Re: Prevue Channel System Disk

Just to expand a bit more on this particular subject.... The select code on our dumped ROM is NJJR6 (btw that's where that came from) and I was initially surprised to see them so similar, hence my thought that it wasn't a unique serial number, rather a bunch of letters that indicate what the system ...

Re: Atari EPG jr reverse engineer

Is it possible that the two values you don't know represent time zone and daylight savings time? I ask that because they seem to be two parameters that are displayed by the settings screen of the EPG Jr. I know they definitely aren't timezone or DST, as the clock bytes are stored in the atari memor...

I can test this on real hardware.. When I send serial data from tm PC through an SIO2PC interface into my 130xe's SIO port, with the Prevue cart running, you can see the little DATA cursor flash.. And.. I have my 130xe hooked up to a video capture card on my PC.. So I can send strings of data into ...

cgi scripts for calculating checksums

Here's a bunch of cgi scripts written in perl to generate the content for the 3x modes I currently know about. I've just installed Apache and Activeperl and dumped the scripts in C:/program files/apache software foundation/apache2.2/cgi-bin and they work without further modification - of course mile...
