Question Olivetti BA2030 motherboard for M300-30 not working

[fabry892]

Hi, I have an Olivetti BA2030 motherboard for a m300-30 486 sx pc that does not start. The power supply works correctly. When I turn it on I do not hear the beep from the speaker. I think it is a problem with the bios chip that does not start, but I do not know how to solve the problem. I also attach a photo of the card that mounts a graphics processor with some damaged pins, but for that I have already found an external ISA video card, but if connected to this card it only gives a black screen. If possible, how do you think I could solve the problem? Thanks to anyone who will answer me.

Where I am not familiar enough with those era to offer any other suggestions, I would look very closely at all the capacitors on the motherboard and make sure nothing is swollen or leaking. I would make assumptions about cleaning all edge connectors and so on.

Just curious, really, but is this just a "for the heck of it" or do you have a real world use case for that old thing?

Hi, there are no leaking capacitors. I also tried cleaning the removable chip pins, but it doesn't change anything.
I'm interested in fixing the PC to block a childhood memory.

More power to you, for sure. I watch a channel called "Mike Tech" on YT where he takes these old systems and gets them up and running. IDK why but I find it quite chill.

Thanks, I'll take a look.

You might be able to locate a bios rom image somewhere on the interwebs. Then you would likely need an eprom and a programmer. A friendly electronics person/colleague/shop may be able to help with a programmer device but identifying the eprom type and finding a bios image is going to be tough.

Looking at your posted picture, the WDC controller appears to be physically damaged, to the right of the memory sockets…

The package is broken in your image and the surface mount connections don’t look right. Problem is that the image resolution doesn’t show that chip in detail.

Can you take a picture of the WDC chip please, show the surface mount soldering around the damage?
