Got a hold of two VIPCO displays (120x32 red pixels), which currently are not working yet.
Specs
- 120x32 red LEDs
- Driven by HD64180RP6 datasheet
- Controlled by RS232 and probably RS485
- display works per 2-line driven by TIP107
Other ICs (vertical control)
- ULN2003A (High-Voltage, High-Current Darlington Transistor Arrays datasheet)
- CD4514BE (CMOS 4-Bit Latch/4-16 Line Decoders datasheet)
Other ICs (horizontal control)
- ULN2003A
- HCF4094A (8-stage shift and store bus register with 3-stage outputs, datasheet)
Pinout =
While the PCB segments are designed to first shift in data for the top 16 leds (24 wide) and then the bottom 16, at least the display without serial connector is modified to use 2 bits per clock (top and bottom half).

Where:
- VCC is roughly 7.8v without load
- data1 is top 16 LEDs shift register
- data2 is bottom 16 LEDs shift register
- A+B+C+D is row select
- inhibit is the row 'strobe'
