Help to identify multifunction CT-6050 card

[soviet9922]

Found some kind of ram card and like to use it on my XT but can't find the manuals to learn how to set the ram etc.
The cards say "CT-6050 MULTI FUNCTION" and "copyright 1985" on the back "made in taiwan".

Searched on google and stasons but found no card like it, maybe somebody knows about it if is a clone, or where to get some documentation ?.

By the logo, I presume that the maker is Twinhead International Corporation. I see at [here] that Twinhead made a CT-6280 card.

Cool, searched also about twin-head but had no luck, the ct-6280 is very different and has only a single row of dip switches.
