Hello everyone. Recently I've acquired a very old Commodore 386SX-LT laptop, made ~1990. I can get it to power up, the HD Power and FDD lights come on, and the LCD display lights as well. It even seems to POST with a single beep. However, nothing is displayed on the screen. It has a VGA port in back that I've connected to a monitor, but still black screen. I opened it up to find an empty socket on the motherboard, so now I'm thinking someone plundered the graphics chip. Problem is, there is VERY little info out there on this machine, nevermind a schematic. So I'm hoping someone out there can help identify what this empty socket is for. Here's the only specs I could find on the graphics abilities of this dinosaur:
9,5" monochrome LCD (VGA)
640 x 480 pix
80 x 25 chr
8 gray shades
If it is a VGA chip thats missing, I'm hoping someone can tell me what model it might have been. This is right around the time (I think) that the VGA standard was being adopted as the standard, so I don't think there was a lot of selection for graphics adaptors. Heres a photo of the board, the empty socket is in the upper right corner.
