Doh, after thinking a bit, I checked my own Dennis Jarvis page: Dennis Jarvis Page | | | | Dennis Jarvis Page | | | and I see that there are disks there marked "1541/2031". They look like original combined source for the 1540/1541 and 2031 drives, which makes sense. Only the interface is different.I wish Commodore had used better filenames as it's hard to figure out what file is what. The trick is finding the files that list the proper .LIB lines for the proper interface... Then I checked the MIST64 github and it appears the 1540 source there has the same files.

I didn't yet figure out how to interpret all the files and put together a working source. Some files in this image appear as programs, other are assembler source code. I need to figure out many things about this disk image yet.... > > > On Thursday, February 15, 2024 at 04:36:47 p.m. EST, Francesco Messineo <francesco.messineo_at_gmail.com> wrote: > > > Thanks Spiro, > I'll clone your git and have a look at the code. > Best regards > Frank > > On Thu, Feb 15, 2024 at 9:59 PM Spiro Trikaliotis > <ml-cbmhackers_at_trikaliotis.net> wrote: > > > > Hello, > > > > * On Thu, Feb 15, 2024 at 09:11:46PM +0100 Francesco Messineo wrote: > > > > > 2031 is not on this very good repository: > > > https://github.com/mist64/cbmsrc > > > > > > Does anyone know where I could find a disassembled 2031 firmware?
