The SKB-5050 was an AT keyboard produced by Podworld¹⁾ and was presumably the predecessor to the SKB-5150.

Currently, two versions are documented: a standard US English SKB-5050 fully produced by Podworld and a Russian SKB-5050 that uses a third-party PCB.

The keyboard consists of three parts: a ABS top and bottom case, and an internal assembly

Externally, it has a pen holder and a lock-light sticker in the top-right corner.
Internally, it has threaded plastic standoffs for fastening the top and bottom case together and for fastening the assembly to the top case.

Externally, it has an AT/XT switch cutout, a QC sticker, a “sup” sticker (likely a date of manufacture sticker), and a sticker with the model number and series number, which is likely a serial number. It also has six total feet: two flip-out feet and four non-slip feet Internally, it has a cutout for the DIN-5 cable.

The assembly consists of a PCB and a painted steel switch mounting plate that is cross-compatible between SMK Vintage Linear and Cherry MX.
The top of the PCB has a PD-18 marking, and the top of the switch mounting plate has SKB 5050 stamped into it under where the spacebar would go.
The bottom of the PCB has a PD-18 marking and a sticker of unknown use.

The keycaps are made by Tai-Hao in their TH profile and are a mix of ABS doubleshots and pad-prints.

picture notes: US English SKB-5050 is missing a caps lock keycap, has third-party templates and the switches were desoldered by the owner of the keyboard.
