History
This keyboard was made by Acer and it uses Acer’s patented switch-over-membrane design. Acer had produced various models in this series, and this particular model is for Data general.

I have acquired this New old stock keyboard from eBay for a very reasonable price. The keyboard isn’t too heavy despite its large footprint. However, the board is built very well and doesn’t creak, unlike other cheap boards.
Acer 6312-k without top caseI am not sure what the keycaps are made of, probably PBT, but the legends are sharp and beautiful. These legends are created using an unidentified method, which was previously misidentified as being dye sublimated. The keycaps are alps compatible and have a chalky matte finish. This particular board has a Spanish layout.
The switches feel very crispy and nice to type on. They don’t sound too loud unlike blue and white alps, rather a bit muted.
The keyboard membrane is supported by a thick steel plate screwed to the switch plate.

At the time of writing, this board is one the favourites in my collection. I love the switch-travel, the case acoustics, quality keycaps and those huge bezels.
