Quick question

No. The Mega Drive 1 and Master System 1 both use an 8-pin DIN connector for the A/V output, while the MD2, Multi-Mega, Nomad and 32X have a 9-pin mini DIN.

Hmm.. thought not from what I'd read. Just have to cross my fingers, I saw a Megadrive on eBay "2 controllers, all leads plus scart lead" etc etc with a few minutes to go and snapped it up for £8.50 because I need a scart lead for my MD1. Didn't say what model it was so I'll wait and see..
