Dual group DC-4000. Interesting laptop, which has no information about.

Recently, I got my hands on a 1992 laptop, I brought it to working condition, but I did not find any information about it at all.
I suspect it was made in Taiwan, but that's all I was able to figure out. Does anyone know such a brand or is there information about it?

Dual Group was a Taiwanese OEM that manufactured a lot of PC peripherals in the 1980s. They had a US office in Torrance, CA.


(from PC Mag)

According to this snippet they were founded in 1982:


I couldn't find any information about the DC-4000 in particular besides the FCC ID but there's some information (1, 2) floating around about its successor the SKD-4000, which had a lower clock speed of 33 MHz. Could you take some more pictures of it?

I took a look at my old website and found that even a decade or more ago there wasn't much info on Dual: https://web.archive.org/web/20100314163441/http://www.orphanlaptops.com/dual.htm
