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 its Vss then max 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 ⇒196 horizontal dots.
