Could a helpful soul post the address and cost details for getting the ADE chip from Berkeley for the SH 204? I'd be most appreciative. Larry Rymal <Z4648252@SFAUSTIN.BITNET>

BTW, for netters who don't know about this neat chip I will repeat the problem it solves. (Shhhhh, Atari, I know you don't think it happens) The SH204 has an embedded Adaptec 4000A licensed controller. The controller retries on read error, so one rarely gets one until its unrecoverable. Now when the Adaptec tries to send an error status back to the ST, the Atari host adapter card 'looses' the error. Boo. Since one rarely gets read or write errors, the way to show this up is to access logical unit 1 on a SH204. (normally you use lun=0). While the adaptec reports 'no such drive, error' the atari receives, 'its ready, lets go'. Boo. THis is why the wierd switch in the Spectre/Magic Sac menues to indicate a SH204. The BMS 'chip' replaces the PLA in the Atari Host Adaptor. It works. I have one. Question to the world: Do other Atari Hard Drives show this symptom? You see it if you use Supra drivers and find more partitions than you have. Howard C. Johnson ATT Bell Labs att!lzaz!hcj hcj@lzaz.att.com
