I'm always on the lookout for BASIC interpreters/compilers for various systems. I don't know if that BASIC ROM is actually a version of BASIC, though, without the manual or QRG for it.

Most of the 3rd-party ROMs do not have any documentation; the vast majority come from users that have found or purchased 41's with modules inside, and either donated them to folks that know how (or got procedures on how to do it themselves) and they extracted the ROM images.

Monte has been collecting them to add to the 41CL Flash library and has become somewhat of a clearing house of the latest versions. Note that the 41CL uses modules in the *.rom format, while the 41X uses modules in the *.mod file format. For simple, 4K, 1-bank modules, a .rom file can be easily converted to a .mod file, but for complex, multi-page modules you need to use more sophisticated tools like the excellent MLDL2K tools.

But if you need some of those, ask here first as there's a good chance someone has already built that first.

All that said, TOS and here in these forums are the best places to look for documentation for these 3rd-party modules, but if you still can't find it after looking, I'd suggest creating a new thread specific to that module here in the "Not Quite..."

Also, look at Matthias' amazing 41 ROM Module database: Not all of these are available from public resources, but if you find one you really want to check out, you could post a request here as well:
