From a photo of the T6963C pins 3,6,7,9 are tied together, it is not apparent whether they go to Vdd or Vss. If it is Vss then maximum vertical resolution would be 64 v-dots, which seems a bit small for a 95mm high display, so I'll assume they're all tied to Vdd.
| Display size selectors (hard wired) | |||
|---|---|---|---|
| Pin# | IC pin | Wired | Value |
| Dual | 54 | ||
| MDS | 3 | 1 | |
| MD0 | 4 | ||
| MD1 | 5 | ||
⇒ 80 to 128, from the physical size most likely 16 lines (128 vertical dot resolution)
| Display size selectors (hard wired) | |||
|---|---|---|---|
| Pin# | IC pin | Wired | Value |
| MD2 | 6 | 1 | |
| MD3 | 7 | 1 | |
=32 character columns (or this would give 80 columns if they're tied low, a bit excessive for this width display and not enough control chips to handle it )
| Display font size selectors | |||
|---|---|---|---|
| Pin# | IC pin | Wired | Value |
| FS0 | 8 | ||
| FS1 | 9 | 1 | |
not sure what FS0 connects to, if Vdd then 5×8 font ⇒ 160 horizontal dots, if Vss then 6×8 font ⇒192 horizontal dots.
