Just want to remind, take care when you remove socked chips from the MTX mainboard, those chips may not have been out for many years, and kind of stuck there. Today I ran into a problem, and I wanted to swap the VDP, suddenly I discovered on of the pin was broken, it was left in the Socket.
When the chip is removed from the socket it do help to spay with some contact cleaner.
I saved the VDP by soldering a new PIN to it......
- VDP out of the socket, the chip can be very hard to get out, take care!!!
