbc, apple integer basic) took something closer to an "interpiler" approach. A full version of that would be tokenising/resolving long var/proceedure names, constants, etc, (even tokenising as each line is typed), offering better structured features, generating something close to pcode. That would have been the thing to fix before implementing those other gfx features in basic 3.5/7.

If this was done for the +4 roms, maybe they could use routines from the basic 3.5 roms for gfx, float library etc.

Some time back I did start writing a version of Basic that did this (just in C to start), but its unfinished (like so much stuff).

Maybe an alternate OS would be nice. I like the idea of a game, though, but I might soon want to replace it, as I might get bored of the current game. happy

 Re: Commodore plus 4 internal Roms

This topic is REALLY interesting! Which kind of ROMs can be used as an alternative to the ones with the awful factory provided programs? Is there anyone out there selling replacement ones? I'd rather have a good arcade, an rpg, or even an adventure than that boring stuff!

 Re: Commodore plus 4 internal Roms

I have a Plus4 at my mother's house but never use the Three-Plus-One ROM: I find it to be annoying and hard-to-use. Would it be easy to swap it out? If so, for what can I substitute it?

I can say that Logo works. I tried it briefly some time ago and, while I didn't test it thoroughly, it definitely starts up! happy

Hi there.

Well, absolutely yes, I guess. Do you know that a rare Commodore 264 model which has been unearthed some years ago, had Micro Illustrator as ROM tool instead of 3-plus-1? You can now download and test the .bin file of the former from its page.
