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.
My collection: 1040 STE, TOS 2.06, 4 mb, CosmosEx - 520 STFM, TOS 1.04, 4 mb, Blitter, CosmosEx - 520 STFM, TOS 1.04, 4 mb - 1040 STF, TOS 1.04, 1 mb, Gotek - Amiga 1200 with Blizzard 1220/4 - Amiga 500 + ACA500 - Amiga 500 + TF530, 1 mb chipram hack.

Atari 8 bit: 800XLF, stock - 600XL, Ultimate 1 mb, Sophia RGB - 130XE, 320 kb, Sophia RGB

Sinclair stuff: 3x Spectrum 48KB, Clones: Harlequin, JS128, Nuvo128 and Issue3B replica.

Ultimate64, a few C64 breadbins and Pi1541 for storage.

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?
