Let me ask a follow up or two if I may:
I understand the old M series lenses can be used in manual mode on the K100, using Depth of Field preview to check the exposure.
My query is about the optical performance; take the standard 50mm M series lens mounted on a K100, would that correspond (in field of view, perspective terms) to a 75mm lens used on a 35mm film camera? Do the 'f' numbers on the old lenses mean the same in the DSLR format - i.e. would you set 1/ISO equiv speed at f/8 for a cloudy day outdoors? What about depth of field markings on the lenses, do they carry over?
