Post subject:  Info needed for Hyundai HG12602-A 2xHD61202 1xHD61203

I recently pulled this LCD out of an old RAM tester I had

Manuf/Model: Hyundai Korea HG12602-A

The 3 controllers on back are:
2x HD61202
1x HD61203

Just wondering how to hook this bad boy up, I scoured the internet left and right, and could find a data sheet from hitachi for a HG12601 (http://www.hylcd.com/products/main.html?pg=detail&product_id=P000000022 but not the 602-A.

Its interface is 20 pins for hookup, any help on either pinouts or how to hook this up to a parallel or serial interface would be GREATLY appreciated.

20 pins is normal for this controller but there are few different pinouts used. You could try looking at the pinouts in this forum for KS0108 and HD61202/HD61203 and then taking the chip datasheets and testing with multimeter where the pins go.
