I am sorry about writing in English, but my German is ... Does anyone know how to put Ajax chip to Mega ST. I have been thinking about putting a 1.44 MB drive to my Atari but after all the stories about overheating WD-chips I desided it is not worth it. But now you can buy Ajax, so it might be a better idea. Perhaps it is in Profibuch, but I am still waiting for it. Actually I ordered it in May... -- * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Kimmo Lahtinen E-Mail : lahtinen@gideon.fmi.fi Finnish Meteorological Institute Phone : +358 0 758 1322 Possessed by a Spirit G3 Fax : +358 0 758 1396

But now you can buy Ajax, so it might be a better idea. Simply plug the Ajax in instead of the WD1772. There's nothing more to do because they are fully pin compatible. You need some hardware to use HD disks on the ST, of course. *************************************** * Uwe Seimet * * seimet@rhrk.uni-kl.de * * seimet@chemie.uni-kl.de * *-------------------------------------* * I really hate this damned machine, * * I wish that they would sell it. * * It never does that what I mean * * but only what I tell it. * ***************************************

You need some hardware to use HD disks on the ST, of course. Fine! (except the Ajax chip is quite expensive) Do you know can I use same modifications as with WD1772 to get HD to works? I have one that uses a GAL and it is quite simple. Or is there better ways with Ajax? -- * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Kimmo Lahtinen E-Mail : lahtinen@gideon.fmi.fi Finnish Meteorological Institute Phone : +358 0 758 1322 Possessed by a Spirit G3 Fax : +358 0 758 1396

Or is there better >ways with Ajax? You can use the same modifications, indeed. Because both chips are pin compatible I don't think there is any other way. BTW, Ajax can also be used with 32 MHz clock rate. That means that it's possible to use ED drives with it. Of course you need some hardware for this, but it should be nearly the same that you need with HD drives. *************************************** * Uwe Seimet * * seimet@rhrk.uni-kl.de * * seimet@chemie.uni-kl.de * *-------------------------------------* * I really hate this damned machine, * * I wish that they would sell it. * * It never does that what I mean * * but only what I tell it. * ***************************************
