I'm sure someone else knows more, and there's probably a resource, but here's what I recall.
The first road frames were all pretty much the same and came in some fairly garish colors. The bottom frame was a pinkish purple, also there was a Miami Vice pink euphamized as "coral" some really vibrant greens... etc.
These frames all had a nominal wheelbase of around 39" for a 23" frame, and had eyelets on the rear dropout (none on the fork). The R300 or 400 had Diacompe aero levers and Suntour Cyclone derailleurs with a 14-24 6 speed freewheel.
The eyelet disappeared for either one or two years in 1987-1988 or just 1988. In mid-late 88 they introduced the "criterium geometry" with a cantilevered rear dropout. After that I lost interest and didn't pay attention anymore, although I think the 2.0 frame might have appeared around 1990.
It was impossible to find a non-biopace bicycle in 1988-1990.
Similarly, indexing became non-optional around 1986. (I know, I know: "wah").
The first "Black Lightning" I saw was in the either the fall of '86 or spring of '87. It was gorgeous, but I recall thinking it a little pricey for the component level. Suntour Superbe, but not Superbe pro? I dunno for sure. I'm thinking they ran around $650 that year, while an R-400 (or whatever the bottom level was) came in around $400-450.
I especially liked the first gen road bike because you could put a rack on it for long, fast rides in indeterminate weather. Losing the eyelets... makes for a pretty toy, but much less of a bike, IMO.
I sold my 88 frame with a mix of Campy components and two sets of wheels in '02 for around 290. It was a great bike, but I don't really miss it. Well, except to look at, and that's just goofy.
