Model Year(s) Switches Serial PCB codes Reference Notes
Sony M35 keyboard 1985 (IC) Omron vase spring typical
Omron B3G-S “flat” (function row)
2432094-9, B5Y-C073-401 deskthority.net This is another of those really complicated examples. This is actually two keyboards: a plate-mounted B3G-S keyboard for just the function keys (containing all the logic circuitry), plus a vase spring membrane keyboard with its own PCB for the remainder of the keyboard, each with separate part numbers! (The B5G part number is for the controller/B3G PCB, and the B5Y part number is for the vase spring PCB.)
