I've got two Amiga which need them: A CDTV and an A500, both of which have 1.3 ROMs in them. I'd be interested in doing the 3.1 ROM/new support ROM hack to the CDTV, but that's for another thread.
Meanwhile, I'd be happy to pay for one or even two original WB 1.3 floppy sets that still work. USA ones would be preferred, although I have a German 1.3 disk that more or less works, when it works. I understand 1.3.3 has a few extras that are CDTV specific, unless I'm mistaken (infrared port driver for CDTV specific IR mouse?).
I hope someone can hook me up. Thanks!
