A Golden Time Corp. portable/luggable system from Taiwan, from the 80s. It was designed by Kuno Tseng but not much more info is available.  Inside the case is a very nice amber 7 inch CRT (12V supply), which produces a crisp, flicker-free image. The power supply supplies 12V, 5V, -12V and -5V. There is space for 2x 5.25" drives. The plastic of the case is not the least bit brittle and seems very robust. The keyboard is probably for the XT, which may cause problems for an Apple II convert. The motherboard was installed by user from an Apple IIe.
