Help - Nokia 2260 LCD data? Is there a Nokia 2210? Euroguys' input?

I'm making a few (cuneiform) sexagesimal desk clocks out of clay.

Hence I've been trying to find some cheap LCDs in old TDMA phones (LCDs from Spark Fun etc. are $9 vs. entire phones from eBay

Sorry I don't have any answers to your questions, but I found it quite coincidental that I was listening to David Gray's "Babylon" while reading this message. I never could understand that unwritten decimal place. Please let us see the final pic on a.b.s.e.

The schematic is very simple - not interesting, even. It's just an MSP430T2012 target board wired to two pushbuttons, a battery, and the LCD. It's the firmware that's interesting, and the clay housing. I'm using a kind of synthetic terra-cotta ersatz clay called DAS (air-dry, not fired).

The clock is really just a stepping-stone project (no pun intended) to a calculator, by the way.

Progress has been made, though. The pinout is definitely the same as the Nokia 6310/6310i LCD. However the LCD itself is very different;

84x48, and the driver appears to be a PCF8811. This morning I determined that latter fact the hard way; i.e. with a storage scope, triggering on _RESET and hand-decoding the data coming down the SPI bus, then comparing this to the various datasheets for candidate parts.

At powerup, the phone asserts and releases _RESET, then sends:

D C76543210

010100000 (Mirror X =3D 0) 000000000 (NOP) 000010000 (set X addr =3D 0) 010110000 (set Y addr =3D 0) 100000000 x84 (write data byte) 000000000 (NOP) 000010000 (set X addr =3D 0) 010110001 (set Y addr =3D 1) 100000000 x84 (write data byte) 000000000 (NOP) 000010000 (set X addr =3D 0) 010110010 (set Y addr =3D 2) 100000000 x84 (write data byte) =2E.. etc to clear the screen

In passing, I should remind everyone to delete old text messages off their phones before returning or recycling. I'm tempted to SMS a certain gentleman in New York to ask him if he and "Princess" really did get to do what he was proposing on New Years' Eve of 2005.
