Super old thread, but looks like a '91 I had based on the components (shifters, brake levers, cranks, brakes, rims, crummy plastic pedals, seat qr. Everything I see matches up). The grips and seat have been changed. I think that year they did single color frame/fork with different colored logos. They had bottle cages to match the logo color (had to purchase separately, but they would carry matching ones). My bike was white with blue lettering.

It had a riser bar stock, but not sure if it had that much sweep. The serial number should be useful, right? It's older than this one But you might be able to match the bike's spec if it's more-or-less OEM to the specs on that site. Unfortunately they don't have pictures for bikes as old as yours.
Specialized serial numbers typically start with the prefix 'WSBC,' 'WUD,' 'STT,' or 'STE.' If you don't know where the bottom bracket shell of the bike is, simply turn the bike upside-down and the bottom bracket is the part of the frame that the cranks run through. You will see the serial number stamped into the frame down there.
Some things that can help you date it are the type of stem, and whether Shimano was doing V- or cantilever brakes in the model name you have. Also the number of speeds.I have specialized professional hardrock bike G N 0 6 1 4 0 4 and have no information and only the bike, no decals available. Specialized did have it in their database and registered it however.
