Master System help anyone?
« on: December 20, 2015, 14:23:38 PM »
I have bought a non working Master System which is supposedly due to a BIOS fault. Looking around the net I have yet to find a replacement other than one which requires an eprom programmer and wasn't very clear on what was needed to fit it in.
Any clever people here know anything about MS BIOS replacement?

there has been a few members here focused on the technical side of things, but I don't know they still come to RVG t present, I think your best bet is some the mastersystem Facebook pages or strictly deadicated Master System forums. As to mention that sites like Console Passion may be able to help, but that won't be free.

Hopefully somebody will be able to shed some light.

How sure are you its the BIOS pal? You will need to reblow the eeprom if it is that.

Other than that check these out. The schematics are a must.

Here are some things to look at for potential guidance:

Thanks guys, I will look into the links. I only have the word of the seller that it's  the bios, but need to do some digging.
