A favorite of mine is the AECrom, due to its excellent curve fitting engine (CRVF) and some other goodies. But, the AECrom is a strange beast - when used together with my NoV-32, it occasionally locks the calc when I turn it ON. This only happens with the AECrom. My suspicion is a conflict at start-up as the AECrom does funky business if you press and hold the ON key (it switches its modes between inches, degrees etc).
As the original AECrom is in conflict with the NoV-32, I decided to copy the rom (with the COPYROM command) from page #E to page #A (I already disconnected pages #A and #B from the HEPAX chain as explained in the HEPAX manual. I use page #B for my own MCODE rom project).
Now strange things have occured: Cat 2 displays strange symbols instead of the anticipated AECROM, but if I press ENTER right there, I do get the functions inside the AECrom. But after such a CAT 2 the calc goes apeshit (locks, funny characters, high pitched sound on key press etc). Trying to access the functions, I get interesting messages like AECROM-32 (seems like an error message). I have cleared the polling addresses after copying the rom, so it doesn't lock the calc when I turn it on anymore (now, that's the good news), but I'd like to repair the newly copied beastie-rom so that it becomes my favorite AECrom residing nicely in my NoV-32 ram.
Any takers?
