I am one of those fortunate to own a Lightning ST and I have TOS 2.06 perfectly working on a plain ST. You do need 1 mbit EPROM’s and those are 32 pin. To get it working and to still be able to close the case, some soldering is needed.I could write up a bit of a tutorial. The board I did this modifications on is the same as yours. You could even make 256 kb EmuTOS working with the Lighting ST.

OK thanks for the ideas.

So, I could buy these and use 1.04 TOS until I get Lightning ST board.

STFM KIT DUAL TOS & UBE BETA
DUAL TOS ROM 1.04/2.06 USA £10

But generally saying, I don't solder, others do that to me and I just get my st back from memory modifiation and cpu socket installation.

What kind of soldering this would require?
