8-inch substitutes

So, back to my 8-inch drive problem... Would a Shugart 851 be an acceptable substitute for a Qume 842? The client tells me that any of the following will work in his Fairlight CMI synthesizer: Qume 242 YE Data YD174 YE Data YD180 Mitsubishi M2896-63 I'm not clear where he got this list. I'm looking at the manual for the Qume and it claims that it's an electrical and mechanical match for the Shugart 850. Is this a close enough match? Also, the client is in the zipcode 53153. Is there someone near there who I can coax into taking a look? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.
