TT 3.06 upgrade not working.

Post by markTT »

I'm in the process of upgrading to TT 3.06 ENG/UK. I used ROM splitter to get the right images from the binary and then re-programmed the existing 27C010 EPROMs.

As far as I can tell, the images from ROM splitter are
TTO=EE
TT1=OE
TT2=EO
TT3=OO

sadly though it isn't working (no video). I don't know if ROM splitter has got something wrong. The EPROMs verified OK and I've tried a few different positions and combinations - well I think all possible combinations. For fear of breaking legs on the EPROMs before I get it right, I thought it best to turn to the forum. Does anyone have 3.06 and can do a binary compare if the files are correct?

attachment removed.

Many thanks. It looks like something happened with my EE file. I've removed the attachment before anyone has a corrupt file.
