Does anyone have an original CEGMON?

Does anyone have an original CEGMON rom for C1? I believe the one here has been modified. I peeked the initial power-on values for the "window" parameters and they do not match the ones in the manual (for C1/superboard). The top line is too high on my monitor and when I poke in the correct values the top line moves down. Also, the CTRL-Z key does not seem to clear the screen.

I want to take the source and adapt it to the ACME assembler, which I use (it's cross-platform) and will eventually be able to build from the source, but I'm not at that point yet.

So, if anyone could dump a known good original CEGMON and compare it to the one in the downloads here that would be appreciated!

I did not check the C2 or UK101 roms so I can't comment on those, but it would be nice to verify that those are correct as well.

C4P working, C1P working. 600D Replica working, C4P+D&N floppy not working. 505 board, 610 board, Mittendorf board, TOSIE hacker board need testing, PicoDOS disk untested.
