ToddUGA Posted October 26, 2003 Share Posted October 26, 2003 Anybody know where I can pick up a 4-port bios chip for my 2 port 5200? I'd love to be able to play every game available for the 5200. Quote Link to comment Share on other sites More sharing options...
CPUWIZ Posted October 26, 2003 Share Posted October 26, 2003 You can replace the BIOS with a 2532 EPROM. Quote Link to comment Share on other sites More sharing options...

ToddUGA Posted October 27, 2003 Author Share Posted October 27, 2003 And last, but not least, who might that person be and how much would it cost? Quote Link to comment Share on other sites More sharing options...
Shannon Posted October 27, 2003 Share Posted October 27, 2003 And last, but not least, who might that person be and how much would it cost? Mr. Wiz has a way of being mysterious... you might want to try asking him to do it for ya. Quote Link to comment Share on other sites More sharing options...
MrRetroGamer Posted October 27, 2003 Share Posted October 27, 2003 I'm sure CPUWIZ or Mitch would be happy to do it, both great guys to work with, and should only be a few bux including shipping, maybe less. It's a good upgrade to do, just takes a little patience to pop the RF shield off first! Quote Link to comment Share on other sites More sharing options...
ToddUGA Posted October 27, 2003 Author Share Posted October 27, 2003 Ok. CUPWIZ, can you please burn me a copy onto a 2532? Send me a private message if you would like. Quote Link to comment Share on other sites More sharing options...

ToddUGA Posted October 30, 2003 Author Share Posted October 30, 2003 CPUWIZ, any news on whether you had a real 4-port bios rom? Quote Link to comment Share on other sites More sharing options...
Bryan Posted October 30, 2003 Share Posted October 30, 2003 I've been hunting through the 5200 forum history and I can't find the topic I'm looking for. What exactly is the compatibility issue with the 2-port BIOS? Did they move the RAM vectors or just the locations in ROM. -Bry Quote Link to comment Share on other sites More sharing options...

Bryan Posted October 30, 2003 Share Posted October 30, 2003 Ahh.. I'm thinking of writing for the 5200, but if I just capture the RAM vectors and avoid jumping into the BIOS, all should be well. -Bry Quote Link to comment Share on other sites More sharing options...

I enjoy playing around with the 5200 even more than the 2600. Plus it's not too hard to port over to 400/800/XE Quote Link to comment Share on other sites More sharing options...

That works until Atari changes it again. Since the vectors are all placed in RAM during boot-up, I see no reason not to just use those addresses. -Bry Quote Link to comment Share on other sites More sharing options...

ToddUGA Posted November 3, 2003 Author Share Posted November 3, 2003 Hey CPUWIZ, the 4-port bios arrived today (pretty fast service!). I'm going to try and install it tonight. Is the bios easy to find on the motherboard? Can't wait to give Pitfall a try. Quote Link to comment Share on other sites More sharing options...
