WTB: Updated BIOS for Atari 5200 4 port to 2 port compatibility

[Wyluli Wolf]

Before I resort to buying a 2532 EPROM off of eBay to program, I thought I would check to see if anyone has a BIOS chip available for the 5200?  Console5 is sold out and has been for awhile now.

I have a 2 port Atari 5200 and would like to be able to play all of the original carts on it.

Just let me know price and shipping cost.

I do 4 port eproms with custom character sets! The text looks better, more computer like.

I have 2532's on hand and can program one or more if you like. I have no 5200 but from what i read the 2K bios goes in the high half of the 4K EPROM.

 

2532's need an adapter to program in a TL866, and luck that the chip will program with below spec voltage, since they are usually 21 or 25v, and TL866 often tops out at 16-18v in reality without external help...

 

Pm if interested.
