Re: Prevue Channel System Disk

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 does and does not do. perhaps some of the letters corres...

Re: Atari EPG jr reverse engineer

Guess the bottom line is, keep things "modular". :) Anyway, this could turn into a pretty cool project in deed. I can already see people running EPG Jr. in an Atari emulator on their home media center PCs. Just flip over to its window to see "what's on" (with data supplied by yo...

Re: Prevue Channel System Disk

Also the decomissioning report sheds some light on what I now know is called a select code (the NJJR6 bit that I so far thought was some kind of serial number) Oh, cool! I had seen this PDF before (I think it was posted to AtariAge originally) but I hadn't seen the "select code" bit. Make...

Re: Atari EPG jr reverse engineer

Next thing is to figure out what software to send the data with on the PC end? Once the tinkering phase is over -- and If you folks are destined to wind up coding a master application for controlling EPG Jr., I'd recommend writing it for DOS. Reasons: (a) all DOS languages (C, C++, Turbo Pascal, wh...

TCI

So I'm a bit confused about UV's corporate structure. I have read in various places that TCI owned UV, but some places said it was independent, so I'm a bit confused. Did TCI own UV? If so, when did they acquire it? It doesn't really make sense that TCI would own UV, because when UV bought TV Guide,...

Re: Atari EPG jr reverse engineer

By the way, the CGI scripts actually aren't working and default to Altirra no matter what. The if ($emumode == "altirra") is literally returning true even though print $emumode returns atari800. I don't understand. oops my bad, should be ($emumode eq "altirra") cos it's a string...

Re: Atari EPG jr reverse engineer

The timezone, and possbily the DST is sent with the F command, which is similar to the K command, but with $15 values instead of $09. However only the first $14 make it into memory. Ah, cool. Seems the F command is the command that just generally sets the system settings. Very cool stuff. I have a ...

Re: Atari EPG jr reverse engineer

For mode "K" (clock), the data is 9 bytes:- 1: day of week (0 = sun) 2: month (0 = jan) 3: day (0 = 1st, 1 = 2nd) 4: year (presume in hex) 5: hours (in hex) 6: mins (hex) 7: secs (hex) 8: (don't know) 9: (don't know) Is it possible that the two values you don't know represent time zone an...
