This is straightforward. Brian has already pointed you to Randy's site which has the usual instructions for salvaging a 2600 2K or 4K cart. (Look for Pac-Man carts, they are ubiquitous and nobody will care if you destroy one :-) I will give you a piece of advice, before trying to make a distro cart make a "frankencart," that is a cart with a socket. That way you can burn & test eproms without soldering them in. It's also a cool way, if you have a PROM burner but no supercharger or cuttle cart, of playing games you download as .bins on a real 2600. BTW the best way to get a PROM off an Atari cart circuit board is to snip all the pins with a sharp pair of side-cutting pliers, then desolder the pins one at a time. The boards themselves aren't too well made and are more important than the 87,000,000th copy of Pac-Man you'll be mutilating. --Roger Williams P.S. If you're wondering why you need the 7404, Atari in their wisdom decided to wire an address line to chip select on the PROM so it's positive-true instead of inverted as was standard for ROMs in those days. Of course Atari found it cheaper to have mass quantities of non-standard ROMs made than to add a chip to the console so standard ROMs would work. ---------------------------------------------------------------------------------------------- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
