I bought a dead Compaq Portable 386 with the expansion box last week and after about 26 hours of tinkering with it, and a DOS Re-install it now boots to DOS 6.22.
After all of this, only 2 problems that I can determine at this time remain:
1.The internal display has a red vertical line going through the screen.
2. When I try to use a VGA card in the expansion box, I get no video output, it uses the internal screen and the video cards BIOS doesn't get displayed when the computer starts.
What I want to do with this machine is use it as the portable it was meant to be, and as general use 386 machine with Windows 3.11, VGA Graphics via external display, and a Sound Card.
The VGA card is a 16-bit ISA EGA/VGA combo cards it was manufactured by Ahead.
These are the only pictures I can find of it.

The only difference between this one and mine is that mine does not have the empty sockets for more video RAM, there is just a blank PCB there with nothing soldered to it.
The Machine has a 100MB Hard Disk, 6MB of Memory, and the 80387SX Co-Processor installed.
Any help or insight on these problems would be very appreciated.
