The 74LS379 can be used either way. Jim ( @Ksarul ) will know what re-wiring/jumpering you would need to do to effect that scenario. ..lee Quote Link to comment Share on other sites More sharing options...

( Up to 32k ) For my purposes , I need to operate out of actual physical cartridges with roms . The non-inverted rom boards are hard for me to obtain ( always sold out ) . I do have a few spare inverted rom boards I can use on hand though . ( Uses the 74LS379 ) If there is an IC that replaces the 74LS379 directly , or with minor rewiring , that makes my boards non-inverting , that would be fine too . Thanks . On the various boards: I always keep a bunch of the bare boards in stock, so they are always available from someone. @arcadeshopper gets supplies from me for his web store, but whenever he runs out, I try to make sure he gets some more. As to an inversion tool, @Asmusr made a really nice tool to invert a set of cartridge files to allow seamless flipping between the inverted and non-inverted formats. I use it all the time, as I build a lot of cartridges and generally adapt the files to fit onto the boards I have built at the time I need to make cartridges out of them. I am attaching it here. bankinvert.zip 4 Quote Link to comment Share on other sites More sharing options...
