Series
FKB8725 Series
104-key and 105-key variants, offering DIN-5 and mini-DIN-6 connectors. The difference between FKB8725 Series and FKB8729 Series is not known. The Fujitsu logo is optional.
FKB8725 Series was classified as “Low” on the Fujitsu Takamisawa website in 1998. Model FKB8725-651 was classed as a Fujitsu Value Keyboard, and is depicted as ANSI layout. A PS/2 adapter is included, suggesting that FKB8725 Series has an AT plug fitted to the cable (adaptable to PS/2) while FKB8729 Series has a PS/2 plug fitted as standard.
FKB8729 Series
All models use the PS/2 protocol with a 6-pin mini-DIN connector. Model numbers with a “/20” suffix are also RoHS compliant; the non-RoHS models are PC99 compliant (purple plug) while the RoHS version does not appear to comply with PC99. Strangely, there is no Swiss RoHS compliant model given in the datasheet.

FKB8735 Series
FKB8735 Series is the Fujitsu ValuePlus Keyboard, also referred to as ErgoTrac Keyboard.

The keyboard appears to provide a DIN-5 AT connector with a PS/2 adapter, with an additional DE-9 plug for the RS-232 serial connection for the ErgoTrac.
FKB8735 Series was classified as “Medium” on the Fujitsu Takamisawa website in 1998.

FKB8750 and FKB8755 Series
FKB8750 is an ergonomic sub-series, where most of the keycaps of the alphanumeric cluster are angled inwards. The left-hand side (1–5, Q–T, A–G and Z–B) have keycap faces rotated approximately 12–13° clockwise, while the right-hand sides of these rows (6 to =, Y to ] etc) have faces rotated approximately 12–13° anti-clockwise. This can be seen for example in model FKB8754-501.
FKB8750 Series covers the pre-Windows 95 versions, and FKB8755 Series covers the Windows 95 versions. FKB8754-501 is an anomalous model, having Windows keys but being in a lower series number of FKB8754.
