Hallo William, > I have added DOS version numbers to you list as follows: Thanks. > You should be able to switch the ROMs and 6530 to the working board and > the system should run. If not, one of the ROMs or the 6530 is bad. > > Remember: you must use the correct 6530 for the ROMs. > Be careful not to mix ROMs from differemt versions. > UK6 is the GCR ROM. It is the same for all versions. > If it is defective, you will not be able to read or write. I will take my own 4040 and replace its chips with the DOS 1 versions to see if this will work. I already saw that there are images available at FUNET so if the system won't work again, I can check the ROMs. Only have to find a way to check the 6530. I'm not at home right now so I cannot check the manuals. The difference between the 3040 and 4040 is the number of sectors on a some tracks. Therefor I thought that I would find at least different images for these machine, not only different DOS-versions. I will dig up my 3040 (litterally :( ) to check the ROMs. I'll you know.
