I didn't know about the error. I'll have a look and fix the file I have for download. That may have happened during the cut and paste. Sometimes the letters just don't interpret right.
I looked over the loader program in Transactor Vol09_05_1989_Jun. The loader listing matches the program on the disk image. The error is there. In the assembly listing, it shows the correct ROM call. I looked over the loader to try to find the corresponding numbers to change them but to no avail. The loader is strange to me. Maybe some one that actually understands it can change it.
I deleted the file above, so here it is again, error and all.
After getting over my own errors, I found the problem here is the corrected file. Of course now that its incorporated in Wimbasic who needs it . But, here is the file.
