Is that to say you haven't found a datasheet for the panel, only the ICs?
I have not found much electrical spec about UG-32F01 other than the one posted at the beginning of the thread. I do have experience interfacing to modern 128x64 OLED display over I2C bus; like you've said, it takes in pixel data and continuously update them by itself so no need for constant refresh. The UG-32F01 does not appear to have the self-refresh capability

A cursory glance at the 6255 sheet (I found it here
https://www.pjrc.com/tech/eg64e00bcwu/msm6255.pdf does seem to show it has the right outputs to suit the 14 pin connector on the display.

That's the job of a controller, and this display doesn't have one. It only has the drivers. There's no memory, except for the shift registers that can only hold a single row or column.
That's my understanding of UG-32F01 as well. The easiest solution may be getting a controller like the MSM6255 Martin A mentioned, but I was wondering whether anyone has built his own controller out of 6502, FPGA, CPLD, or even TTL logic.
Edit: A LCD controller needs additional memory to hold display data plus interface logic to work with a microprocessor, so replacing LCD_controller+memory+interface_logic with a processor+memory+CPLD is not entirely illogical.
