No worries, let me know how it goes. I had to script it out, if I repeated that process 9 times manually I was bound to screw it all up.Nice, thanks for taking the leg work out of splitting those ROMS. I will have to try those out.
Same version of TOS? Perhaps try swapping out your roms in known working machine to this one? Besides that would start probing cartridge port area for possible broken tracesI have an odd problem. I picked up another 520ST Cheap that was DOA. It was dead when I got it. I cleaned the pins on u 12 and u15 and straightened all the pins and this got the unit booting to TOS (and incredibly fast too), but it doesnt bother to boot off anything in the cartridge slot. And It will NOT boot directly to a working diagnostic cartridge. The cart works fine on my other 520ST. Any ideas why this 520 ST is ignoring signals from the Cartridge slot?
No, Not sure the version of TOS. I still have the original ROMS from the 520ST I upgraded . Iwas thinking about swapping those. Thanks. I will give that a try.Same version of TOS?

Oh I was not assuming you would!!! simply that I would dump the contents of them and search the CRCs etc to see if they come up on google.I wasnt going to toss them. I wouldnt do that.
Yes.. but the issues are file names showing up distorted. I was able to use the hdd device on my first sysyem when it was tos 1.0 were not talking conpatibility issues.. its just not working at all and that has nothing to do with TOS 1.0If you recall, TOS 1.0 has problems with DOS formatted drives of which your Hard drive SD device may be an example. A better test might be to try the same thing with your TOS1.04 EPROMs in it.
