I've played. The tech situation has somewhat improved with a 7fer.
The turnlog.
Turn -1: 1275 BC
We are researching writing in 9 at -3gpt, 34g in the treasury. CiVAssist tells me that indeed everyone we know is up IW, Writing, Math and Myst, except Persia, who does not have Math yet. I try to get some cash for trading techs by the "banking trick", buying say 300 gold from India for gpt but they don't bite even if I raise the bid to 20 gpt. Later in the game I discover that somehow at this stage of the game the AIs want something like a 40% interest on loans. Why is that? From what I've read I always thougth it was around 10-15% with a clean rep.
Check all cities. Hlobane needs some growth applied, now only 1sfpt. Isandlwana growth in 1 but worker in 2, MM to both in 1, reassign a wheat to Ulundi, which will now grow in 1.
IBT
Zimbabwe: impi -> impi
Bapedi: impi -> impi
Isandlwana: worker -> impi
Then it's Wonder time:
ToA is being build by: Rome, Egypt, Persia.
Mom is being build by: America, Egypt, India, Carhage.
Oracle is being build by: Rome.
And last but not least: SoZ is being build by Arabia in Kufah!. Yay! The Arabs are preparing a prize for us when we conquer Kufah!
Turn 0: 1250 BC
We are doing -4gpt now. But I can lower the lux slider to 20%, after MMing Mpondo for happiness by assigning the fish (rax still in 1). This gives +1gpt.
IBT
Mpondo: rax -> impi.
Egypt are also starting SoZ. 
I was being too optimistic about the Arabs building it for us. I later realize that "loosing" SoZ to a cascade is also a realistic option.
Turn 1: 1225 BC
Check cities, possible trades, workers, move scouts, nothing special.
IBT
Hlobane: impi -> archer.
Mecca completes Oracle. A lot of wonder build switches. The most important one is the message that Egypt are now aslo building SoZ, which they already were doing last turn, so this must be a switch form the Oracle. Cascade? Not yet. Well, Carths complete GLH.
Turn 2: 1200 BC - zzz.
IBT - zzz
Turn 3: 1175 BC
Mainly routine checks. Zimbabwe is about to grow but will also complete impi on IBT, so no happiness issue.
IBT
Zimbabwe: impi -> archer.
Turn 4: 1150 BC
Mpondo will grow and riot next IBT, hire a geek there.
IBT
Horses connected!
Scandinavia demands 20g. I cave.
Ulundi produces settler (on growth to 3) -> horse.
Bapid: impi -> woker (completes on growth to 4).
Move impi from Bapedi to Mpondo for happiness. Sorry, should have done this last turn, didn't realize impi have movement 2. I never, like never never, play the Zulu.
Turn 5: 1225 BC
Switch archer build in Zimbabwe to horse.
Can get 1 turn off writing (3 -> 2 turns) by moving sci slider to 80%. Scouting impi doscivers a small Scandinavian stack (2 archers and a warrior) near Hlobane.
IBT
Silks connected
Turn 6: 1100 BC
Scandinavian stack moves towards Hlobane. For this reason I do not change the archer build to horse but let it complete in 1, just in case.
Can lower lux slider to 10%.
Swazi founded -> rax.
Science back to 70% - writing still in 1.
IBT
Writing comes in.
Hlobane archer -> horse.
Isandlwana rax -> horse
Turn 7: 1075 BC
Discover the possible 6fer trade as described in
post 102. Stop and consult team. Then make the deals which turn out to be a 7fer since polytheism is also around.
Dutch: CoL for 28gpt + 3g.
Rome: Phil +117g for CoL.
Scandinavia: MM + 83g for CoL +Phil.
Carthage: spices, Myst , 55g for CoL.
Portugal: Poly for CoL + 40g.
Persai: IW for Col + 55g.
Egypt: Math + 5g for CoL.
That's 7 techs! This is without a doubt the best deal I ever made. On emperor I am just never that far behind.
Tech parity now? No! The Dutch (only) have construction; The Ports and the Arabs (only) have monarchy. Both are too expensive for us (in the order of 900 - 1000 gold).
Set research to lone scientist on republic. I hesitated between republic and literature, but choose republic because if that fails to be of trade value it will at least give us the most expensive AA tech.
Since we now import spices from the Carths (they put that on the table on their own accord) the lux slider can go to 0%.
We have some 180 cash now so we are in for a demand. I decide to buy some embassies, with two likely allies in our Arab and American wars to come, the Romans and the Scandinavians. Screenies below.
IBT
Zimbabwe horse -> settler (will complete on growth to 6)
Bapedi worker -> horse.
Arabs establish an embassy with us.
Portugal completes MoM. No cascade.
Turn 8: 1050 BC - zzz.
IBT
Mpondo impi -> worker.
Ngome walls -> rax.
Here comes the cascade:
Rome is building GW.
Arabs build HG.
Egypt competes ToA.
Duth are building GW and complete it.
India are building HG and compete it.
Turn 9: 1025 BC - zzz
IBT - zzz
Turn 10: 1000 BC - mover workers, not much.
Hand off notes: some of our larger cities should probably build another settler or 2 after the next builds complete.
Construction and Monarchy are around but not widely spread yet but they are still far too expensive for us. Maybe we can make loans but I even doubt if there is enough money in the market to buy either tech.
Some screenies:
Rome:
Trondheim:
