Has anyone seen/heard/tested such a beast? I've given up trying to replace my Model 50's 20MB HD for under $500. Maybe now I can work around it! Any help, experiences, suggestions will be appreciated. mike (davis@louie.udel.edu)

May never be available through distribution, as the support for it is quite hairy. Microchannle is not microchannel is not microchannel. Through the developement period of the 1640 each time we tested a microchannel machine we found something else we had to do to make th adapter work. To date, the 1640 will still not work in a IBM Model 70. Although I think some things are in the works to correct that. But due to each and every micro-channel machine being slightly different it makes it rahter difficult to put the host adapter in distibution. It's quite a shame too. The 1640 is software compaible to the 1540 family of AT adapters, but has a 20Mhz processor as opposed to the 10Mhz processor on the 1540 family. It really screams. The only widely available palce I can think of that would have it would be Tandy. Although keep in mind that it may not work in a Model 50. Nothing Tandy has done, it's just that MCA is not MCA is not MCA. Roy Neese Adaptec Central Field Applications Engineer UUCP @ {texbell,attctc}!cpe!adaptex!neese merch!adaptex!neese
