Thumbs up if it works....

Ok thanks so much sir!Didn't we get up to 30 something at one point?
I would just leave it run until you decide to go to bed... Then post how many successful passes we have achieved and switch it off for the night.
I would then remove Nivag's card - and put the CPU back in the mainboard, and give it another run tomorrow.
The more hours we get of successful passes, the more happy we should be...
Dave
Yes Dave, i changed ud8 socket for two timesSo that probably indicates that the problem was related to either your 2K PETTESTER EPROM or the UD8 socket. But you changed the UD8 socket for a good one didn't you?
Dave
You have spoken now to anger the PET Gods...
Great!!! So what can i do again for this pet? Can i try remove nivag a board and run pet with original roms?So, with Nivag's board you actually have everything on board you need:
1. You can switch the NOP link ON to enable the NOP generator.
2. You can use the PET's dynamic memory or you can use the static memory on Nivag's board to replace the PETs.
3. You can use the PET ROMs, or selectively use the ROMs configured into Nivag's board.
4. You can select different ROMs if you have them mapped onto Nivag's board. These include my PETTESTER or different versions of PET BASIC.
So, once you have put Nivag's board into a PET, you should never have to exchange ROMs again (unless they prove to be faulty of course).

You can put all the ROMs back in now, the CPU back in and try to run the PET.Great!!! So what can i do again for this pet? Can i try remove nivag a board and run pet with original roms?
You need a picture of first pettester screen where we can see the checksums, right?Do post #913 first please.
Dave
Hi Nivag, yes in this moment i haven't ROMulator on board....i have only cpu on board!FYI.... FDBF is the Checksum-16 of edit-2-n.901447-24.bin
and
DD67 is the Checksum-16 of 2K worth of 00s followed by PETTESTE2KF04.bin
What would actually being tested would depend on if the ROMulan RAMulator were fitted and if it were which jumpers were in which positions... Assuming that it is currently NOT in the machine then things are looking encouraging.
