the quarterland section from the 1783 book is at www.manxnotebook.com/cd_only/libasd/ln/1783_qt.htm - this is 9 pages of some 44 there are some 173 intacks + 50+ cottages - intacks are described in the first book that contains them (assuming post 1702)
I presume you are happy with Roman numerals (all rents are expressed in these)
I have started to transcribe the 1760 copy of the c.1703 composition book - I suspect that the major parts of both will be on CD_Rom only
