Thanks Geoff I appreciate your help!

I see my Tatung Einstein MOS is V1.1 as it happens. I'm not sure how
you do a ROM dump like Chris did, is it quite easy? I've had sporadic
success with certain COM files, whilst others seem to load but the
game freezes for some reason.

I've transferred over images of 4 different DOS versions to test with
each COM file... but no change. Very strange!

I managed to transfer the Konami 4 game pack successfully and it
seemed to load, entering into the menu screen... I almost fell off my
seat... but it doesn't load any of the games... bah!

Anyway thanks for your help again, I'll keep plugging on!

Regards

Mario
