In particular, I think the December or January '85 issue of A+ describes how to make the Uni 3.5 work as a Mac external drive, which presumably will make it work with a GS and Diversi-Cache. As for myself, I'll just avoid software that doesn't talk to my smart UniDisk. BTW, since we're talking UniDisks, I'll ask my usual question: Has anybody hacked their LIRON card to make it possible to daisy chain any Apple drive (both the 5.25 and 'dumb' 3.5's, in particular) to the back of a //e-based UniDisk 3.5? I'm not excited about disassembling the ROM and figuring out how to uncripple it and make it look like the //c protocol converter code, particularly. And of course, just replacing the EPROM is hard because Apple didn't use a socket. Grrh! Does anyone out there have a used //c reference manual [with protocol converter firmware listings] that they'd like to sell, cheap? I'd also be happy to see schematics to figure out the differnces, but I should be able to assume that the circuitry is more-or-less the same. -- - Ralph W.
