My personal dwarf breeding project has finally reached the desired result: on the 4th of Galena 1083, ònul ósoddom gave birth to Ingish Vabôbokun, her first daughter. ònul is the daughter of an engraver (who never set foot underground) and a clothier, her paternal grandmother is Rith Asteshdumat, matriarch of the aboveground fort. ònul's husband, Urist Ecemtulon, is the grandson of Rith on his mother's side - the two have the exact same four grandparents. Little Ingish does seem quite healthy in spite of the low ancestor count.
I just let the fort run in the background with minimal supervision for the last few days, because there was nothing left to do but wait; i'd already walled the settlement off, built an automatic watercannon that kept nuking wandering wildlife, trained all adults in a bit of crossbow use and just kept everything ticking. FPS was seriously deteriorating - under 30 at 120+ dwarfs (Ingish is Nr. 145, but FPS had been poor for years).
Total value generated is just under 13 Mio. in 30 fort years, with absolutely no metal industry. The belowground fort ran mostly on autopilot, just creating food, drink and clothes for themselves. Somewhere in year 26 or so, the last mined stone ran out, and in year 29, their brewery stopped distilling for lack of containers. Everything was set up with large party halls and enough beds and tables for everybody, so everyone's still ecstatic down there. Not to mention the ~30.000 drink and ~25.000 prepared food and about 1100 of each clothing item they hoard. That must have been a major cause of FPS troubles - whenever i set up, deleted or changed a stockpile, FPS dropped into the single digits for about half a minute before recovering.
The aboveground fort got one axe, three stones, one block and a dead wild boar as starting gifts and based on them a fully self-sufficient surface fort with thriving animal husbandry (wolves, wombats, wild boars), beekeeping industry, legendary engraver and jeweller in spite of never digging a single tile and having no trade, and a few multi-story buildings and a complete fortification ring all made from raw clay taking up about 1300 lumps. The fort is 35 dwarfs strong now, ten of them adult. (110 dwarfs live in the below-ground settlement.)
I was waiting for the birth to have conclusive proof that cousins can marry and reproduce, but making it to the third generation of fort-born dwarfs is also a nice final achievement to shelve the place with.
PS: in other news, the concept rig for the dwarfputing mass storage device passed its function test. Using carts in eight different weights to hold information and reading those weights out (with four plates per cart) would allow storing the equivalent of three bits per cart, and this storage device can handle blocks of seven carts with a single pressure plate and bridge. The supposed organisation in sixteen-cart blocks (equivalent to six bytes or one "frame" of video data for a 6x8 pixel monchrome display) would take one plate and three bridges with links per block, so seven mechanisms per six bytes stored data. The read-out would obviously take four linked-up pressure plates for each of the sixteen positions, about two hundred total, but that's a one-shot cost; you could store an arbitrary amount of data in sort of a sixteen-track data tape, and five hundred blocks would hold 3KB of data, at a cost of a paltry 3700 mechanisms (reading track already included). But it'd also require making, selecting and placing 8000 minecarts. And it would just be storage, you couldn't (usefully) write to it, rewind it or search for a place on the "tape".
