Dual SKD-4000 (SKD 2)
The Dual SKD-4000 II is a 486-based generic/ODM laptop that was released around March 1994. This laptop is a revision on the original SKD-4000 from 1993, with the only spec difference being the inclusion of Local-Bus video, according to Dual. It also seems to have added support for some additional processors.
