Nearing the completion of the remaining three integration boards - there'll be four of these boards in total, each with two integrators, giving eight integrators in one 4U rack. The integrators can be operated either as integrators or summers - via toggle switches on the front panel. The plan is to also have four dedicated summers and a couple of multipliers in the rack unit. Plus the control unit rack, plus a coefficient potentiometer (20 off) rack. When these three racks are finished (early(ish) next year?), I'll have a usable analog computer - then follows the really interesting construction of a special functions unit...(I have some ideas for the usual suspects (sine, cosine, tangent), plus (of course) I'd like to have all the hyperbolic functions, not to mention all those due to Messrs Bessel, Struve, Hankel et al).
Quite a lot of work piling up!
