I've been offered a Quantum 105mb 3.5" hard drive which I would
like to place in my IIfx enclosure in the space where the 2nd floppy
would go. (I've already got an Apple 160mb drive as internal drive 0.)
Can anyone tell me what extras pieces I need and where I can get 'em?
Thanks.

Parts to make one of your own should be about $10; alternatively, you may try spicing a female connector onto the existing cable and, if you have another two-ended scsi ribbon cable, hook the extra hard disk to that. I've never tried this and suspect it may cause noise problems, though. Make sure you terminate only the last drive on the cable (terminating resistors are on the drive controller card near the scsi connector in single-inline-pin (SIP) packages). Then make sure both scsi ID's are different; this is controlled on most Quantum mech's by a series of 3 jumpers. Usually all unjumpered is "0" and some counting scheme gives the rest of the ID's. As far as physical mounting, it's been mentioned on the net before that the mechanism probably has screw holes in it so all you have to do is drill the appropriate holes in the hard disk mounting bracket; but mine is mounted with Velcro (TM)--wonderful stuff; no problems at all. On a semi-related note, I'm getting depressed pricing the FDHD options for my Mac II. Fry's electronics sells the raw mechanism for about $200, but not the SWIM chip; and certified APPLE gougers (oops, dealers) want $450-$500 to *replace* (not add to) my existing 800K mechanism with a new one and add the new controller chip. So... Does *anybody* have any idea how I can get my hands on a SWIM chip? Does anybody have a broken II[xci] (or one going in for a IIfx upgrade) who would be willing to part with (swap, trade, sell?) the SWIM chip? I can't see how this would be illegal, but I suppose that for even mentioning it I'll hear from APPLE corporate legal representatives or some such.... glen rosendale cypress semiconductor gbr@cypress.uucp
