In terribly generic terms, the actual launcher is kinda a big roman candle and the 'smarts' are generally more confined around the capsule, from which any control I/O is kinda routed. Further, the soviet design philosophy has been to keep all the 'smarts' possible on the ground and to actually launch very 'spartan' equipment. Therefore, the soviets could well make great strides in computer upgrades for the system without making (virtually) ANY modifications (at least ones we could see) to either the capsule or launch vechicle. I saw some film of the inside of the soviet lunar module recently. The voice over suggested it looked like a 19'th century steam engine, but I thougt it looked much like the control room of a WWII submarine. The pilot stood in front of about 10 large steel handles, assumeably pulling handles to operate positioning jets.... Even in 1970 I don't think I could have been convinced to ride in this.... al -- Al.
