I have a TRS-80 Model 100 laptop with a bad row driver chip. Looking to see
if anyone has spare parts that they're willing to sell.

Specifically, I need the HD44103BLD driver chip. Below is an abstract from
the technical reference manual page 4.

I may be able to trade spare parts for your own restoration project.

Ref: Page 04 for schematic.
REf: Page 75 for a picture of the pcb.

I've been scouring the used chip market but I've come up with nothing and just bought a dead M100, won't power up, off ebay for almost free. I may be able to swap PCB's to test if that's the case. Otherwise, I will be attempting to restore the other one to factory new.

Let me know,
